Abstract
1,091,404. U.V.-absorbing layers. EASTMAN KODAK CO. Oct. 28, 1964 [Oct. 28, 1963], No.44012/64. Heading G2C. A light-sensitive colour photographic material comprises a support bearing at least two silver halide emulsions of different spectral sensitivity and a water permeable filter layer comprising a poly-N-vinyl lactam and an U.V. absorbing compound having an acid or salt group which is such that the compound is mordanted in the filter layer by the poly-N-vinyl-lactam except when the filter layer is permeated by an aqueous alkaline solution when the compound is diffusible in that layer. Specified U.V. absorbing compounds are those of the formulae:- wherein R is H, alkyl, alkoxy, OH, CN, halogen, or amino and R 1 is sulpho or carboxy or alkali metal salts thereof, wherein R 2 is H, alkyl, aryl or substituted aryl, R 3 is a sulpho- or carboxy-substituted aryl, -substituted aryl or -benzamido aryl group, or alkali metal salts thereof and Q is O, S, or an imino group; wherein R 4 -R 6 are H, alkyl, alkoxy, OH, amino, halogen, NO 2 or sulpho or carboxy or alkali metal salts thereof at least one of R 4 -R 6 being an acid or salt group, and wherein R 7 is an alkyl or alkoxy group and R 8 is an aryl group containing a sulpho or carboxy group or alkali metal salts thereof or a sulpho- or carboxy-substituted benzamido aryl group or alkali metal salts thereof. Specified poly-N- vinyl lactams are poly-N-vinyl-2-pyrrolidone, poly-N-vinyl-5-methyl-2-pyrrolidone and poly- N-vinyl caprolactam. The filter layer may contain an additional binder e.g. gelatine, albumin, cellulose acetate, polyvinyl acetal or hydrolyzed polyvinyl acetate.
