An active energy ray curable adhesive composition, a polarizing plate, an optical film, and an image display device capable of forming an adhesive layer which improves the adhesion between a polarizer and a transparent protective film layer and has improved heat resistance and water resistance. (Solution) A component (A) which is a vinylamide compound represented by the following general formula (1), and And (B) a compound having two or more ethylenically unsaturated groups having radical polymerizability in one molecule and having a molecular weight of 1,000 or less. (In the formula (1), R 1 and R 2 are each a hydrogen atom or a monovalent hydrocarbon group having 1 to 6 carbon atoms, and R 1 and R 2 may be the same or different and may form a cyclic structure in which R 1 and R 2 are connected do) |
