A thermal transfer recording film is provided which has a thermal transfer recording layer on one surface of a film base, the unique feature residing in that a back-coat layer containing silicone as fixed on a binder resin and a fluorine-containing surfactant is provided on the surface of the film which comes into sliding contact with a thermal head. This product is free of sticking, excels in slidability on a thermal head, and causes little silicone transfer from the back-coat.

Thermal transfer recording film

A thermal-transfer recording sheet of an aromatic polyester film, wherein at least one surface of said sheet has, as a thermal-transfer ink receiving layer, a coating of a composition comprising (1) a copolyester, (2) a polyolefin fine particle filler and (3) an antistatic compound selected from the group consisting of organic titanate and organic zirconate. The above thermal-transfer recording sheet exhibits excellent adhesion to heat-melting inks and excellent capability of receiving heat-melting ink layers and has good antistatic properties.

Thermal-transfer recording sheet

A thermal transfer record sheet comprising a substrate sheet and a dye receptive layer and a non-tacky layer in this order on at least one surface of the substrate sheet; the dye receptive layer being composed of a crosslinking reaction product of a composition comprising (A-1) a saturated polyester containing units derived from 2,2-bis(4-hydroxyphenyl)propane in the main chain of the polyester and having a glass transition temperature of at least 60.degree. C. and (A-2) a polyisocyanate compound, and the non-tacky layer (B-1) comprising a water-insoluble or sparingly water-soluble fluorine-containing surface-active agent and (B-2) having a thickness of 50 to 200 angstrom.
