Abstract

The present invention relates to an active energy beam-curable adhesive composition having excellent adhesive power under high temperature and high humidity conditions and causing little coloration even when used for a long period of time. The active energy beam-curable adhesive composition of the present invention comprises (A) 5 to 50 weight % of a urethane (meth)acrylate having a polyester or polycarbonate skeleton, (B) 5 to 95 weight % of a compound having one (meth)acryloyl group represented by formula (1) below or / and formula (2) below, and as necessary (C) 0 to 85 weight % of an ethylenically unsaturated group-containing compound, 5 to 30 weight % of methacrylate compound being contained in the total amount of components (A) to (C). In formulae (1) and (2), R 1 and R 3 denote a hydrogen atom or a methyl group, R 2 and R 4 denote a halogen atom or a hydrocarbon group that has 10 or less carbons and does not have a hydrogen atom on the ±-position carbon atom, and m and n denote an integer of 1 to 5.

Description

technical field [0001] The present invention relates to an active energy ray-curable adhesive composition capable of bonding various substrates by irradiation with active energy rays such as electron beams and ultraviolet rays. [0002] The composition of the present invention is suitable for lamination and bonding of thin-layer coatings such as plastic films or plastic sheets of optical parts, and is suitable for use in liquid crystal display elements, EL (electroluminescence) display elements, projection display elements, The manufacture of various optical films or sheets of FED (field emission display) display elements, plasma display elements, etc. is well applied to these technical fields. Background technique [0003] Conventionally, the dry lamination method has been mainly used in lamination between thin-layer coverings such as plastic films or sheets, or between thin-layer coverings such as plastic films and sheets and thin-layer coverings of other materials, that i...
