摘要：
The present invention realizes forming of a hard coat having excellent leveling without lowering physical properties. An information signal portion is formed on a substrate. A light transmitting sheet is bonded to the substrate with a bonding layer disposed therebetween to form a light transmitting layer. There is obtained a composition for hard coat by adding a low molecular-weight reactive diluent to a solvent-type hard coat agent. The composition for hard coat is coated on the light transmitting layer uniformly by a spin coating method. The coated composition for hard coat is cured to be a hard coat.
