Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photothermal conversion type heat mode recording material and an image receiving material, and more particularly to a photothermal conversion type heat mode having a flexible intermediate layer for obtaining a high-definition image and applied to a color proof or the like. The present invention relates to a recording material and an image receiving material.

[0002]

2. Description of the Related Art In light-heat conversion heat mode recording, an image is obtained by transferring an ink layer from a recording material to an image receiving material and retransferring the ink layer from the image receiving material to a final recording medium. Adhesion between the material and the image receiving material has an important meaning. In particular, when the image has high definition, foreign matters such as dust and fibrous powder attached to these material sheets have a great influence on the image.

A color proof that reproduces halftone dots requires a resolution of at least several μm to several tens of μm, and foreign substances of the same level cannot be ignored.

Japanese Patent Application No. 4-228778 describes that it is effective to provide a soft material for the intermediate layer as a means for improving the adhesion between the recording material and the image receiving material. As a result, the influence of foreign matter attached between the recording material and the image receiving material can be reduced.

[0005]

However, even if the adhesion between the recording material and the image receiving material is good, if the foreign material adheres to the substrate such as a drum that supports these material sheets at the time of transfer, the above material is used. Since the support has no flexibility, only the foreign matter portion rises, causing poor adhesion between the recording material and the image receiving material, and there is a problem that only that portion causes a difference in the distance from the light source, resulting in poor transfer. It was

Therefore, an object of the present invention is to provide a light-heat conversion type heat mode recording material having a flexible intermediate layer which can reduce the influence of foreign matters such as dust adhering between the material sheet and the substrate to obtain a high-definition image. And to provide an image receiving material.

[0007]

The above object of the present invention is to perform imagewise scanning by superimposing the color material layer surface of the photothermal conversion heat mode recording material and the image receiving surface of the photothermal conversion heat mode image receiving material so as to face each other. A photothermal conversion heat mode recording material and / or an image receiving material used for heat mode recording in which the color material layer or the color material is transferred to the image receiving surface by exposure,
It is achieved by a light-heat conversion type heat mode recording material and an image receiving material having a cushioning backing layer having a penetration of 10 or more.

The penetrability referred to here means a measured value (unit: mm) under the standard test conditions of JIS K2530-1976, and the higher the value, the less susceptible to foreign matter such as dust.

It should be noted that an additive for preventing blocking of the backing layer is added to the backing layer, an antiblocking layer is provided on the backing layer, and the height of the surface is 10
It is preferable to provide a backing layer having 10 to 3000 convex portions per 1 mm ² or more and to add an antistatic agent to the backing layer or the antiblocking layer, since the effects of the present invention can be more exerted.

The present invention will be described in more detail below.

First, examples of constitutions of the recording material and the image receiving material of the present invention will be shown.

<Recording Material> Flexible Backing Layer / Support / Intermediate Layer / Photothermal Conversion Layer / Ink Layer Blocking Prevention Layer / Flexible Backing Layer / Support / Intermediate Layer / Photothermal Conversion Layer / Ink Layer Convex A backing layer having a part / support / intermediate layer / photothermal conversion layer / ink layer, or a release layer and / or an adhesive layer may be provided.

The thickness of the backing layer depends on the size of foreign matter that can be attached, but is usually preferably in the range of 5 to 50 μm. As a coating method of the backing layer, known methods such as reverse coater, extrusion coater, slide hopper coater, gravure coater, comma doctor, curtain coater and wire bar are used.

Since the surface property of the backing layer influences the transferability, it is preferable that the surface roughness and "waviness" are small. When the reference length is 2.5 mm and the cutoff value is 0.38 mm, the surface roughness is When Ra is 0.5 μm or less, and the reference length is 2.5 mm and the cutoff value is 8 mm, it is preferable that Rmax is “waviness” of 3 μm or less.

When the material of the backing layer has tackiness and thus causes a problem in blocking and transportability during winding, it is preferable to add an antiblocking agent or to provide an antiblocking layer as the outermost layer.

As the anti-blocking agent, silicone oil (including a so-called silicone resin); solid waxes such as polyethylene wax, alkyd wax and Teflon powder; fluorine-based and phosphoric acid-based surfactants;

An antiblocking layer may be provided on the backing layer. As the material of this layer,
A resin that does not have tackiness at room temperature and has a glass transition temperature (Tg) of 30 ° C. or higher is preferable. Examples thereof include, but are not limited to, polyester, polyvinyl chloride, polyamide, polystyrene, polycarbonate, polyvinyl alcohol, methyl cellulose, ethyl cellulose, hydroxypropyl cellulose, gelatin, polyvinyl pyrrolidone, polyvinyl acetal, and polyacetal.

The anti-blocking layer can be formed on the backing layer, or can be formed by laminating with the backing layer by the method described in Japanese Patent Application No. 5-1237. The thickness of the blocking prevention layer is preferably about 0.1 to 3 μm.

As the backing layer of another embodiment of the present invention, there may be mentioned a backing layer in which convex portions having a uniform height are uniformly provided. Specifically, a method such as adding a matting agent or providing a backing layer and then embossing is possible.

It is preferable that the height of the protrusions provided is as uniform as possible. Specifically, when observing the surface properties of a 40 mm × 40 mm square selected arbitrarily for the backing layer with a surface roughness meter or an electron microscope, 95% or more of the protrusions have a height of all the protrusions. It is preferable to be included within the average value of the heights of ± 50%. Further, it is preferable that the maximum height is not more than twice the average value of the heights of all the convex portions.

The average value of the heights of all the convex portions when measured under the above conditions is 20 to 80 μm, depending on the size of foreign matter that can be attached.
Is preferred. Further, it is preferable that the number of the convex portions having a height included within ± 50% of the average value of the heights of all the convex portions is 10 to 3000 per 1 mm ² . The distance between the convex parts is at least

Here, the convex portion means a portion protruding by 5 μm or more in height based on the surface of the backing layer, and the interval between the convex portions means the closest distance between the respective convex portions.

A mixture of a matting agent and a binder can be applied to provide the backing layer with a convex portion. The type of matting agent is not particularly limited, but for example, the inorganic or organic matting agents described in JP-A-4-127142 can be used.

That is, as the inorganic matting agent, oxides (silicon dioxide, titanium oxide, magnesium oxide, etc.), alkaline earth metals (barium sulfate, calcium carbonate, magnesium sulfate, etc.), non-photosensitive silver halide grains (not Aged particles, rhodium desensitized particles, etc.) and glass.

By adding an antistatic agent to the backing layer or antiblocking layer of the present invention, it is possible to greatly reduce the adhesion of foreign matter to the sheet. Examples of the antistatic agent include fluorine-based nonionic, anionic and cationic surfactants; metal oxides such as zinc oxide, titanium oxide and tin oxide; semiconductors such as organic semiconductors.
