PURPOSE:To obtain the titled composition having less tendency for remarkably reducing a change on standing, and preventing an increase of a fog at the time of continuously processing by incorporating an aromatic primary amine coupler developing agent and a specific compd. to the titled composition. CONSTITUTION:The titled composition contains the aromatic primary amine coupler developing agent and the compd. shown by formula I wherein R<1> is hydroxyalkyl group (2-6C group) such as 2-hydroxyethyl group and 4- hydroxybutyl group, etc., R<2>-R<4> are each alkyl group (1-6C group) such as methyl, ethyl and propyl group, etc., Q is a substd. or an unsubstd. carbon ring (5-10C group) such as cyclohexane ring and benzene ring etc., (n) is an integer of 0-4. The concrete example of the compd. shown by formula I is exemplified by the compd. shown by formula I-1. The titled developing composition has an excellent stability and coloring property, and gives the color developer which is remarkably reduced the increase of the fog at the time of continuously processing, etc. |
