ADHESIVE COMPOSITION, ADHESIVE SHEET, AND MANUFACTURING METHOD OF ADHESIVE
Document Type and Number:
Japanese Patent JP2019131638
Kind Code:
A
Abstract:
To provide an adhesive composition capable of forming an adhesive of which adhesive force is effectively reduced by irradiation of an active energy ray.SOLUTION: There is provided an adhesive composition forming an adhesive of which adhesive force is reduced by irradiation of an active energy ray, containing an acrylic polymer (A) having an active hydrogen group, a compound (B) having a carbon-carbon double bond and a functional group reacting with the active hydrogen group, adding the carbon-carbon double bond to the acrylic polymer (A) contributing to formation of the adhesive, and having mass change rate when heated at 90°C for 5 min. of 5% or less, and a crosslinking agent (C) having 2 or more functional groups reacting with the active hydrogen group. Equivalence of the carbon-carbon double bond obtained by the compound (B) based on the acrylic polymer (A) is 1.9 meq/g or more, or content of the compound (B) is 30 to 150 pts.mass based on 100 pts.mass of the acrylic polymer (A).SELECTED DRAWING: None
