| 摘要:本研究主要探讨了微孔型涂层和膨胀型涂层对热升华转印纸的打印和转印性能的影响，优选了2种类型的涂层配方以获得最好的涂布热升华转印纸打印和转印性能。微孔型涂层以二氧化硅为颜料，比例为88份，胶黏剂选择聚乙烯醇。膨胀型涂层以二氧化硅为颜料，比例30份，胶黏剂采用羧甲基纤维素，比例为70份。2种涂层配方相比，微孔型涂层的热升华转印纸透气度高、平整性好、线条清晰度好、干燥速度快（45 s），适合硬质基材的转印；膨胀型涂层的热升华转印纸转印后总油墨色密度高10%，油墨消耗量少、成本低，适合织物的数码印刷。 |
| Abstract:The effects of microporous coatings and swellable coatings on the printing and heat transferring properties of sublimation paper were explored， and the two types of coating formulations were optimized to obtain the best printing and heat transfering performance. Optimum formula of microporous coating was SiO2 with 88 part as pigment and polyvinyl alcohol（PVA）as adhesive. Optimum formula of swellable coating was SiO2 with 30 part as pigment， and CMC with 70 part as adhesive. Compared with the optimal formula of the two types of coating， microporous coating sublimation paper with better air permeability， flatness， and line sharpness， faster drying speed （45 s）， was suitable for hard substrate printing， swellable coating sublimation paper with 10% higher optical density， less ink consumption and low cost， was suitable for digital printing of fabric. |
