Abstract

Disclosed is a curable resin composition for surface protection capable of forming a protection film, which is environmental friendly while having good adhesion strength and can be easily removed in a film form in water without leaving any adhesive residue, on a member to be processed. Also disclosed are a photocurable adhesive using such a curable resin composition, a method for temporarily fixing a member, and a method for separating a protection film. Specifically disclosed is a curable resin composition for surface protection, which is characterized by containing a polyfunctional (meth)acrylate (A), a monofunctional (meth)acrylate (B), and a resin (C) having a cyclopentadiene skeleton. Also specifically disclosed is a curable resin composition for surface protection, which is characterized by containing a polyfunctional (meth)acrylate (A), a monofunctional (meth)acrylate (B), a resin (C) having a cyclopentadiene skeleton, and a photopolymerization initiator (D). Further specifically disclosed is a curable resin composition for surface protection, which is characterized by containing a polyfunctional (meth)acrylate (A), a monofunctional (meth)acrylate (B), a resin (C) having a cyclopentadiene skeleton, a photopolymerization initiator (D), and a polar organic solvent (E).

Description

technical field

[0001] The present invention relates to a surface protective film for protecting the processed member from cutting chips and the like when processing various members, and for protecting the undesired coating when the processed member is painted or printed with ink or the like. Or a surface protective film (hereinafter also referred to as "protective film") for temporary fixing of printed parts. It also relates to a curable resin composition suitable for the surface protection film, and a surface protection method for protecting the surface of a member to be processed using an adhesive composed of the curable resin composition.

[0002] More specifically, the present invention relates to a method for peeling a protective film covering a processed member when peeling the member, and a photocurable adhesive suitable for the use. It also relates to a temporary fixing method of a processed member, that is, bonding the processed member to a base material, after proc...
