ABSTRACT:
A sheet for sublimation transfer has an ink layer formed one side of a material sheet. A sublimation transfer ink forming the ink layer contains a binder which does not melt onto a printing medium, such as a printing paper, to which an image is transferred, and will not cause transfer of dyes to the backside of the sheet even when the sheet is rolled and placed in relatively high temperature environment for a long period of time. The binder is composed of vinyl acetal group (X), vinyl alcohol group (Y) ,and vinyl acetate group (Z) as expressed by the following formula (I): ##STR1## wherein R of said polyvinyl acetal resin is C.sub.n H.sub.2n+1, where n is zero or a positive integer greater than or equal to 4.
