Document Type and Number:
WIPO Patent Application WO/2018/043624
Kind Code:
A1
Abstract:
A water-dispersed acrylic adhesive composition which is obtained by dispersing core-shell structure acrylic copolymer particles in an aqueous medium, each of said acrylic copolymer particles having a core layer (A) that contains an acrylic polymer (A) and a shell layer (B) that contains an acrylic polymer (B). This water-dispersed acrylic adhesive composition is characterized in that: the acrylic polymer (B) has a glass transition temperature of 30°C or higher; and the glass transition temperature of the acrylic polymer (A) is lower than the glass transition temperature of the acrylic polymer (B).
