PURPOSE:To obtain the titled material capable of stabilizing a color image against a heat and a light, and preventing a generation of stain by incorporating at least one of a coupler capable of forming a specific magenta color image, and at least one of the 1st. specific compd. and at least one of the 2nd. specific compd. to the titled material. CONSTITUTION:The titled material contains at least one of the coupler capable of forming the magenta color image shown by formula I, at least one of the compd. shown by formula II and at least one of the compd. selected from the compds. shown by formula III. In formula I, Z is a non-metallic atom group necessary for forming a nitrogen contg. heterocyclic ring, X is hydrogen atom or a substituted group capable of cleaving by reacting with an oxidant of a color developing agent, R is hydrogen atom or a substituted group. In formula III, R<8>-R<10> are each hydrogen atom or halogen atom, etc., Y is an atomic group necessary for forming an indan ring. The used amount of the stabilizer of the magenta color image is preferably 5-400mol%, more preferably 10-250mol% per the magenta coupler shown by formula I. |
