PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR DECORATING PANEL, PRESSURE-SENSITIVE ADHESIVE SHEET AND DECORATING PANEL

摘要

PURPOSE: An adhesive composition for a decorative panel, adhesive sheet, and the decorative panel are provided to prevent the exfoliation phenomenon of the decorative panel during a processing or constructing process of the decorative panel. CONSTITUTION: An adhesive composition for a decorative panel contains the following: an acrylic resin having the weight average molecular weight over 1,000,000; an aziridine based polyfunctional cross-linking agent; and an epoxy-based coupling agent. The acrylic resin is a polymer of a monomer compound including a (meth)acrylic acid ester monomer and a monomer with a cross-linkable monomer. The cross-linkable monomer is a hydroxyl-containing monomer, a carboxy-containing monomer, or a nitrogen-containing monomer. An adhesive sheet(10) contains an adhesive layer(11) containing a cured product of the adhesive composition.
