Title:
ACTIVE ENERGY RAY CURABLE RESIN COMPOSITION, SEAL MATERIAL AND BUFFER MATERIAL CONSISTING OF CURED ARTICLE THEREOF
Document Type and Number:
Japanese Patent JP2017179092
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an active energy ray curable resin composition having flowability and thixotropic property suitable for a CIP method, excellent in coatability and shape accuracy capable of providing a seal material with fine line width and forming a cured article having high buffer and vibrationproof property.SOLUTION: There is provided an active energy ray curable resin composition containing a photopolymerizable oligomer (A), a photopolymerizable monomer (B), a photoinitiator (C) and a thixotropy adding agent (D), the photopolymerizable oligomer (A) is urethane (meth)acrylate having mass average molecular weight of 5000 or more, the photopolymerizable monomer (B) contains a phenoxy phenyl (meth)acrylate or phenoxybenzyl (meth)acrylate compound (b1) of 20 to 60 mass% based on whole mass of the photopolymerizable monomer (B). There is provided an active energy ray curable resin composition having content of B of 80 to 99 mass% based on total mass of A+B and the thixotropy adding agent (D) is 1 to 40 pts.mass based on 100 pts.mass of (A+B+C).SELECTED DRAWING: None
