METHOD FOR PRODUCING MULTILAYER SHEET, AND MULTILAYER SHEET

WIPO Patent Application WO/2012/005221

A1

Disclosed is a method for producing a multilayer sheet, wherein at least two active energy ray-curable resin layers are collectively polymerized by irradiation of an active energy ray. The active energy ray-curable resin layers include an active energy ray-curable resin layer (A), which is formed from a resin composition (A) that contains an active energy ray-curable acrylic monomer, and an active energy ray-curable resin layer (B), which is formed from a resin composition (B) that contains an active energy ray-curable acrylic monomer and a solid component that is composed of a urethane polymer. The solid component that is composed of a urethane polymer has a weight average molecular weight of 10,000 or more, and the solid component amount (the polymerized fraction) of the solid component that is composed of a urethane polymer in the resin composition (B) is 35% by mass or more. The solid component amount (the polymerized fraction) of two adjacent active energy ray-curable resin layers is set to be 50% by mass or more in total. Consequently, the method for producing a multilayer sheet exhibits high productivity and is capable of providing each layer with a desired function.
