LAMINATE, METHOD FOR SEPARATING LAMINATE, AND METHOD FOR EVALUATING SEPARATION LAYER

摘要

This laminate (1) is obtained by sequentially laminating, in the following order, a substrate (11), an adhesive layer (14), a separation layer (16) that changes in properties by absorbing light, and a support plate (12). The optical density of the separation layer (16) is set to a value from 0.2 to 1.0 (inclusive). The present invention also comprises: a method for separating the laminate (1), which comprises a step for evaluating the optical density of the separation layer (16); and a method for evaluating a separation layer.
