Kind Code:
A1
Abstract:
The present invention relates to the useful improvement of an adhesive composition that can be used for multistage curing and to the use thereof. The adhesive composition contains an acrylic resin (A) and a photoinitiator (B). The acrylic resin (A) is a polymerization product of a copolymer component (a). The copolymer component (a) contains an alkyl acrylate (a1) that has a glass transition temperature of -30 to 50°C when a homopolymer is formed and an alkyl methacrylate (a2) that has a glass transition temperature of -10 to 120°C when a homopolymer is formed. The total content of alkyl acrylate (a1) and alkyl methacrylate (a2) is 5 wt% or more relative to 100 wt% of copolymer component (a). Application examples of the adhesive composition relate to an adhesive, an adhesive sheet, an adhesive sheet with a release film, a laminate for an image display device, a curved image display device, and an adhesive composition for a curved optical member.
