PURPOSE:To improve the color stain of the titled material by incorporating an anti-dispersive scavenger of the oxidant of a color developing main agent which has >=3.0 relative reaction rate of soln. system, in the titled material. CONSTITUTION:The titled material contains the anti-dispersive scavenger of the oxidant of the color developing main agent which has >=3.0 relative reaction rate of soln. system. The reaction between the oxidant of the color developing main agent and the anti-dispersive of the oxidant of the color developing main agent is a redox reaction. Said scavenger is deactivated by reacting with the oxidant of the color developing main agent whereby the reaction of said oxidant and a coupler is controlled. Thus, said scavenger is very effective as the color stain inhibitor of the titled material. |
