PROBLEM TO BE SOLVED: To provide an active energy ray-curable adhesive for polarizing plates, having a high curing rate, a good wetting property and adhesiveness to a polyvinyl alcohol-based polarizing film and various protective films, retardation films and optical compensation films in producing a polarizing plate, having low viscosity and good workability, free from generation of uneven adhesion, and exhibiting high adhesive force, high durability, high water resistance and excellent transparency.SOLUTION: There is provided an active energy ray-curable adhesive including 45-95 wt.% of an N-hydroxyalkyl (meth)acrylamide, 4-54 wt.% of an N, N-dialkylacrylamide and 0.5-20 wt.% of a linear compound and/or branched compound having two or more vinyl groups on terminals or side chains. A polarizing film is bonded to a protective film, a retardation film or an optical compensation film with the adhesive, and the adhesive is cured by active energy ray irradiation. |
