Patent ID: 8715784

Claim:
A method for producing an optical layered body, comprising applying a coating composition on a light-transmitting substrate, wherein the coating composition comprises an urethane (meth)acrylate having a weight-average molecular weight of 6000 to 50,000 and having four or less functional groups, a (meth)acrylate having a weight-average molecular weight of 1000 or less, and a solvent that solubilizes or swells the light-transmitting substrate, forming an infiltration layer, in which a material forming the light-transmitting substrate and the (meth)acrylate are blended together, forming a coat on the infiltration layer, and forming a hard-coating layer and a cushioning layer by curing the infiltration layer and the coat, wherein said cushioning layer and said hard-coating layer is formed with a gradual change in the material characteristics of said cushioning layer and said hard-coating layer, and a hard coat layer which is composed of said hard-coating layer and said cushioning layer is also formed with a gradual change in the material characteristics of said cushioning layer and said hard-coating layer with the light-transmitting substrate.
