Laminated bodies and their manufacturing methods, as well as component assemblies

Abstract

This invention provides a laminate with excellent re-peelability and interlayer adhesion within a short time after bonding, a method for manufacturing the laminate, and a component assembly. The laminate comprises a substrate treated with active energy rays and a cured layer of a moisture-curing polyurethane hot-melt resin composition, wherein the moisture-curing polyurethane hot-melt resin composition contains a urethane prepolymer (i) having isocyanate groups, the urethane prepolymer (i) being made from a polyol (A) and polyisocyanate (B), wherein the polyol (A) is composed of crystalline polyester polyol (a1) and amorphous polyester polyol (a2) as essential components, and the α value represented by the following formula (1) is in the range of 8.0 to 11.0.
