PURPOSE:To obtain a photosensitive coating compsn. which gives a protective film having adhesion and hardness capable of exhibiting performances as a protective film, by blending a photosensitive material with a filler mixture of talc and a finely divided aluminosilicate crystal. CONSTITUTION:A compsn. contains a photosensitive material and at least 5wt.% filler mixture of talc and a finely divided aminosilicate crystal. As the photosensitive material, any of a monomer and its prepolymer can be used. Preferred photosensitive epoxy resins are those having ethylenically unsaturated bonds capable of undergoing an addition reaction or a polymn. reaction by irradiation with actinic rays and curable epoxide groups and contg. a curing agent and a curing accelerator. The filler mixture has an average particle size of pref. 0.1-10mum.
