  • Publication number: 20210317337
    Abstract: An active-energy-ray-curable adhesive composition comprises at least radical polymerizable compounds. 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.

  • Publication number: 20190136091
    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.
