Abstract
The present invention provides a method for producing a molded body, having the step 1 of applying a composition containing an alicyclic urethane (meth)acrylate to a thermoplastic resin substrate to obtain a coated material, the step 2 of irradiating the obtained coated material with an active energy ray to cure the composition, obtaining a laminated material having a cured product layer obtained from the cured composition, and the step 3 of subjecting the obtained laminated material to bending processing to obtain a molded body, wherein the alicyclic urethane (meth)acrylate has a structure having an alicyclic structure represented by the formula (A), and a group having two or more (meth)acryloyl groups represented by the formula (B), and further has a polymerizable double bond equivalent of 100 to 1,000 g/mol.
