Definitions

  • Anti-halation layers have to meet the following requirements: their absorptive power should be adapted to the optical sensitivity of the silver halide emulsions; they should lose color quickly,
  • the layers should also withstand mechanical influences which remove the dyestufi itself or which could damage the thin layer.
  • a further object of our present invention is to provide a photographic light-sensitive single or multi-layer silver halide material containing at least one of the said colored photographic layers.
  • our invention consists in the prodnot and the method of producing same, as hereinafter are more particularly described in the methine dyestuffs of the type that is obtainable as, for, instance," by condensationof substituted or unsubstituted aliphatic, aromatic or heterocyclic' aldehydes with suitablesubstituted anilcines' oramines, preferably in equimolar' quanti
  • the color intensity of the dyestuffs is considerably increased.
  • para-anisidin para-amidodiphenylam-ine, ortho-anisidin, para-toluylediamine, l m. dibromoanthranilic acid, aminophenyltliiocarbamide.
  • Suitable aldehydes are, ea g.,. para-dimethyl- Example 1 1 mol anthranilic acid and 1 mol para-dimethylaminobenzaldehyde are heated in a diluted alcoholic solution. A colored combination separates immediately and is crystallised from alcohol (iJOOBK 3 .ErampZe 2 1 mol anisic aldehyde is condensed as in Example 1 with 1 mol amidodiphenylamine to an azomethine dyestufi of the following probable structure This azomethlne dye base is condensed in equimolar proportions with salicyclic acid in alcohol.
  • Example 3 COOH All of the above dyestuffs are suitable for all photographic purposes where a layer discolorable in a weak alkaline medium is required, as e. g. for filter layers, anti-halation layers, back layers, and also for direct addition to the silver halide emulsion.
  • Photographic material containing at least one light-sensitive silver'halide emulsion layer and a colored non-sensitive layer including the reaction product of a basic azomethine dyestuif, obtained by condensing in equimolar proportions an aldehyde selected from the group consisting of p-dimethylaminobenzaldehyde and p-dimethylaminocinnamic aldehyde, and anthranilic acid, with methylene disalicylic acid, said reaction product; corresponding to the following formula:
  • A represents the atoms necessary to complete with H benzoic acid
  • B represents the atoms necessary to complete with OHC- an aldehyde selected from said group of aldehydes
  • R represents the atoms necessary to complete with H methylene disalicylic acid, the radical of the latter acid being linked to the N-atom so that 4 the salt-formingOI-I remains intact
  • n represents a positive integer of from 1 to 2.
  • Photographic material containing at least one light-sensitive silver halide emulsion layer and a colored non-sensitive layer including the dyestuff of the formula:
  • Photographic material containing at least one' light-sensitive silver halide emulsion layer and a colored non-sensitive layer including the dyestuff of the formula:
