The radical polymerizable compounds comprise a component A having a log Pow of ?2 to 2, and a component B having a log Pow more than 7, each of these log Pow values representing an octanol/water distribution coefficient. The component A preferably comprises at least one nitrogen-containing monomer selected from the group consisting of (meth)acrylamide derivatives, amino-group-containing monomers, and nitrogen-containing and heterocycle-containing vinyl monomers. The component B preferably comprises an alkyl (eth)acrylate having 18 to 20 carbon atoms.

  • Patent number: 10901129
    Abstract: A polarizing film, wherein transparent protective films are laid, respectively, on/over both surfaces of a polarizer to interpose an adhesive layer (a) and an adhesive layer (b), respectively, between both the surfaces and the transparent protective films. The adhesive layer (a) has a glass transition temperature of ?60° C. or higher and lower than 40° C. The adhesive layer (b) has a glass transition temperature of 40° C. or higher. The adhesive layer (a) is a layer formed in the form of a cured product layer yielded by radiating an active energy ray to an active-energy-ray-curable adhesive composition (a). The active-energy-ray-curable adhesive composition (a) comprises at least one or more radical polymerizable compounds, and when a total amount of the radical polymerizable compound(s) is defined as 100% by weight, one or more alkyl (meth)acrylates (A) (each) having 10 to 20 carbon atoms are comprised in a proportion of 15% or more by weight.

  • Patent number: 10858553
    Abstract: A polarizing film, wherein transparent protective films are laid, respectively, on/over both surfaces of a polarizer to interpose an adhesive layer (a) and an adhesive layer (b), respectively, between both surfaces of a polarizer, and transparent protective films. The adhesive layer (a) on/over one of both the surfaces has a glass transition temperature of ?60° C. or higher and lower than 40° C. The adhesive layer (b) on/over the other surface has a glass transition temperature of 40° C. or higher. The adhesive layer (a) is a layer formed in the form of a cured product layer yielded by radiating an active energy ray to an active-energy-ray-curable adhesive composition (a). The active-energy-ray-curable adhesive composition (a) comprises, as radical polymerizable compounds, a component A having a logPow of ?2 to 2, and a component B having a logPow more than 7, these logPow values being each an octanol/water distribution coefficient.
