    Abstract: PURPOSE: To obtain a high storage stability for a long time even in a high temp. and high humidity environment by incorporating mixture of a photooxidizing agent, a specified leuco compd., and if necessary, a sensitizer as a color developing system. CONSTITUTION: This material consists of one or more kinds of polymer binders, a color developing system, and if necessary, one or more kinds of polymerizable monomer org. compd., and a photoinitiator or photoinitiating system which can be activated by irradiation, and a normal additive and assistant. As for the color developing system, a mixture of a photooxidizing agent, a leuco compd. expressed by formula I and a sensitizer is incorporated. In the formula I, A, B are groups expressed by formula II, R is a 1-8C alkyl group, aryl group, etc., R is phenyl group, 1-8C alkyl group, etc., R is hydrogen, a halogen or 1-8C alkyl group, R and R are 1-8C alkyl groups or alkylaryl groups having 1-6C alkyl groups. Thereby, the obtd. material has high stability in the color developing system high storage property in a dark place.
