THERMAL TRANSFER FILM RIBBON

摘要

PURPOSE:To obtain a highly detailed printing image, by constituting the stickiness preventing layer of a thermal transfer film ribbon of a specific silicon modified vinyl copolymer. CONSTITUTION:A thermal transfer ink layer is provided to the surface of a plastic film and a stickiness preventing layer is provided to the rear thereof. This stickiness preventing layer is composed of a silicon modified vinyl copolymer obtained by the radical polymerization of polysiloxane having an ethylenic unsaturated group and a radical copolymeric monomer and the heating temp. thereof at the time of a thermal weight change of 95 is 400 deg.C or more. A heating head is slid with this stickiness preventing layer and selectively heats the thermal transfer ink layer to form a printing image. At this time, a thermal transfer film ribbon is prevented from the generation of a hole large enough to obstruct the formation of a highly detailed printing image.
