PURPOSE:To obtain an extremely excellent anti-blocking property, by providing a layer of a material obtained by cross-linking and hardening a specified polysiloxane having a terminal vinyl group by a peroxide in a specified thickness on the side on which heat is applied. CONSTITUTION:The layer of a material obtained by cross-linking and hardening a polysiloxane having a terminal group with eta=2-1,000,000 of formula (1), (2) or (3), wherein A is -CH=CH2, Me is methyl and Ph is phenyl, be a peroxide is provided on the side on which heat is applied. The peroxide is preferably a diacyl peroxide such as benzoyl peroxide. The thickness of the layer in the hardened state is set to be 0.02-1mum. If the thickness is less than 0.02mum, a uniform effect can not be expected, whereas if the thickness is more than 1mum, the sensitivity of the ink sheet is lowered. Accordingly, blocking can be prevented from occurring where the ink sheet is rolled or stacked. |
