How to use machinability improving film, laminate, and machinability improving film

摘要

PROBLEM TO BE SOLVED: To provide a machinability-improving film or the like capable of obtaining excellent machinability and durability by adhering a resin plate, a resin film or the like through a machinability-improving layer. SOLUTION: A machinability improving film or the like including a base material, a machinability improving layer containing an active energy ray-curable component and a crosslinkable component, and attached to a resin plate. The adhesive strength (P1) before irradiation with active energy rays is 1 N / 25 mm or more, and the adhesive strength (P2) after irradiation with active energy rays is 10 N / 25 mm or more with respect to the machinability improving layer. Yes, and the gel content of the machinability improving layer after irradiation with active energy rays is 75% or more. [Selection diagram] Fig. 1
