Problems solved by technology

In this way, the thermal transfer sheet has another problem: when heat is supplied from the back of the substrate to the protective layer with a thermal head, heat energy higher than the supplied heat energy is unevenly supplied to the protective layer in stripes, causing The transferred protective layer exhibits a streaky pattern due to uneven gloss, resulting in an uneven image

Embodiment 1

[0296] In Example 1, a 6 µm-thick film (trade name: 602 6.0E, manufactured by Diafoil Corp.) treated to improve adhesion was used as the base film. A back layer coating liquid (heat resistant layer coating liquid) having the composition shown in Table 1 was coated on one surface of the base film by printing, followed by drying to form a back layer. A primer layer coating liquid having a composition shown in Table 2 was applied on the other side by printing, followed by drying to form a primer layer. The primer layer contains a fluorosurfactant (carboxylate) of formula (1).

Embodiment 2

[0313] In embodiment 2, thermal transfer recording medium is prepared like embodiment 1, but with the fluorosurfactant (trade name: Ftergent150, Neos Co. , Ltd.) in place of the fluorine-containing surfactant used in the primer layer, and polyvinyl acetal (trade name: S-Lec BX-1, Tg: 90°C, produced by Sekisui Chemical Co., Ltd.) Polyvinyl acetal used in the release agent layer.

Embodiment 3

[0315]In Example 3, a thermal transfer recording medium was prepared as in Example 1, but the fluorosurfactant (trade name: FC4430 produced by Sumitomo 3M Limited) represented by the formula (1) was used instead of the one used in the primer layer. Fluorine-containing surfactant and polyvinyl acetal (trade name: S-Lec BX-5, Tg: 86°C, manufactured by Sekisui Chemical Co., Ltd.) in place of the polyvinyl acetal used in the release agent layer .

Abstract

The application discloses a thermal transfer recording medium having at least one transferable protective layer arranged on a base with a non-transferable release layer provided therebetween, in which the protective layer is detached from the release layer at the interface between the at least one protective layer and the release layer during thermal transfer printing and then thermally transferred onto an image, includes a primer layer containing at least one fluorocarbon-based surfactant, the primer layer, the release layer, and the protective layer being stacked, in that order, on one surface of the base, in which the release layer has a glass transition temperature of 60 DEG C to 110 DEG C.

Description

[0001] Cross References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP 2008-007203 filed in the Japan Patent Office on Jan. 16, 2008, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to a thermal transfer recording medium used in thermal transfer, and more particularly to a thermal transfer recording medium that provides good image surface gloss and good recording characteristics when a protective layer for protecting an image is transferred. Background technique [0004] Hitherto, a color or monochrome image has been formed by using the following technique: an ink sheet containing a thermally diffusible pigment faces the pigment-receiving layer of an image-receiving sheet such as photographic paper, and heats the thermally diffusible pigment with a thermal print head so that the thermally diffusible pigment can The thermal diffusio...
