ADHESIVE AGENT, ADHESIVE AGENT FOR OPTICAL MEMBER, OPTICAL MEMBER HAVING ADHESIVE LAYER ATTACHED THERETO, IMAGE DISPLAY DEVICE, ACTIVE-ENERGY-RAY- AND/OR HEAT-CURABLE ADHESIVE AGENT COMPOSITION, AND ADHESIVE AGENT COMPOSITION

摘要

Disclosed is an adhesive agent produced by curing an adhesive agent composition [I] with an active energy ray and/or heat, wherein the adhesive agent composition [I] comprises an acrylic resin (A), an aromatic compound (B) having one ethylenically unsaturated group, and an ethylenically unsaturated compound (C) having at least two ethylenically unsaturated groups, and wherein the adhesive agent is characterized in that the content of the component (B) is 3 to 300 parts by weight relative to 100 parts by weight of the component (A) and the ratio (mol%) of the content of the component (B) to the total content of the components (B) and (C) is more than 50 mol%. The adhesive agent enables the production of a liquid crystal display device in which an adhesive layer produced by curing the adhesive agent with an active energy ray and/or heat can have excellent handling properties (tack) and optical properties (haze), an optical laminate (particularly an optical member such as a polarizing plate) can be adhered to a glass substrate satisfactorily under high-temperature high-humidity environments, no foaming or detachment occurs between the adhesive agent layer and the glass substrate, and unevenness in color or leakage of light does not occur.
