摘要：PURPOSE:To improve stability at the time of preservation by housing a reducing agent in a solid fine particle state in the photosensitive microcapsule. CONSTITUTION:The reducing agent is housed in the solid fine particle state into the photosensitive microcapsule contg. a silver halide, the reducing agent, a polymerizable compd., and color image forming materials. The base contains the photosensitive microcapsules and a binder thereupon. This reducing agent has the function to reduce the silver halide and/or the function to accelerate (or suppress) the polymn. of the polymerizable compd. The housing of the reducing agent into the microcapsule may be executed by incorporating the reducing agent into the polymerizable compd. in the state of dispersing the reducing agent in an aq. medium or may be directly dispersed in a solid state into an oily medium, such as polymerizable compd. The reducing agent is preferable so that the solubility to the aq. medium or the oily medium is <=5% at 25 deg.C and more preferable <=1%. The higher solubility is preferable at 140 deg.C.
