PURPOSE:To reduce a generation of fog in the image by releasing a specific compd. with a complex forming reaction in the image forming reaction system comprising the slightly soluble specific metal compd. and a compd. capable of carrying out a complex forming reaction with a metal ion constituting said slightly soluble metal compd. in the presence of water as a medium. CONSTITUTION:In the image forming reaction system comprising the slightly soluble metal compd. shown by formula I and the compd. capable of carrying out the complex forming reaction with the metal ion constituting said slightly soluble metal compd. in the presence of water as the medium, the compd. shown by formula II, is released by reacting said two compds. in the presence of water. When the slightly insoluble metal compd. or the complex forming compd. is incorporated into the layer mounted on a substrate body, although the used amount of said compds. depends on a kind of said compds., a particle size of said slightly soluble metal compd. and a complex forming reaction rate, etc., the used amount of each said compds. is preferably <=50wt%, further preferably 0.01-30wt% on the weight basis of each coated films. |
