Abstract
NEW MATERIAL:Compounds of formula I [wherein R is H, lower alyl; R1 is alkyloxy group contg. sulfo group; -NR6R7 (wherein either or both of R6 and R7 is/are alkyl group contg. sulfo group); R2 is H, alkyloxy group contg. sulfo group; R3, R4 are lower alkyl, aryl; R5 is H, lower alkyl].
EXAMPLE: Compound of formula II.
USE: Light absorbing dye for use in silver halide photosensitive material for photography.
PREPARATION: Aminoguanidine sulfate (or carbonate or nitrate) is reacted with alkyloyl- or aryloylacetic ester in the presence of sodium alcoholate to obtain a pyrimidinyl pyrazolone derivative which is then reacted with an aldehyde derivative in a solvent such as dimethylformamide or alcohol such as methanol or ethanol.
