A thermo-transfer sheet is composed of a base film and an ink layer to be transferred having a softening point of more than 120.degree. C. A label is formed by the thermo-transfer sheet and provided with an image ink layer formed on a thermo-transfer image receiving sheet through a temperature-sensitive adhesive layer and the image ink layer has a softening point of more than 120.degree. C. The thermo-transfer sheet and the thermo-transfer image receiving sheet are prepared and a temperature-sensitive adhesive layer is formed on at least one of the surface of the thermo-transfer sheet or the transfer ink layer of the thermo-transfer image receiving sheet. These sheets are laminated and the laminated sheets are heated by means of a thermal head to thereby transfer the image ink layer having a softening point of more than 120.degree. C. on the thermo-transfer image receiving sheet. According to these processes, a label such as bar code is manufactured with an excellent durability such as friction-proof property, solvent-proof property and heat-proof property.

Thermo-transfer sheet and label and manufacturing method of the same

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.

Image-receiving sheet

Heat transfer sheet

A thermal transfer sheet comprising a substratte film, a transferable ink layer formed on one surface side of the substrate film, and a back coating layer formed on the other surface side of the substrate film to be in contact with a thermal head, wherein the transferable ink layer comprises a heat-fusible ink capable of being melted under heating, and the back coating layer comprises a binder predominantly comprising polyparabanic acid.

Thermal transfer sheet

Sheet for heat transference

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 beat-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.

Thermo-transfer sheet

Sheet for heat transference and method for using the same

A thermal transfer sheet comprising a substrate film, a transferable ink layer formed on one surface side of the substrate film, and a back coating layer formed on the other surface side of the substrate film to be in contact with a thermal head, wherein the transferable ink layer comprises a heat-fusible ink capable of being melted under heating, and the back coating layer comprises a binder predominantly comprising polyparabanic acid.

A heat transfer sheet comprises a sheet for heat transfer recording which transfers ink on a base sheet onto a recording paper, said ink containing a compound represented by formula (I) shown below as a binder component:

A heat-sensitive transfer sheet comprising a substrate and a transfer layer formed on one surface of the substrate, wherein the transfer layer contains a coloring agent and, a compound having at least one atomic group --NHCO-- in each molecule as a binder.

Heat-sensitive transfer sheets

A transfer sheet comprising, in laminated combination, a substrate sheet and, provided thereabove, a coloring layer of desired pattern containing a coloring agent possessing heat transferability and a resist layer of a desired pattern containing a metal compound for resist printing and a binder, the metal compound having the capability of causing the coloring layer to lose its heat transferability, either of the coloring layer and the resist layer being nearer than the other to the substrate sheet. Because of the capability of the metal compound, the resist power is very great, whereby ample resist printing effect can be obtained with only an extremely thin resist layer.
