PURPOSE:To improve the coloring property of the title material and the durability of a color picture against light and heat by incorporating a specified cyan dye forming coupler in the photosensitive material. CONSTITUTION:At least one kind of the cyan dye forming coupler shown by formula I is incorporated in the photosensitive material. In formula I, Ar is an aromatic or a heterocyclic ring group which may be substd., Z is a hydrogen atom or a group capable of being released by a coupling reaction with the oxidant of an aromatic primary amine developing agent, R<1> is hydrogen atom or 1-20C an aliphatic group, A is a substd. imino group or a methylene group which may be substd., Q is a nonmetal atomic group necessary for forming 3-7 membered ring together with the group A and a carbon atom which bonds to the group R1. Thus, the durability and the coloring property of the color picture are improved. |
