Abstract
Abstract PCT No. PCT/JP84/00329 Sec. 371 Date Feb. 26, 1985 Sec. 102(e) Date Feb. 26, 1985 PCT Filed Jun. 26, 1984 PCT Pub. No. WO85/00322 PCT Pub. Date Jan. 31, 1985.The present invention relates to a sublimation ink ribbon capable of printing on a printing paper a still picture image of various kinds of picture images such as a picture image shot by a video camera, a television picture image and the like. At least the surface of its sublimation ink layer is made of a layer containing a sublimation dye whose solubility relative to methyl ethyl ketone is not higher than 2.5g/100 ml or a layer in which a sublimation dye having a solubility higher than 2.5g/100 ml is mixed such that a ratio (P/B) of a weight P of the sublimation dye relative to a weight B of a binder is not higher than 0.5. Thus, it is possible to reduce the under layer soil characteristics.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
66 words
A sublimation ink ribbon consisting of a heat-resisting base material and an ink layer coated on at least one surface thereof and formed by mixing at least a sublimation dye and a binder, characterized in that at least the surface of said ink layer is made of a layer containing a sublimation dye whose solubility in methyl ethyl ketone is not higher than 2.5 g/100 ml.
Claim 2
Dependent Claim
66 words
A sublimation ink ribbon consisting of a heat-resisting base material and an ink layer coated on at least one surface thereof and formed by mixing at least a sublimation dye and a binder, characterized in that at least the surface of said ink layer is made of a layer containing a sublimation dye whose solubility in methyl ethyl ketone is not higher than 2.5 g/100 ml.
Claim 3
Dependent Claim
123 words
A sublimation ink ribbon consisting of a heat-resisting base material and an ink layer coated on at least one surface thereof and formed by mixing at least a sublimation dye and a binder, characterized in that the surface of said ink layer is made of a layer which consists of a first sublimation dye whose solubility relative to methyl ethyl ketone is not higher than 2.5 g/100 ml and a second sublimation dye whose solubility relative to said methyl ethyl ketone is higher than 2.5 g/100 ml, said second sublimation dye being present in an amount such that the ratio (P/B) of the weight P of said second sublimation dye relative to the weight B of said binder is not higher than 0.5.
Claim 4
Dependent Claim
123 words
A sublimation ink ribbon consisting of a heat-resisting base material and an ink layer coated on at least one surface thereof and formed by mixing at least a sublimation dye and a binder, characterized in that the surface of said ink layer is made of a layer which consists of a first sublimation dye whose solubility relative to methyl ethyl ketone is not higher than 2.5 g/100 ml and a second sublimation dye whose solubility relative to said methyl ethyl ketone is higher than 2.5 g/100 ml, said second sublimation dye being present in an amount such that the ratio (P/B) of the weight P of said second sublimation dye relative to the weight B of said binder is not higher than 0.5.
Claim 5
Dependent Claim
70 words
A sublimation ink ribbon consisting of a heat-resisting base material and an ink layer coated on at least one surface thereof and formed by mixing at least a sublimation dye and a binder, characterized in that said ink layer is formed as a multilayer having an uppermost layer thereof formed of a layer containing a sublimation dye whose solubility in methyl ethyl ketone is not higher than 2.5 g/100 ml.
