Title:
ACTIVE ENERGY RAY-CURABLE PEELABLE ADHESIVE COMPOSITION AND PEELABLE ADHESIVE SHEET
Document Type and Number:
Japanese Patent JP2019157127
Kind Code:
A
Abstract:
To provide an active energy ray-curable peelable adhesive composition that makes it possible to obtain an adhesive having excellent adhesiveness before and after active energy ray irradiation, and also excellent peelability (stain resistance and slight adhesiveness) after active energy ray irradiation.SOLUTION: An active energy ray-curable peelable adhesive composition contains an acrylic resin (A), a urethane (meth) acrylate compound (B), a crosslinker (C) and a photopolymerizable initiator (D), the acrylic resin (A) being an acrylic resin (A1) with an acid value of 1.5 mgKOH/g or less, the photopolymerizable initiator (D) being at least one of an α-amino alkylphenone photopolymerizable initiator (D1) and an acylphosphine oxide photopolymerizable initiator (D2).SELECTED DRAWING: None
