PROBLEM TO BE SOLVED: To provide a self-adhesive having high self-adhesive force in a dicing process so that detachment and scattering of cut pieces of semiconductor elements etc., are suppressed, affording even articles to be processed having an activated surface, excellent light peelability and low staining properties in a pickup process; and to provide a self-adhesive film for dicing having a self-adhesive layer including the self-adhesive. SOLUTION: This radiation-curable self-adhesive composition includes a (meth)acrylic polymer and a multifunctional monomer, where the (meth)acrylic polymer is obtained by reacting a base polymer, having at least a 2-8C linear- or branched-alkyl group-containing (meth)acrylic monomer, a hydroxy group-containing (meth)acrylic monomer and a 14-18C linear-alkyl group-containing (meth)acrylic monomer as copolymerizable monomer components, with a radiation-reactive compound having a radiation-reactive carbon-carbon double bond in the molecule. The self-adhesive film for dicing has a self-adhesive layer including the self-adhesive. COPYRIGHT: (C)2011,JPO&INPIT |
