PURPOSE: To improve the shortage of glossiness and also improve the film strength by coating one face of a substrate with a peeling layer comprising a replenished silicone compound curable with electron radiation of viscosity of 30-5000cps as main component.

CONSTITUTION: A peeling layer comprising as main component a silicone compound curable with electron radiation of viscosity of 30-5000cps, the average composition of which is represented by a formula I (R1a, R2b, R3c and R4d are organic radicals, R1=-CH3, R2=-OC1H21+1, R3=-CmH2m-Ph, and R4=-CnH2n -OCOC (R5)=CH2, and l=0W5, m=0W3, n=0W6 and R5=-H, -CH3, and Ph is phenyl. a, b, c and d satisfy following relationship c/a=0.2W1.8, c>b≥0, d=0.016W0.45 and 1.1<a+b+c+d<2.3), is formed at least on one face of a substrate. A peeling layer comprising a branched silicone compound curable by electron radiation is formed on the substrate and laminated closely on a base with a mirror face, and the laminate is cured by the emission of electron radiation in the closely laminated state, and then the base with the mirror face is peeled off.
