    摘要: A photocurable pressure-sensitive adhesive composition, a photocurable pressure-sensitive adhesive layer, and a photocurable pressure-sensitive adhesive sheet including a support and such a photocurable pressure-sensitive adhesive layer formed on at least one side of the support are provided. The photocurable pressure-sensitive adhesive composition can form an adhesive layer that has sufficient initial adhesive strength through the process of drying and cross-linking without having any adhesive protruding at normal temperatures and pressures, hardens easily with light irradiation, and has a high peeling resistance. The photocurable adhesive composition contains a graft polymer that graft-polymerizes a monomer containing a cyclic ether group to a (meth)acrylic polymer and a cationic photopolymerization initiator. The photocurable adhesive layer and the photocurable adhesive sheet are prepared by using said photocurable adhesive composition.

    摘要: A finely divided, cationic, aqueous polymer dispersion, obtained by (I) solution polymerizing a first mixture containing (a) 15-40% by weight of a mixture of (a1) a (meth)acrylate and (a2) a (meth)acrylamide, (b) 40-85% by weight of styrene, (c) 0.5-5% by weight of an ethylenically unsaturated monomer, and (d) 0-20% by weight of a nonionic, ethylenically unsaturated monomer differing from (b); (II) adding water; and (III) emulsion polymerizing a second monomer mixture containing (i) 0-29% by weight of styrene, (ii) 50-100% by weight of a C1- to C18-(meth)acrylate, (iii) 0-30% by weight of a vinyl ester of a C1-C30-carboxylic acid, and (iv) 0-30% by weight of a nonionic ethylenically unsaturated monomer differing from (i), (ii), and (iii), wherein at least one of the solution and emulsion polymerizing are performed in the presence of 0-10% by weight of a regulator.
