Ink sheet for thermal transfer recording

Abstract

Abstract 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 active radiations in a predetermined 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 vinyl group with eta=2-1,000,000 of general formula (1), (2), or (3), wherein A is -CH=CH2, Me is methyl and Ph is phenyl, by active radiations is provided on the side on which heat is applied. UV rays, electron rays or the like can be used as the active variations. When UV rays are used, a photo-reaction initiator or a sensitizer is used together. The thickness of the layer in the hardened state is 0.02-1mum. If the thickness is less than 0.02mum, a uniform effect can not be expected, whereas if the thickness if 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.
