Patent ID: 8801888

Claim:
A production process for a decorative sheet comprising a step in which a primer layer is formed on a releasing film having a smooth surface, a step in which a design layer is formed on the above primer layer, a step in which the primer layer and the design layer are transferred on a base material, a step in which the releasing film on the base material is peeled off, a step in which an ionizing radiation curable resin composition is laminated on the primer layer formed on the base material and a step in which the above ionizing radiation curable resin composition is cross-linked and cured to form a surface protective layer, wherein it further comprises a roughening treatment step in which a ten point average roughness RzJIS on a rear face of the decorative sheet and a thickness T of the base material are controlled to satisfy the following equation (I) and in which an arithmetic average roughness Ra on the rear face and a thickness T of the base material are controlled to satisfy the following equation (II): T× 0.30 ≧Rz JIS (I) T× 0.20 ≧R≧T× 0.005 (II).
