Abstract: An active-energy-ray-curable adhesive composition comprises at least one or more radical polymerizable compounds. At the time of defining a total amount of the radical polymerizable compound(s) as 100% by weight, the composition comprises one or more alkyl (meth) acrylates (A) (each) having 10 to 20 carbon atoms in an amount of 15% or more by weight. The active-energy-ray-curable adhesive composition preferably comprises, as the alkyl (meth)acrylate(s) (A), an alkyl (meth)acrylate (A1) having 10 to 14 carbon atoms, and an alkyl (meth)acrylate (A2) having 15 to 20 carbon atoms. A ratio by weight of the component (A1) to the component (A2) (A1/A2) is preferably from 1.0/9.0 to 4.0/6.0.

Abstract: The present invention pertains to a polarizing film having a transparent resin layer on at least one side of a polarizer containing a polyvinyl alcohol-based resin, wherein the transparent resin layer has a thickness of 0.2 μm or more and is formed from a layer-forming material containing a polyvinyl alcohol-based resin having a saponification degree of 96 mol % or more, and wherein the combined total content of sodium acetate and potassium acetate contained in the transparent resin layer is less than 1 wt %. This polarizing film has crack-resistant properties, and can minimize degradation of the optical characteristics in a heating and humidifying test.
