Poly(vinyl acetal) resin composition, adhesive sheet, interlaminar filling material for touch panel, and laminate

Abstract

The present invention aims to provide a polyvinyl acetal resin composition that is excellent in thermal stability and moldable by an extrusion method and can exhibit a high storage modulus even under high temperature, an adhesive sheet prepared from the polyvinyl acetal resin composition, an interlayer filling material for a touch panel prepared from the polyvinyl acetal resin composition, and a laminate produced using the interlayer filling material for a touch panel. The present invention relates to a polyvinyl acetal resin composition containing: a polyvinyl acetal; a photoradical polymerization initiator; and a monomer or oligomer having a radical polymerizable double bond.
