Abstract

NEW MATERIAL:Compounds of formula[wherein R1 is alkoxy, a gp. of formula- NR4R5 (wherein R4, R5 are alkyl); R2 is H, alkoxy; R3 is alkyl, aryl; X is H, aryl; X is H, alkyl; m is 1, 2; n is 3, 4; M is monovalent cation].
USE: Light absorbing dye for use in silver halide photographic material. The dye exhibits good decolorizing properties. Contamination due to coloration caused by the remaining dye after development is improved.
PREPARATION: A hydroxybenzoic acid is used as a starting material, which is converted to a hydroxybenzoylacetic ester. This ketoester type cpd. is alkylated. The alkylated material is reacted with a hydrazine to produce a pyrazolone which is then reacted with an aldehyde in alcoholic solvent to obtain the compound of formula.
