Abstract
Abstract A thermal dye-transfer recording, image-receiving sheet, comprising a support having thereon an image-receiving layer containing a butyral resin for receiving a transferred image from a coloring material-transferring sheet, is disclosed. In this image-receiving sheet, sharp recorded images can be obtained, and the images exhibit excellent storage stability and abrasion resistance.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
45 words
A recording system comprising: a. a coloring material-transferring sheet containing a heat-sublimable dye; and b. a thermal dye-transfer recording, a heat-sublimable dye-receiving sheet comprising a support having thereon a heat-sublimable dye-receiving layer containing a butyral resin for receiving heat-sublimable dye from the coloring material-transferring sheet.
Claim 2
Dependent Claim
45 words
A recording system comprising: a. a coloring material-transferring sheet containing a heat-sublimable dye; and b. a thermal dye-transfer recording, a heat-sublimable dye-receiving sheet comprising a support having thereon a heat-sublimable dye-receiving layer containing a butyral resin for receiving heat-sublimable dye from the coloring material-transferring sheet.
Claim 3
Dependent Claim
37 words
A recording system as claimed in claim 1, wherein said butyral resin is coated on said support in an amount of from 2 to 15 g per square meter of said support on a dry weight basis.
Claim 4
Dependent Claim
22 words
A recording system as claimed in claim 1, wherein said butyral resin is a reaction product of polyvinyl alcohol and butyl aldehyde.
Claim 5
Dependent Claim
22 words
A recording system as claimed in claim 3, wherein said butyral resin has a degree of butyralization of at least 50 mol%.
Claim 6
Dependent Claim
23 words
A recording system as claimed in claim 4, wherein said butyral resin has a degree of butyralization of from 55 to 75 mol%.
Claim 7
Dependent Claim
32 words
A recording system as claimed in claim 3, wherein the unsaponified vinyl acetate group content in said butyral resin resulting from the starting polyvinyl alcohol is controlled to 20 mol% or less.
Claim 8
Dependent Claim
32 words
A recording system as claimed in claim 6, wherein the unsaponified vinyl acetate group content in said butyral resin resulting from the starting polyvinyl alcohol is controlled to 10 mol% or less.
Claim 9
Dependent Claim
20 words
A recording system as claimed in claim 1, wherein said butyral resin is used in combination with a cross-linking agent.
Claim 10
Dependent Claim
28 words
A recording system as claimed in claim 8, wherein said cross-linking agent is used in an amount of 50% by weight or less based on said butyral resin.
Claim 11
Independent Claim
98 words
A method for obtaining a thermal dye-transferred recorded image comprising the steps of: a. superimposing (1) a coloring material-transferring sheet, comprising a substrate having coated thereon a coloring material, over (2) a thermal dye-transfer recording, heat-sublimable dye-receiving sheet, comprising a support having thereon a heat-sublimable dye-receiving layer containing a butyral resin, in such a manner that the coloring material coated on the substrate comes into contact with the heat-sublimable dye-receiving layer; and b. heating the substrate of the coloring material transferring sheet to selectively transfer at least a portion of the coloring material to the heat-sublimable dye-receiving layer.
Claim 12
Independent Claim
98 words
A method for obtaining a thermal dye-transferred recorded image comprising the steps of: a. superimposing (1) a coloring material-transferring sheet, comprising a substrate having coated thereon a coloring material, over (2) a thermal dye-transfer recording, heat-sublimable dye-receiving sheet, comprising a support having thereon a heat-sublimable dye-receiving layer containing a butyral resin, in such a manner that the coloring material coated on the substrate comes into contact with the heat-sublimable dye-receiving layer; and b. heating the substrate of the coloring material transferring sheet to selectively transfer at least a portion of the coloring material to the heat-sublimable dye-receiving layer.
Claim 13
Dependent Claim
22 words
A method as claimed in claim 10, wherein the coloring material is colored itself and is solid or semi-solid at room temperature.
Claim 14
Dependent Claim
40 words
A method as claimed in claim 10, wherein a thermal recording head is used to heat the substrate of the coloring material transferring sheet to selectively transfer at least a portion of the coloring material to the heat-sublimable dye-receiving layer.
Claim 15
Dependent Claim
36 words
A method as claimed in claim 10, wherein the butyral resin is coated on the support in an amount of from 2 to 15 g per square meter of the support on a dry weight basis.
