Patent ID: 8025940

Claim:
An optical laminate in a display comprising a transparent substrate and a hard coat layer provided on said transparent substrate, said hard coat layer being formed of a cured product of a composition comprising an ionizing radiation curing composition comprising pentaerythritol triacrylate or dipentaerythritol hexaacrylate, and a fluorine-modified urethane acrylate or a polydimethylsiloxane represented by the following formula (I): wherein: x and y represent positive integers; n is not less than 0; A represents a polyether-modified acryl group; the fluorine-modified urethane acrylate has a structure such that each hydrogen atom of urethane acrylate is substituted with a fluorine atom; the laminate is in roll form without any side tape between adjacent layers; the composition per se is curable and slippery so that when the laminate is wound into a roll, adhesion between the hard coat layer and the transparent substrate is suppressed; and the laminate is formed without including a silicone oil.
