Sheet for heat transference and method for using the same

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.

What is claimed is: .[.1. 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: 
     
        type, color of the sheet, and recording initiating position..]..Iadd.4.  A heat transfer recording process which performs printing by a dot-shaped heating means on a laminate of (a) a heat transfer sheet comrprising a base sheet and a heat transfer layer on said base sheet, said layer including a heat transferable dye and a binder of a synthetic resin, and (b) a dye-receiving sheet to be used in combination with the heat transfer sheet, said dye-receiving sheet having on a front surface thereof a dye-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: preparing said dye-receiving sheet as a sheet having a detection mark including physically detectabIe information and preliminarily provided on a back surface thereof opposite said front surface having said receptive layer;   feeding said dye-receiving sheet into a printer;   reading said information of the detection mark by means of reading means;   conveying said dye-receiving sheet to a print starting position of the printer only when the dye-receiving sheet is determined to be adequate on the basis of the information thus read by said reading means;   1aminating said heat transfer sheet with said dye-receiving sheet; and   carrying out printing by said dot-shaped heating means. .Iaddend..Iadd.5. The heat transfer recording process according to claim 4, wherein said detection mark comprises information for distinguishing the front and back surfaces of the dye-receiving sheet. .Iaddend..Iadd.6. The heat transfer recording process according to claim 4, wherein said detection mark comprises information which is readable magnetically. .Iaddend..Iadd.7. The heat transfer recording process according to claim 4, wherein said detection mark comprises information which is readable optically. .Iaddend..Iadd.8. The heat transfer recording process according to claim 4, wherein said detection mark comprises information which is readable   
     
     
        mechanically. .Iaddend..Iadd.9.  The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a direction of the dye-receiving sheet. .Iaddend..Iadd.10. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a residual amount of the dye-receiving sheet. .Iaddend..Iadd.11. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of relative positions between the heat transfer sheet and the dye-receiving sheet. .Iaddend..Iadd.12. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a grade of the dye-receiving sheet. .Iaddend..Iadd.13. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a type of the dye-receiving sheet. .Iaddend..Iadd.14. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a color of the dye-receiving sheet. .Iaddend..Iadd.15. The heat transfer recording process according to claim 4, wherein said detection mark comprises information of a recording initiating position. .Iaddend.
