Easy-to-use ink-jet heat sublimation transfer paper

The invention discloses an easy-to-use ink-jet heat sublimation transfer paper. The paper comprises an ink holding layer, a paper fiber binding layer, a base paper layer and a back coating. The top layer of the transfer paper is the ink holding layer, the bottom layer of the transfer paper is the back coating and the paper fiber binding layer and the base paper layer are arranged between the ink holding layer and the back coating or a mixture layer of the paper fiber binding layer and the base paper layer is arranged between the ink holding layer and the back coating. The base paper layer is coated with the paper fiber binding layer through a coating machine or through a glue applicator in a paper machine in base paper layer preparation. Only one layer of the ink holding layer with very small thickness can prevent a dispersed dye from permeating into paper fibers and has an ink dye holding capacity which is 1.5-2.5 times that of carboxymethylcellulose and is more than 5 time that of polyvinyl alcohol so that a transfer rate is effectively improved. The coating has pore number greater than or equal to 20 per square millimeter so that an ink absorption capability is improved. Through use of the dried filling material in the transfer paper, a drying rate is fast in printing, a transfer paper shrinkage ratio is low, transfer paper water absorption arching-caused friction on a printer is avoided in ink-jet printing and the transfer paper can be used easily.
