Method for producing cycloolefin resin-decorative molded article

A method for producing a decorated cycloolefin resin molded article, comprising:

• curing a gel coat composition containing a base resin and a thermal curing agent and polymerizing a cycloolefin polymerizable composition containing a radical generator at the same timing while the gel coat composition is in contact with the cycloolefin polymerizable composition, thereby obtaining the decorated cycloolefin resin molded article including a gel coat obtained by curing the gel coat composition and a cycloolefin resin layer obtained by polymerizing the cycloolefin polymerizable composition adhering to each other,
• wherein an amount of the thermal curing agent is 0.2 to 4 parts by mass relative to 100 parts by mass of the base resin, a content of a curing accelerator in the gel coat composition is 1 mass % or less, and the cycloolefin polymerizable composition further comprises an isocyanate compound and/or a polyfunctional acrylate compound,
• the isocyanate compound is at least one selected from the group consisting of 4,4′-methylenediphenyl diisocyanate, toluene-2,4-diisocyanate, 4-methoxy-1,3-phenylene diisocyanate, 4-isopropyl-1,3-phenylene diisocyanate, 4-chloro-1,3-phenylene diisocyanate, 4-butoxy-1,3-phenylene diisocyanate, 2,4-diisocyanate diphenyl ether, 1,4-phenylene diisocyanate, tolylene diisocyanate, xylylene diisocyanate, 1,5-naphthalene diisocyanate, benzidine diisocyanate, o-nitrobenzidine diisocyanate, 4,4′-dibenzyl diisocyanate, methylene diisocyanate, 1,4-tetramethylene diisocyanate, 1,6-hexamethylene diisocyanate, 1,10-decamethylene diisocyanate, 4-cyclohexylene diisocyanate, 4,4′-methylene bis(cyclohexyl isocyanate), 1,5-tetrahydronaphthalene diisocyanate, isophorone diisocyanate, hydrogenated 4,4′-methylenediphenyl diisocyanate, hydrogenated xylylene diisocyanate, and a polyurethane prepolymer prepared by reacting these diisocyanate compounds with a low molecular weight polyol or polyamine to be isocyanate terminated, and
• the polyfunctional acrylate compound is at least one selected from the group consisting of ethylene glycol dimethacrylate, triethylene glycol dimethacrylate, trimethylolpropane trimethacrylate, and neopentyl glycol dimethacrylate.
