摘要： A thermal transfer sheet which can prevent a kick and a scumming, and can form a photographic tone color image of high quality with a continuous tone image by sublimation transfer; a coating liquid for colorant layer to be used for forming the colorant layer of this thermal transfer sheet; a method for manufacturing this thermal transfer sheet; and image forming method employing this thermal transfer sheet. The problem is solved by a thermal transfer sheet (1) in which at least a colorant layer (3) is layered on a substrate sheet (2), wherein the colorant layer (3) contains a predetermined solvent, a colorant (10x) dispersible in the predetermined solvent, a dispersant, and a binder resin, and the dispersant being one or more selected from the group consisting of polyether-based dispersants, graft type polymer dispersants, acryl-based block type polymer dispersants, urethane-based polymer dispersants and azo-based dispersants.

摘要： A sublimation thermal transfer sheet having first, second, and third dye layers frame sequentially provided on a surface of a substrate in this order, and a back-face layer provided on another surface of the substrate. The first, second, and third dye layers contain an each individual sublimable dye and an each individual binder resin. One of the first and second dye layers further contains a releasing agent selected from a first group consisting of silicone oils, silicone-modified resins and phosphoric esters, and another dye layer further contains either one or both of at least a releasing agent selected from the first group and a cellulosic resin. The third dye layer (1) contains no releasing agent of the first group, or (2) contains the releasing agent at an amount of not more than 0.3% by weight based on the total weight of the solid content of the third dye layer.

摘要： A sublimation thermal transfer sheet and combination of a sublimation thermal transfer sheet and a transfer receiving article that meet the demand for increase in the density of a color image to be formed, that prevent decrease in the adhesiveness of a protective layer optionally formed on the color image, and that also have superior light resistance. In a sublimation thermal transfer sheet including a substrate and yellow, magenta, and cyan colorant layers provided on one surface of the substrate, the yellow and the above magenta colorant layers each contain a predetermined amount of a high-ε sublimable dye having a molar absorption coefficient of not less than 50000 and a molecular weight of not more than 650, and the cyan colorant layer contains a predetermined amount of a high-ε sublimable dye having a molar absorption coefficient of not less than 20000 and a molecular weight of not more than 420.
