Title:
ACTINIC RADIATION CURABLE RESIN COMPOSITION CONTAINING POLYFUNCTIONAL ACRYLATE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2012/096330
Kind Code:
A1
Abstract:
The present invention provides a resin composition which serves as an adhesive for accurately fixing a component made of a material such as metal or plastic. This resin composition exhibits high initial adhesion to the material. In the durability tests including high-temperature and high-humidity test, the resin composition exhibits high holding power, and is rarely deformed even when heated under loading as well as when heated, thus inhibiting the movement of the part. An actinic radiation curable resin composition characterized by comprising (A) a polyfunctional acrylate compound having four or more (meth)acryloyl groups in the molecule, (B) a photocurable prepolymer, (C) a mono- or bi-functional (meth)acryloyl -containing monomer and (D) a photopolymerization initiator, said polyfunctional acrylate compound (A) being selected from the group consisting of (a1) glycerol derivatives, and linear or branched polymers thereof which each comprise ether skeletons as the connecting functional groups, (a2) trimethylolpropane derivatives, and linear or branched polymers thereof which each comprise ether skeletons as the connecting functional groups, (a3) monomeric pentaerythritol derivatives, and linear or branched polymers thereof which each comprise ether skeletons as the connecting functional groups, and (a4) dendrimers which contain ether or ester bonds and in which (meth)acryloyl groups are present at four or more terminals.
