PURPOSE:To lessen an increase in yellow stains and to form a fast magenta color image by incorporating prescribed magenta couplers and specific compds. into a titled material. CONSTITUTION:>=1 kinds of the pyrazoloazole magenta couplers expressed by the formula I and >=1 kinds of the compds. expressed by the formula II are incorporated into the titled photosensitive material. In the formula, R<10> denotes H, substituent; X denotes H, a group which is eliminated by the coupling reaction of an arom. primary amine with the oxidant of a developing agent; Za, Zb, Zc denote (substd.)methine, etc., where one of Za-Zb and Zb-Zc is double bonds and the other is single bond; Z denotes an arom., aliphat. carbon ring, etc.; R1-R3 denote H, halogen, etc.; (l) denotes 1-3; (m) denotes 1-4. The photosensitive material which is fast in the color image under dark preservation and photoirradiation and decreases scumming is obtd. according to this constitution. |
