<P>PROBLEM TO BE SOLVED: To provide an optical pressure-sensitive adhesive composition, which is excellent in adhesive force not only to plastic materials but also to inorganic materials, durability such as heat resistance and moist heat resistance, and shear deformation ratio, and further which can produce a thick film type adhesive film since it is free from other solvents. <P>SOLUTION: The optical pressure-sensitive adhesive composition contains: 40-80 wt.% of a monofunctional urethane acrylate-based oligomer; 1-55 wt.% of an isobonyl (meth)acrylate first monofunctional diluted monomer; 1-55 wt.% of a second monofunctional diluted monomer having a glass transition temperature (Tg) of 1°C or higher and having an ethylene unsaturated group; and 0.1-5 wt.% of a free radical photoinitiator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
