Problems solved by technology

[0005] However, the inventors used the heat-sensitive transfer recording media with the configurations described in Patent Documents 1 and 2 to print on a high-speed printer of the sublimation transfer method. Abnormal transfer occurs during thermal transfer, and it is impossible to obtain a sufficiently satisfactory quality printed matter using the existing thermal transfer recording medium

Embodiment 1

[0140] On the side of the substrate with a heat-resistant slippery layer that is not coated with a heat-resistant slippery layer, the coating amount after drying is 0.20 g / m by gravure coating 2 An undercoat layer coating liquid-1 having the following composition was applied in the manner described above, and dried at 100° C. for 2 minutes to form an undercoat layer. Continue to use the gravure coating method on the undercoat layer so that the coating amount after drying becomes 0.70g / m 2 A dye layer coating solution-1 having the following composition was applied in the manner described above, and dried at 90° C. for 1 minute to form a dye layer. Thus, the thermal transfer recording medium of Example 1 was obtained.

Abstract

Provided is a thermal transfer recording medium which meets requirements for higher speed of thermal transfer printing and requirements for high density and high quality of thermally transferred images, while being prevented from the occurrence of abnormal transfer under high temperature high humidity conditions, and which has improved transfer sensitivity for printing. This thermal transfer recording medium (1) comprises a heat-resistant lubricating layer (40) on one surface of a base (10), and sequentially comprises an undercoat layer (20) and a dye layer (30) in this order on the other surface of the base (10). The undercoat layer (20) is composed of a copolymer of a polyester having a sulfonic acid group and an acrylic compound having a glycidyl group and / or a carboxyl group, a polyvinyl pyrrolidone and an oxazoline group-containing polymer. A binder resin constituting the dye layer is an acid-modified polyvinyl acetoacetal resin.

Description

technical field [0001] The present invention relates to thermosensitive transfer recording media. Background technique [0002] In general, a thermal transfer recording medium is called a thermal ink ribbon, and is used, for example, as an ink ribbon of a thermal transfer type printer. [0003] Examples of conventional thermal transfer recording media include those described in Patent Documents 1 and 2. In Patent Document 1 or Patent Document 2, a thermosensitive transfer layer is described in which one surface of a substrate is provided with a thermal transfer layer and the other surface of the substrate is provided with a heat-resistant slippery layer (back coat layer). recording medium. Here, the thermal transfer layer has a layer (dye layer) containing ink, and the ink is sublimated (sublimation transfer method) or melted (melt transfer method) by the heat generated at the thermal head of the printer, thereby Transfer to the side of the object to be transferred.
