Color photographic material, e.g. color (reversal) paper or for color diffusion transfer or silver dye bleach process, contains e.g. 2-thio-4-oxo-thiazolin-5-yl-cyanoacetamide salt as gap sensitizer

摘要

Color photographic material, having silver halide emulsion layers containing red, green and blue sensitizer(s) and cyan, magenta and yellow couplers respectively on a base. Another spectral sensitizer is an alpha -substituted- beta -(2,4-dioxo-, 2-thio-4-oxo- or -2-seleno-4-oxo-oxazolin-5-yl, -thiazolin-5-yl, -selenazolin-5-yl or -imidazolin-5-yl)-acet-amide, -thioamide or -selenoamide salt (I). Color photographic material, which has silver halide emulsion layers containing red, green and blue sensitizer(s) and cyan, magenta and yellow couplers respectively on a base, contains another spectral sensitizer, which is an alpha -substituted- beta -(2,4-dioxo-, 2-thio-4-oxo- or -2-seleno-4-oxo-oxazolin-5-yl, -thiazolin-5-yl, -selenazolin-5-yl or -imidazolin-5-yl)-acet-amide, -thioamide or -selenoamide salt of formula (I); X1 = oxygen (O), sulfur (S), selenium (Se) or imino (N-R); X2, X3 = O, S or Se; R = hydrogen (H), (het)aryl or T; T = an optionally substituted alkyl, sulfoalkyl, carboxyalkyl group or -(CH2)l-SO2-Y-SO2-alkyl, -(CH2)l-SO2-Y-CO-alkyl, -(CH2)l-CO-Y-SO2-alkyl, -(CH2)l-CO-Y-CO-alkyl or -(CH2)n-NH-SO3<->; l = 1-6; Y = NH or N<->; n = 2-6; R1, R3, R4 = T; R2 = carbonamido, cyano, halogen, H, alkyl or (het)aryl; M<+> = optionally a counterion.
