A receiver paper used in combination with a thermally transferrable sheet, such as an ink ribbon, in which a laminated layer of the thermally transferrable sheet can be positively transferred, with the receiver paper exhibiting superior running performance and resistance to blocking to enable a picture of high quality and high resolution to be produced. To this end, there is provided a receiver paper made up of substrate and a dye reception layer formed on the substrate. The dye reception layer contains a copolymer of a compound having a pre-set chemical formula and another monomer.

Thermally transferred sheet

A thermal transfer sheet having a base sheet; a thermal transfer dye layer formed on the front side of the base sheet; and a heat resisting and lubricating layer formed on the reverse side of the base sheet. Even if the thermal transfer dye layer contains an indoaniline dye, deterioration in the indoaniline dye can be prevented, the preservability of the thermal transfer can be maintained, fusion of the thermal transfer sheet to a thermal head can be prevented and smooth movement of the thermal transfer sheet is enabled. Thus, sticking which occurs during a printing operation can be prevented. The thermal transfer sheet according to the present invention has a base sheet; a thermal transfer dye layer formed on the right side of the base sheet; and a heat resisting and lubricating layer formed on the reverse side of the base sheet, wherein the thermal transfer dye layer contains an indoaniline dye, and the heat resisting and lubricating layer contains polyoxyethylene sorbitol fatty acid ester and phosphoric ester at a weight ratio of 10:1 to 1:2.

Thermal transfer sheet

The present invention provides a thermal printing sheet which enables to realize a stable low friction coefficient within a heating range by a thermal head and which has a superior preservation stability without giving an adverse affect to dye layers. The thermal printing sheet according to the present invention includes a substrate sheet 1, on one side of which are formed thermal dye layers 2 and on the other side of which is formed a heat resistant slide layer 3. The heat resistant slide layer 3 contains polyoxyalkylene sorbite fatty acid ester which exhibits a superior lubrication characteristic, enabling to obtain a low friction coefficient even under a high temperature. Moreover, the polyoxyalkylene sorbite fatty acid ester is neutral and does no adversely affect the dye layers. The heat resistant slide layer 3, in addition to the polyoxyalkylene sorbite fatty acid ester, may contain polyglycerin fatty acid ester and metallic soap.
