Document Type and Number:
WIPO Patent Application WO/2014/003173
Kind Code:
A1
Abstract:
[Problem] To provide an active energy ray curing-type adhesive agent composition which is reliable and exhibits excellent gap filling properties. Moreover, when the composition is adhered to an article such as the surface protection layer of an image display device or the display screen or touch panel of an image display unit, air bubbles do not form on the interface, air bubbles do not form or peeling does not occur even when left standing for a long period of time in high temperature and high humidity conditions, and the composition does not become white. [Solution] An active energy ray curing-type adhesive agent composition containing the following components (A) and (B). Component (A) is a hydroxyl group-containing polymer in which a macromonomer having an ethylene unsaturated group at a terminal serves as a monomer (a1) of an essential structural monomer unit, the glass transition temperature of a homopolymer of the macromonomer being -100°C or higher and lower than 30°C. Component (B) is a compound having an ethylene unsaturated group.
