Abstract

Abstract A heat-sensitive transfer medium comprising a support, and a transfer layer comprising a protective resin layer, a metal deposition layer and an adhesive layer, said three layers being provided in that order from the supporting side. The transfer layer of the medium can be selectively transferred to a plain paper upon heating with a thermal head to give a transfer image having an excellent metallic luster.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 145 words
A method for producing print images having a metallic luster by use of a heat-sensitive transfer medium, which comprises the steps of: (a) preparing a heat-sensitive transfer medium comprising a support and a transfer layer on one side of said support wherein said transfer layer comprises a protective resin layer having a heat deformation temperature of at least 120° C., a metal deposition layer on said resin layer, and an adhesive layer over said metal deposition layer; (b) bringing said adhesive layer of said transfer layer into contact with a receiving medium; and (c) heating localized areas of said transfer layer by means of a thermal head which is brought into contact with the support of the transfer medium, thereby selectively transferring the heated areas of the transfer layer onto the receiving medium to form print images having a metallic luster on said receiving medium.
Claim 2
Independent Claim 145 words
A method for producing print images having a metallic luster by use of a heat-sensitive transfer medium, which comprises the steps of: (a) preparing a heat-sensitive transfer medium comprising a support and a transfer layer on one side of said support wherein said transfer layer comprises a protective resin layer having a heat deformation temperature of at least 120° C., a metal deposition layer on said resin layer, and an adhesive layer over said metal deposition layer; (b) bringing said adhesive layer of said transfer layer into contact with a receiving medium; and (c) heating localized areas of said transfer layer by means of a thermal head which is brought into contact with the support of the transfer medium, thereby selectively transferring the heated areas of the transfer layer onto the receiving medium to form print images having a metallic luster on said receiving medium.
Claim 3
Dependent Claim 45 words
The method of claim 1, wherein the thickness of the protective resin layer, the thickness of the metal deposition layer and the thickness of the adhesive layer are from 0.5 to 2 μm, from 10 to 100 nm and from 1 to 10 μm, respectively.
Claim 4
Dependent Claim 20 words
The method of claim 2, wherein the support is a resin film having a thickness of 2.5 to 9 μm.
Claim 5
Dependent Claim 19 words
The method of claim 1, wherein the adhesive layer is melted at a temperature of 70° to 100° C.
Claim 6
Dependent Claim 16 words
The method of claim 1, wherein the protective resin layer is directly provided on the support.
Claim 7
Dependent Claim 19 words
The method of claim 1, wherein a lubricant layer is interposed between the support and the protective resin layer.
Claim 8
Dependent Claim 14 words
The method of claim 1, wherein the protective resin layer is a matted layer.
Claim 9
Dependent Claim 29 words
The method of claim 1, wherein a sticking-preventive layer is provided on the back surface of the support which is to be brought into contact with a thermal head.
Claim 10
Dependent Claim 21 words
The method of claim 8, wherein the sticking-preventive layer comprises a fluorine-containing compound as a main component and a heat-resistant resin.
Claim 11
Dependent Claim 15 words
The method of claim 9, wherein the fluorine-containing compound is a fluorine-containing surface active agent.
Claim 12
Dependent Claim 15 words
The method of claim 10, wherein the fluorine-containing surface active agent is perfluoroalkylsulfonic acid salt.
Claim 13
Dependent Claim 22 words
The method of claim 11, wherein the perfluoroalkylsulfonic acid salt is one wherein the perfluoroalkyl group has 5 to 8 carbon atoms.
Claim 14
Dependent Claim 18 words
The method of claim 8, wherein the thickness of the sticking-preventive layer is from 0.05 to 3 μm.
