Investigation of Reactions of Pyrazolin-Azomethin Dyes with 2-Pyrazolin-5-one

The pyrazolin-azomethin dyes (3a-d) from 1-phenyl-3-methyl-2-pyrazolin-5-one and various photographic developers have been obtained.The reactions of decolourization of dyes during the 3-methyl-1-phenyl-2-pyrazolin-5-one action was investigated.We ascertained that the substituent changes in the developer had not only the influence on decolourization rate but they also had influence on the order change of the reaction.The various solvents had the same influence on the reaction rate of decolourization.
