Abstract
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.
Claims3
A thermal transfer recording film having a film base and a thermal transfer recording layer on one surface of the film base, which is characterized in that a back-coat layer containing silicone as chemically bonded to 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, in which the silicone chemically bonded to a binder resin is a graft copolymer of silicone with a binder resin or a reaction product of a terminal amino-modified reactive silicone oil with a binder resin.
