Definitions
- Anti-halation layers of photographic light-sensitive films are generally divided into two types, namely, a type where the anti-halation layer remains, but is decolored by processing, and a type where the anti-halation layer is removed by processing. This is the so-called filmremoving type.
- the present invention relates to a photographic light-sensitive film having an improved anti-halation layer of the latter type and more particularly to a photographic light-sensitive film having an improved film-removing type anti-halation layer comprising an alkali-soluble resin.
- a conventional anti-halation layer of the film-removing type is formed on a photographic light-sensitive film by coating on a back layer of the photographic light sensitive film a solution prepared by dispersing or dissolving carbon black or an anti-halation dyestutf in a resin.
- the anti-hal-ation layer of this type has a higher flexibility and smoothness than those formed from a gelatin layer which is frequently used in the case of adopting the film-remaining type anti-halation layer.
- the film-removing type anti-halation layer is removed at development. Therefore no sticking occurs when the back layer of the film is contacted with the emulsion layer after development.
- the anti-halation layer of this type has excellent anti-halation effect and further, since the anti-halatio-n layer has an improved water-resistance, the photographic light sensitive film having the anti-halation layer can be easily handled even in a high humidity condition.
- the anti-halation layer is transferred to the surface of an emulsion layer when it is contacted with the emulsion layer before development.
- an object of this invention is to provide an improved anti-halation layer which is not transferred to an emulsion layer when the anti-halation layer is contacted with the emulsion layer.
- N-substituted amide derived from behenic acid that is, the N-alkyl behenamide represented by the general formula wherein R represents a methyl group or an ethyl group
- R represents a methyl group or an ethyl group
- the suitable proportion of the N-alkyl behenamide to be incorporated in the anti-halation layer is from 7 ice to V part by weight, and preferably to part by weight of the alkali-soluble resin of the anti-halation layer. If the proportion of the amide is less than /100, the transfer-preventing effect is scarcely obtained and if the proportion is higher than the amide is separated from the anti-halation layer due to the poor compatibility of the amide with the resin.
- alkali-soluble resins which may suitably be used in the present invention there are resins having carboxylic acids or the anhydrides thereof at the side chains, such as, maleic anhydride copolymers, cellulose acetate phthalate, acrylic acid copolymers, and the acetate phthalate of polyvinyl alcohol.
- the material for the anti-halation layer is usually composed of the above-mentioned alkali-soluble resin, the alkyl behenamide, and carbon black or an anti-halation dye but by incorporating in the composition a surface active agent, the coating property and film-removing property of the thus formed anti-halation layer can be improved.
- the surface active agent used in this invention may be various anionic surface active agents and non-ionic surface active agents and they may be used alone or as a mixture thereof.
- the invention is effective regardless of the kinds of support materials and anti-halation agents to be incorporated in the anti-halation layer and the manner of coating the substrate of the anti-halation layer.
- Example 1 To the back surface of a cellulose triacetate film was applied a solution having the following compositions to provide an anti-halation layer:
- Example 2 An anti-halation layer was formed by applying to the back surface of a cellulose triacetate film a solution having the following composition:
- a photographic emulsion layer was formed on a substrate on the opposite surface of the film and when the thus prepared film was rolled up firmly and stored in that condition for 1 year, the anti-halation layer was not transferred to the surface of the emulsion layer.
- Example 3 A polyester which has been prepared by condensing a mixture having the following composition:
- Solution A Parts Stearamide 0.2 Methanol 20
- Solution B Parts Stearamide 0.2 Methanol 20
- N-ethyl behenamide 0.2 Methanol 20 The thus prepared anti-halation coating solution was applied to the substrate of a polyester film and dried. A color photographic light-sensitive emulsion was applied to the opposite surface of the film and dried.
- the thus prepared film was slit into 16 mm. in width and 50 m. in length, rolled up and maintained for 24 hours at a temperature of 40 C. and a relative humidity of 80%, no transfer of the anti-halation layer to the emulsion layer occurred in the case where solution B was used whereas the anti-halation layer containing solution A was transferred to the emulsion layer (average adhesion area was 10-20%).
- the anti-halation layer containing the N-alkyl behenamide in this invention has higher anti-adhesion property than the anti-halation layer containing the aliphatic acid amide described in US. Patent 2,732,305.
- a photographic light-sensitive film comprising a support having thereon at least one photographic lightsensitive emulsion layer and an anti-halation layer composed of an alkali-soluble resin and a member selected from the group consisting of carbon black and an antihalation dye on the surface of the support opposite to the emulsion side, said anti-halation layer having incorporated therein an N-alkyl behenamide shown by the following formula:
- R is a :member selected from the group consisting of CH3 and C2H5.
