Abstract
Abstract A heat transfer sheet having a heat transfer layer on one surface of a base sheet, said heat transfer layer being formed of a material containing a dye substantially dissolved in a binder with a weight ratio of the dye to the binder (dye/binder ratio) of 0.3 or more, and said base sheet having a heat-resistant slipping layer provided on the surface on which the heat transfer layer is not provided. A heat transferable sheet to be used in combination with the heat transfer sheet, comprising a receptive sheet having (a) a base sheet and (b) a receptive layer for receiving the dye migrated from the above-mentioned heat transfer sheet on heating, said receptive sheet having an intermediate layer provided between the base sheet and the receptive layer.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A heat transfer recording process which performs printing by a dot-shaped heating means on a laminate of (a) a heat transfer sheet having a heat transfer layer of a substance which is softened, melted or gasified by heating formed on a base sheet and (b) a dye-receiving sheet to be used in combination with the heat transfer sheet, having a receptive layer for receiving a dye migrated from the heat transfer sheet upon heating to form an image on the dye-receiving sheet, said process comprising: reading a physically detectable detection mark formed on the dye-receiving sheet; laminating the heat transfer sheet with the dye-receiving sheet in accordance with the information thus read; and carrying out printing.
Claim 2
Dependent Claim
