摘要： A transfer recording medium capable of obtaining a satisfactory transfer image is provided without fusing a base film due to heat even if the medium is used for a printer using a large-output laser beam. The medium is made by forming an adiabatic layer or a heat absorbing layer between the base film and a light-heat conversion layer or an ink layer containing a light-heat conversion agent and sublimating dye formed on one side of the base film or forming the heat absorbing layer on the other side of the base film.

摘要： A thermal transfer recording medium such as a color thermal transfer paper or ribbon which is used in combination with a thermal head or pen to print an image on an image forming body or sheet. The thermal transfer recording medium comprises a polyester supporting film, a first thermal transfer layer formed on the supporting film, which consists mainly of a saturated polyester copolymer having a molecular weight of 8,000 to 30,000 and containing a sublimation or hot-melt transfer dye. A second thermal transfer layer containing a dye as that of the first transfer layer may be formed on the first transfer layer. The thermal transfer image forming body comprises a supporting body, a dyeing image forming layer formed on the supporting body and made mainly of a thermoplastic resin having four or more OH group per molecule, a tensile break strength of 300 kg/cm.sup.2 or more and tensile break elongation of 20% or more, and a surface layer made of a silicone resin.

摘要： A thermal transfer recording medium comprises a substrate and, laminated thereto, an ink layer containing a sublimation dye and a binder resin. The binder resin comprises (a) from 60 to 90% by weight of polyvinyl butyral with a degree of polymerization of from 1,500 to 2,500 and a glass transition point of not lower than 70.degree. C., and (b) from 10 to 40% by weight of ethyl cellulose with a glass transition point of not lower than 130.degree. C.
