CONSTITUTION:The photographic film cartridge 20 consists of a spool 1, a photographic film 2 which is detained at one end to the spool 1 and is wound in the form of a roll, and a cartridge body 3. The stable film delivering is not possible unless the free space in the cartridge is V<=0.25 and V=(B-A)/B in the voids V defined as follow: A is the winding sectional area of the film, B is the sectional area in the cartridge. Further, the coefft. of static friction of both surfaces of the film to be built in the cartridge having a film delivery function is required to be confined to <=0.25. The coefft. of static friction of the film can be lowered to <=0.25 simply by incorporating a slipping agent into the emulsion layers and back layers of the film.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a silver halide photosensitive material. More specifically, the present invention provides a compact photographic material that facilitates the loading of photographic film into a camera, and which improves the transportability of the film wound into a roll during storage of the photographic material. Regarding photosensitive materials.

(Prior art) In conventional photographic film cartridges, the photographic film was tightly wound around the spool inside the cartridge and stored in a loosely wound state, so even if the spool was rotated in the opposite direction to the film winding direction, Photographic film could not be sent outside the cartridge. For this reason, it has been necessary for the photographer to pull out the leading end of the photographic film by an appropriate length from outside the cartridge in advance, and then load the leading end of the photographic film into the film feeding mechanism within the camera.

However, this operation is time-consuming and requires a certain degree of skill, so loading errors often occur.If a loading error occurs, there is the problem that the photographic film is taken without being wound. Ta.

Therefore, a camera that does not require such operations has been desired.

Such a camera can be realized by allowing photographic film to be fed from inside the cartridge. If photographic film can be fed out from inside the cartridge, the film can be engaged with the film advance mechanism inside the camera by feeding out the leading edge of the film. No longer needed. Therefore, instead of the conventional cartridge, a cartridge that can feed the film from inside is required.

A conceivable method for feeding the photographic film from inside the cartridge is to rotate a spool around which the photographic film is wound in a direction opposite to the film winding direction to feed the photographic film to the outside of the cartridge. In this method, it is necessary to reduce the free space inside the cartridge to a certain level. This is because if the free space is large, the film will turn over inside the cartridge, and the rotation of the spool will no longer act as a force to push the leading edge of the film out of the cartridge. Furthermore, the conventional cartridge main body is large, which is not suitable for downsizing the camera.

However, when the free space is reduced below a certain level, the force that tries to expand the winding diameter of the photographic film inside the cartridge increases, and this pressure causes the photographic film to not be fed out, leaving blocking marks, and causing scratches on the surface.

As a method to solve the above-mentioned problem, attempts have been made to generally provide a matting agent for preventing blocking in the outermost layer of the photographic film, but this resulted in increased haze and deterioration of graininess.

(Object of the present invention) An object of the present invention is to provide a photographic material in which a photographic film rolled up in a cartridge having a small porosity can be easily fed out from inside.

Object of the present invention is to provide a spool, a photographic film having at least one layer of photosensitive silver halide on a support which is wound on the spool in the form of a roll with one end fixed to the spool; It consists of the cartridge body, and the porosity inside the cartridge is V.

The cartridge used in the present invention will be described.

The cartridge used in the present invention is primarily made of synthetic plastic.

In forming the plastics of the present invention, a plasticizer is mixed into the plastics as necessary. Examples of plasticizers include oligoctyl phosphate, tributyl phosphate, dibutyl phthalate, diethyl sebacate, methyl amyl ketone, nitrobenzene, T-valerolactone,
Representative examples include di-n-octyl succinate, bromonaphthalene, and butyl palmitate.

Specific examples of plastic materials used in the present invention are listed below, but the invention is not limited thereto.

Specific examples include polystyrene, polyethylene, polypropylene, polymonochlorotrifluoroethylene, vinylidene chloride resin, vinyl chloride resin, vinyl chloride-vinyl acetate copolymer resin, acrylonitrile-butadiene-styrene copolymer resin, methyl methacrylic resin, vinyl formal resin, Examples include vinyl butyral resin, polyethylene terephthalate, nylon, phenol resin, and melamine resin.

Particularly preferred plastic materials for the present invention are polystyrene, polyethylene and polypropylene.

Further, the cartridge of the present invention may contain various antistatic agents. Antistatic agents are not particularly limited, but include carbon black, metal oxide particles, nonions, anions, cations, betaine surfactants, and nonions. , anion,
Cationic and betaine polymers can be preferably used. These anti-static cartridges include Japanese Patent Application Laid-open Nos. 1-312537 and 1. -312538. Especially, the resistance at 25℃ and 25%RH is I
Q11Ω or less is preferable.

Cartridges are usually made from plastic mixed with carbon black or pigments to provide light-blocking properties.

Furthermore, although the shape may remain the same as the current size, it is effective to reduce the size of the camera by changing the diameter of the cartridge, which is currently 25 m/m, to 22 m/m or less, preferably 20 m/m or less, and 14 m/m or more.

The volume of the cartridge case is preferably 30c4 or less, preferably 25c1 or less, and more preferably 20d or less.The weight of the plastic used for the cartridge and cartridge case is 1g or more and 25g or less.
Preferably it is 5 g or more and 15 g or less.

The ratio of the internal volume of the cartridge case to the plastic used in the cartridge and cartridge case is 4~
0.7, preferably 3-1.

The free space inside the cartridge has a porosity V defined below.
In this case, the film cannot be fed stably unless it is VS2.25 V-(B-A)/B, where A is the winding cross-sectional area of the film and B is the cross-sectional area inside the cartridge, as shown below. is defined as

A - (film thickness) * (film length) B' (f
J-) Ridge body cross-sectional area) - (spool cross-sectional area) All measurements of dimensions are carried out at a temperature of 25° C. and in a 50% atmosphere. The length of the film is the length from the tip to the end of the film. If the leading edge of the film is not straight, use the most protruding end as the leading edge. When the end of the film is inserted into the spool, the insertion opening of the spool is the end of the film. The thickness of the film is the sum of the thicknesses of all components such as the film support and the gelatin layer including the hole side.
ctric Eo, Ltd E 1 electronic
M 1cro-setsr ) is obtained by measuring the thickness at arbitrary 10 points and averaging it. The spool cross-sectional area refers to the cross-sectional area of the portion of the spool around which the film is wound.

The cross-sectional area of the cartridge body means the cross-sectional area of the inside of the cartridge, not at the upper or lower ends of the cartridge, but at the cross-section of the portion where the film is accommodated. If there is a protrusion (lip) provided inside the cartridge for the purpose of controlling the position of the film or improving the slippage, the cross-sectional area of the inside of the protrusion is used. If the method uses a flange, etc. other than the cartridge body to arrange the refilm winding,
The inner cross-sectional area of the flange protrusion, etc. that defines the position of the outermost periphery of the film is used.

The value of porosity ■ is 0〈■≦0.25, but 0.04≦
More preferably, V≦0,22, and 0.08≦V
Most preferably, ≦0.22.

Examples of the cartridge of the present invention are shown in FIGS. 1A and 1B. The photographic film cartridge 20 has a spool 1,
It consists of a photographic film 2 wound into a roll with one end secured to a spool 1, and a cartridge body 3. spool l
is rotatably attached to the inside of the cartridge body 3 around an axis, and can be rotated from outside the cartridge body 3.

The cartridge body 3 is provided with a photographic film drawer opening 4 for pulling out the photographic film 2, and the cartridge body 3 is provided on the inner surface of the photographic film pullout opening 4.
A light shielding member 4A is attached to keep the interior in a light shielded state.

In the photographic film cartridge 20 of this embodiment,
A pair of ribs 8 extending in the circumferential direction along the inner surface of the cartridge body 3 and having a width of about 15 to 20% of the film width are provided at both ends of the film 2 in the width direction. The rib 8 opens in the direction of the film outlet 4 so that the photographic film 2 can be pulled out from the film outlet 4. The lip 8 presses the film 2 from the outermost surface to maintain the film 2 tightly wound around the spool l. The cartridge body cross-sectional area in this case is the area inside the lip 8.

The outer diameter of the spool 1 is determined as follows. While keeping the film's innermost periphery 2A in contact with the spool 1's outer periphery, the film 2 is tightly rolled around the spool 1 (as mentioned above, this is difficult. In order to prevent the formation of such a gap, it is necessary to reduce the porosity V to 0.25 or less.Also, the distance between the innermost circumferential surface of the film 2A and the spool 1 If H is too large, a reversal phenomenon of the film 2 as shown in Fig. 2 will occur.For this reason, the outer diameter of the spool 1 should be set to The distance H between the two is 2
It is desirable that the spool outer diameter A is equal to the inner diameter of the cartridge main body B, the rib thickness T,
If the thickness of the film is C and the roll length that changes depending on the length of the film is D, then B/2-A/2+H+C*D+T, so A/2-B/2-T-C100 The interval H is 1(-B/2-A/2~C*D-T, so the outer diameter A of the spool when H≦2mm
becomes B/2-R-C10-2≦A/2.

By setting the interval H to 2 mm or less and setting the spool rotation torque to 0.8 Kgf-cm or less, it is possible to prevent the photographic film 2 from reversing. It is not necessary to provide the lip 8 along the entire circumferential direction along the inner surface of the cartridge main body 3, and it may be provided only on a part of the circumferential direction of the inner surface of the cartridge main body 3. In addition to being provided only at both ends of the film 2 in the width direction, it may be provided over the entire width of the film 2.

Next, the coefficient of static friction on both sides of the film incorporated in the cartridge having a film feeding function of the present invention is 0.25 or less, and this point will be described below.

In the present invention, the static friction coefficient of 0.25 or less means that the sample is heated to 2.
After moistening for 2 hours at 5℃ and 60%RH, HEIDO
This is a value measured using a 5 mmφ stainless steel ball using an N-10 static friction coefficient measuring device, and the smaller the value, the better the slipperiness.

By reducing the coefficient of static H friction, the distance ** between the emulsion surface of the film and the back surface or the inside surface of the cassette and the film, as well as between the film and the cassette outlet when the film is fed out from the cassette by rotating the spool, can be reduced. A reduction in driving torque can be achieved, and damage to the film can be prevented.

5 or less, preferably 0.23 or less, more preferably 0.21 or less, particularly preferably 0.20 or less. At this time, it is preferable that both the emulsion surface and the back surface are small, but the smaller the back surface, the better.

In order to make the static friction coefficient of the film of the present invention 0.25 or less, a slipping agent may be contained in the hole side layer and the back layer of the film, and it is particularly preferable to contain a slipping agent in the outermost layer on both sides.

The lubricant can be contained in the coating solution and applied, or it can be attached to the film after the film has been prepared. There is also a method using a code method, a spin code method, etc.

The slip agent used in the present invention reduces the coefficient of static friction of the film to 0.

Further, the film of the present invention preferably has a magnetic recording layer for recording various information. For example, the film may have a transparent magnetic layer on the entire surface or may have a striped recording layer.

Inputting various types of information into the photosensitive material is a very important means for improving the operability and simplifying the camera in the future. The magnetic recording method is important as an information input means because it allows arbitrary input/output and is inexpensive, and has been studied in the past.

For example, by appropriately selecting the amount and size of the magnetic particles contained in the magnetic recording layer, the magnetic recording layer can be made transparent so that it has the necessary transparency for the sensitive material at the time of photographing, and also does not adversely affect the granularity. Providing a support on the back surface of a sensitive material is disclosed in U.S. Pat.

By providing these magnetic recording layers and input/output methods, it is now possible to incorporate various information into the photosensitive material, which was previously difficult to do. It is now possible to input and output information such as conditions, the number of reprints, the location to be zoomed in, development conditions such as Mesosefuji, printing conditions, etc. to the magnetic layer of the photosensitive material. Furthermore, TV/
It has the potential to be applied as a signal input/output means when directly outputting a video image from a photosensitive material to create an image.

1-2) Preparation of photosensitive material After corona discharge treatment is applied to the side opposite to the bank layer of the undercoated cellulose triacetate film support, each layer having the composition shown below is coated in a multilayer manner to prepare a multilayer color photosensitive material. A sample was prepared.

(Photosensitive layer composition) A photosensitive layer was prepared in exactly the same manner as the photosensitive layer described in Example 1 of JP-A-2-93641.

However, the slip agent of the present invention was added to the second protective layer as shown in Table 1.

(Processing of sample) The sample was cut into a 24-sheet film having a width of 35 mm and the format shown in FIG. 1, and wound into a cartridge. The porosity is shown in Table 1.

These samples were developed as follows.

Color development 3 minutes 15 seconds Bleach White 6 minutes 30 seconds Water Wash 2 minutes 10 seconds Fixed arrival time: 4 minutes 20 seconds Water Wash 3 minutes 15 seconds Safe Fixed 1 minute 05 seconds The composition of the treatment liquid used in each step was as follows.

(]) Evaluation of static friction number After conditioning the sample at a temperature of 25°C and a humidity of 60% RH for 2 hours, a HEIDON-10 static friction coefficient measuring machine was used to measure the sample for 5 m
The measurement was performed using a stainless steel ball of mφ. The smaller the value, the better the slipperiness.

(2) Evaluation sample of film feeding torque from cartridge was cut into 35mm width and 1.2m length at 25°C270
After adjusting the humidity to %RH for 3 days, it was loaded into the cartridge shown in FIG. 1 under the same conditions.

This sample was placed in an aluminum/polyethylene moisture-proof bag and sealed at the same temperature and humidity for 53 days at 40°C. Rotate the spool (Fig. 1 (A) 1) under the conditions of 25°C, 570% RH, and remove the sample from the film outlet (
The torque coming out from FIG. 1 (A) 6) was measured and evaluated. The larger the value, the worse the delivery performance.

(3) Scratch resistance evaluation A diamond needle with a radius of 0.025 mm at the tip is applied vertically to the sample bank surface (the surface not coated with photosensitive material) before development processing, and a continuous load is applied to the sample bank surface by 60 cm.
Scratch at a speed of /m. (25°C, 160% RH) The sample after scratching was placed on a Scherkasten, and the load at which the scratches became visible in transmission was defined as the scratching strength.

The larger the value, the better.

(4) Evaluation of output errors in microrecording Using the signal input method disclosed in World Publication No. 90-04205 mentioned above, a magnetic head was used to output a sensitive material 300 times with magnetic input from the back side. The number of times is shown. The sensitive material is
This output error evaluation was also performed for those that were subjected to magnetic input and then developed.

The temperature and humidity in the evaluation were 25°C and 180% RH.

As can be seen from Table 1, the control of test #41-1 had a large static friction coefficient and was inferior in all aspects of delivery torque, scratch resistance, and magnetic output error. Comparative samples 1-2 to 1-6, which had a porosity of 0.2 or less and only contained a slip agent on either the back side or the milk side, had slightly improved delivery torques, but were insufficient. Furthermore, it was not possible to satisfy all aspects of scratch resistance and magnetic output error. On the other hand, even when the porosity is 0.2 or even 0.1, samples 1-7 to 1-10, in which the coefficient of static friction on the emulsion surface and the back surface have the values of the present invention, show that the feeding torque and I was satisfied with all aspects of scratch resistance and magnetic output error.

Example 2 Co-coated T ferric oxide (acicular particles, specific surface area 38
A dope solution (A) having the following composition was prepared using a solution obtained by cross-dispersing Hc-8000e) in cellulose triacetate, and a separate dope solution (B) containing no magnetic recording material was prepared.

Films were formed by co-casting onto a casting band using a dual slip die so that (A) and (B) had a buffy coating of 5 μm and 110 μm, respectively, with (A) being the upper layer. At this time, a spacer was installed in Surin 1 of (A) so that the width of the magnetic recording layer was 4 mm and the interval between the magnetic recording layers was 26 mm.

Next, the following protective layer for a back layer was coated on the base having this magnetic recording layer.

Cellulose diacetate 0.2 g/Aerosil 0.02-poly(methyl methacrylate/divinylbenzene) (mole ratio 90:10. Average particle size 1.5 μm) 0.03 l Slip agent
Listed in Table 2 Next, the opposite side of the obtained magnetic recording layer was subjected to a normal undercoating treatment, and then a color negative photographic emulsion layer having the same formulation as Sample 101 described in the Examples of JP-A-2-44345 was coated. Established. However, the slip agent of the present invention was also added to the second protective layer as shown in Table 2.

Then, each sample was slit to a width of 35 mm, so that magnetic stripe layers with a width of 4 mm were placed on both sides. On this magnetic stripe, a track width of 0°7 mm and a 3-channel head capable of inputting and outputting with a width of 0.7 mm between racks was used to produce 100 OBPI at a feed rate of 30 mm/3.
Recorded at a recording density of

In addition, each head has the same performance, and the head gear is l.

5μ, The number of turns is 1000.

The evaluation was carried out in exactly the same manner as in Example 1. Shown in the table.

As can be seen from Table 2, samples 2-7 to 2-10 having the static friction coefficient of the present invention are excellent in all aspects of feeding torque, scratch resistance, and magnetic output error, despite having a small porosity. It was something like that.

In contrast, Control Sample 2-1 and Comparative Sample 2, which has a small coefficient of static friction only on one surface on the emulsion side or back side,
-2 to 2-6 could not satisfy all the performances at the same time.

(Effects of the Invention) It consists of a spool, a photographic film having at least one layer of photosensitive silver halide on a support whose one end is fixed to the spool and wound around the spool in the form of a roll, and a cartridge, with a void inside the cartridge. In a photographic material having a ratio V of 0.25 or less, if the coefficient of static friction on both sides of the silver halide photographic material is 0.25 or less, the photographic material has excellent feeding torque and scratch resistance, and has a magnetic recording layer. In the case of materials, the number of magnetic output errors is also small, which is excellent.
