PURPOSE:To provide a transfer product of fresh color tone and high rigidity by forming on a substrate sheet, such as (processed) paper and cellophane, a pattern layer including a binder and a colorant which has been prepared by pretreating a colorant poor in thermal transfer property with a specified alkali agent. CONSTITUTION:On a substrate sheet made of (processed) paper, cellophane, synthetic resin film, or the like, there is formed a single- or multi-color pattern layer by use of an ink or composition consisting mainly of a binder (e.g. ethyl cellulose) and a thermally transferable colorant which has been prepared by pretreating a colorant poor in thermal transfer property with an alkali agent (e.g. NaOH) for engancing the thermal transfer property of the colorant. This constitution enables the colorants which have rarely been used to be applicable to sublimation transfer process, and broadens the range of use of substrates onto which patterns are transferred. |
