A thermal transfer recording medium that is capable of dealing with the requirement for an increase in thermal transfer printing speed, and high density and high quality of a thermally transferred image, capable of preventing the occurrence of abnormal transfer at high temperature and high humidity, and capable of improving transfer sensitivity in printing. A thermal transfer recording medium includes a heat-resistant lubricating layer on one surface of a base material, and an undercoat layer and a dye layer in that order on the other surface of the base material. The undercoat layer includes a copolymer of a polyester having a sulfonic acid group and an acrylic polymer having at least one of a glycidyl group and a carboxyl group, polyvinylpyrrolidone, and an oxazoline group-containing polymer. A binder resin of the dye layer is an acid-modified polyvinyl acetoacetal resin.
一种热转印记录介质,能够满足提高热转印打印速度、高密度和高质量热转印图像的要求,能够防止在高温和高湿条件下出现异常转印,能够提高打印中的转印灵敏度。一种热转印记录介质包括位于基底材料一个表面上的耐热润滑层,以及位于基底材料另一个表面上的依次排列的底涂层和染料层。底涂层包括具有磺酸基的聚酯和具有缩水甘油基和羧基中至少一个的丙烯酸聚合物的共聚物、聚乙烯吡咯烷酮和含噁唑啉基的聚合物。染料层的粘合剂树脂是一种酸改性聚乙烯醇缩乙醛树脂。
