摘要:热升华转印纸承载热升华转印油墨印刷的文字或图案,并在受热、加压的条件下将文字或图案转移到承载物上。转印纸均匀、高品质的涂层表面是获得良好转印效果的基础。本文研究了影响热升华转印纸涂层及打印油墨干燥速率和转印效果的因素。结果表明,挥发性两性溶剂的加入可提高涂布纸涂层的干燥速率,自制高阳离子度聚合物和大孔容SiO₂气凝胶的加入能大大缩短打印后热升华油墨的干燥时间,并获得较好的转印效果。

Abstract:The sublimation transfer printing paper has been used as the intermediate on which the texts or pictures were printed using sublimation-transfer-ink. Under heating and pressurizing condition, the sublimation transfer ink was forced to transfer from paper surface to specific objects. The quality of sublimation transfer paper was determined by the uniform and high-quality coating layer. In this paper, the influences of coating process on drying rate of the coated paper and sublimation result were discussed. The results showed that, the coating materials containing amphoteric solvent were beneficial for drying rate of the coated layer, the drying rate of the sublimation ink and the sublimation transfer effect were improved by the addition of polymer with high cationic degree and the SiO2 filler with high pore volume．
