Patent ID: 8475891

Claim:
A embossed release paper comprising a paper base material, an ionizing radiation-cured resin layer, and a heat-cured silicone layer stacked in that order, the embossed release paper having embosses, the ionizing radiation-cured resin layer being formed by curing an ionizing radiation-curable composition selected from the group consisting of a (meth)acryloyl group-containing acrylic copolymer (I) and (II), wherein the (meth)acryloyl group-containing acrylic copolymer (I) is a copolymer produced by reacting an epoxy group-containing copolymer (C) comprising (meth)acrylate monomer units (A) and epoxy group-containing (meth)acrylate monomer units (B) with (meth)acrylic acid, and the (meth)acryloyl group-containing acrylic copolymer (II) is a copolymer produced by reacting a copolymer comprising 35 to 80 parts by mass of a (meth)acrylic ester, 20 to 60 parts by mass of a glycidyl (meth)acrylic ester, and 0 to 30 parts by mass of another (meth)acrylic ester with 10 to 30 parts by mass of a (meth)acrylic acid.
