PURPOSE:To obtain the title composition sufficiently curable only by ultraviolet- light irradiation in a short time, having high strength by blending an acryloyl- containing photopolymerizable low-molecular substance, etc., with a specific photopolymerization initiator, a specific radical polymerization initiator, a specific storage stabilizer and specific pigment. CONSTITUTION:(A) An acryloyl-containing photopolymerizable low-molecular substance and/or a combination of an acryloyl-containing photopolymerizable low-molecular substance or a combination of polyene and thiol is blended with (B) a radical reaction type photopolymerization initiator having mainly an absorption range in an ultraviolet zone at 300-450nm wavelength as an photopolymerization initiator, (C) an organic peroxide-based substance having 50-90 deg.C one hour half-life temperature and/or an azo compound-based substance having 40-70 deg.C one hour half-life temperature as a radical polymerization initiator, (D) a storage stabilizer and (E) >=10wt.% based on total amounts of the composition of pigment as a mixed material to give the aimed composition which is made into a coating film having <=5mm thickness or molded article and irradiated with ultraviolet light and cured. |
