PURPOSE:To enhance dyeing properties, image quality preservability, releasability and slip properties and to achieve mass production inexpensively and safely by adding alkyl fluoride to the layer coming into contact with a color sheet at the time of the printing of image receiving paper. CONSTITUTION:Alkyl fluoride is added to the layer coming into contact with a color sheet at the time of the printing of sublimation type heat-sensitive transfer image receiving paper wherein a dyeing layer to be dyed with a sublimable dye is provided to the surface of a base material, that is, an image receiving layer and/or the release layer provided on the image receiving layer. The addition amount of alkyl fluoride is 0.005-2.0%, pref., 0.03-0.1% by wt. of the total amount of a dyeing solution when alkyl fluoride is added to the dyeing solution for forming the dyeing layer. When the addition amount is less than this range, effect is not expected and, when the addition amount is more than this range, a sticky feeling is generated and slip properties becomes inferior and the preservability of image quality also becomes bad. When an aqueous resin having good dyeing properties is used in the dyeing layer, it is extremely effective to use an associative tackifier because viscosity can be appropriately selected and not only dyeing concn. but also releasing action are enhanced and the pot life of the dyeing solution becomes long. |
