Definitions

  • This invention relates to an imaging element, and in particular to a silver halide photographic element with improved scratch and abrasion resistance.
  • an absorbing dye in particular, an ultraviolet ray absorbing dye
  • the dyed light-insensitive layer is used, for example, to control the spectral composition of light incident upon a photographic emulsion layer, to act as an antihalation layer between the support and the photographic emulsion layer, or on the side of the support opposite to the photographic emulsion layer to prevent halation caused by light scattering during and after the passage of light through the photographic emulsion layer, or to absorb or to remove ultraviolet light produced by static discharge generated by friction of separation, which occurs when the surfaces of the photographic element come into contact during production or treatment processes.
  • static electricity by charging reaches a certain limiting value
  • atmospheric discharge occurs at a particular moment and a discharge spark fires at the same time.
  • static marks appear after development.
  • the weakening of light-insensitive layers by an absorbing dye dispersion has been a serious problem in, for example, color light sensitive materials, where a light-insensitive layer containing an ultraviolet dye dispersion is often coated as a protective layer on the top of the emulsion layer to remove the ultraviolet light generated by static discharge and for correct color reproduction. Since it is desired to record only visible light, the influence of the ultraviolet light is very apparent. For example, when photographing objects which have a comparatively large quantity of spectral energy in the ultraviolet region, such as a distant view, a snow scene, or an asphalted road, etc. the resulting color images are rich in blue color.
  • a foremost objective of the present invention is to provide a silver halide photographic material which exhibits excellent resistance to such physical scratches and abrasions.
  • a photographic element comprises a support, at least one light-sensitive layer, and a light-insensitive protective layer.
  • the light-insensitive protective layer includes at least two layers, with the layer closer to the support (UV layer) containing at least one ultraviolet ray absorbing dye, a high boiling organic solvent, and a hydrophilic binder, and with the layer farthest from the support (outermost protective layer) containing a processing surviving matting agent and a modified gelatin where at least one carboxylic acid moiety of gelatin is modified into a monoamide of a polyamine whereby at least one additional amine group is introduced.
  • the photographic element of the present invention has a light-insensitive hydrophilic protective layer which includes at least two layers.
  • the layer closer to the support contains at least one ultraviolet absorbing dye, a high boiling organic solvent, and a hydrophilic binder.
  • the layer farthest from the support contains at least one matting agent and a modified gelatin.
  • the content of the hydrophilic binder in the UV layer is defined as the ratio of coating weight of the hydrophilic binder to the sum of the coating weights of the ultraviolet absorbing dyes, high boiling organic solvents, the hydrophilic binder, and other addenda, and is preferably in the range of from 30 to 90%, and more preferably from 40 to 80%.
  • the matte particle in the outermost layer has a mean particle size of from 0.5 to 10 ⁇ m, preferably from 1 to 5 ⁇ m, and most preferably from 1 to 3 ⁇ m, and a coating weight of from 0.01 g/m 2 to 0.3 g/m 2 , preferably from 0.02 g/m 2 to 0.2 g/m 2 , and most preferably from 0.03 to 0.15 g/m 2 .
  • the thickness of the UV layer of the present invention is usually 0.2 to 3 ⁇ m, and preferably from 0.5 to 2 ⁇ m.
  • the thickness of the outermost protective layer is usually 0.4 to 3 ⁇ m, and more preferably 0.6 to 2 ⁇ m.
  • the total thickness of the two layers is 0.6 to 6 ⁇ m, and preferably 1.5 to 4 ⁇ m.
  • the term of "thickness" used herein refers to the thickness of the portion in which no matting agents are present, and measured from, for example, an electron micrograph of a non-swollen cross-section of the light-sensitive material.
  • the modified gelatin for use in accordance with the present invention has some of its free carboxyl groups converted into a monoamide of a polyamine thereby introducing at least one additional amine group.
  • a preferred method of providing such a modified gelatin has been described in detail in U.S. Patent No. 5,219,992.
  • each R is hydrogen, but each R may be an alkyl group as defined below.
  • the polyamine is a diamine, or a derivative thereof.
  • polyamine In the polyamine, at least two amine nitrogens must be separated by a two carbon bridge. In triamines, it is preferred that all three amino nitrogens be separated by two carbons.
  • Polyamines of this type may be acyclic or cyclic. Acyclic diamines of this type are illustrated by ethylenediamine, 1,2-diaminopropane, N-methylethylenediamine and N,N'-dimethylethylenediamine. Diethylenetriamine is another illustrative amine that can be employed. It illustrates the use of triamines such as wherein R and n are as defined below.
  • the polyamine with the characteristic group need not be acyclic, thus, for example, the polyamine may be cyclic, as in piperazine or piperazine derivatives:
  • each R is preferably hydrogen; hence, piperazine is a preferred cyclic amine for use in this invention.
  • One of the hydrogens in the piperazine nucleus may be substituted with a HNR-CHR-CHR- group.
  • another preferred polyamine is N-(2-aminoethyl)piperazine.
  • Other cyclic diamines having at least one pair of ring nitrogens separated by a -CHR-CHR- bridge can be employed. The nitrogens may also be connected by a bridge of one to four carbons.
  • Preferred polyamines have 2 to 12 carbon atoms; more preferably 2 to 8 carbons.
  • the polyamines can be added to the reaction mixture as a salt; more preferably a hydrohalide salt derived from HCl or HBr.
  • ethylenediamine can be added to the reaction mixture as the dihydrochloride,
  • gelatin used herein for the starting material for preparing the modified gelatin according to the invention relates to the protein substance emanating from collagen. However, this term is also intended to encompass other substantially equivalent substances, for example synthetic gelatin.
  • gelatin is classified as alkaline gelatin which is obtained from collagen, for example by treatment with calcium hydroxide; acidic gelatin which is obtained by acidic treatment, for example with hydrochloric acid; enzymatic gelatin which is treated, for example, with a hydrolase and low molecular weight gelatin which is obtained by further hydrolysis of the gelatins mentioned above by different methods.
  • Each of the gelatins mentioned above may be used for the preparation of the modified gelatin required in accordance with the invention.
  • the modified gelatin has the formula: Gel ⁇ CO ⁇ G wherein Gel is a gelatin polypeptide, -CO- is a carbonyl group from a free carboxyl group in an aspartic acid or a glutamic acid moiety in said polypeptide, and G is ⁇ NR ⁇ CHR ⁇ CHR ⁇ NR ⁇ T or wherein each R is independently hydrogen or a primary or secondary alkyl group of one to four carbon atoms, n is a positive integer having a value of one to four, and T is hydrogen or said modified gelatin being further characterized by having from 1% to 40% of the free carboxyl groups in aspartic or glutamic acid moeities in said polypeptide being substitued with G-groups.
  • UV dyes used in the present invention are not particularly limited provided their absorption maximum wavelengths fall within the range from 300 to 400 nm, and they have no harmful effect on the photographic properties of the element.

  • UV dyes used for the present invention are preferably used in a pre-dispersion form (UV dye dispersion), which can be prepared, for example by dissolving the UV dye in a high boiling organic solvent and then adding the resulting solution in an aqueous gelatin solution containing a surfactant such as, for example, sodium dodecyl sulfonate.
