Instant dry sublimation transfer digital paper

Abstract

The invention relates to the technical field of heat sublimation transfer, and discloses instant dry type heat sublimation transfer digital paper. The instant dry type heat sublimation transfer digital paper sequentially comprises base material paper, a water absorbing and permeating layer, a porous layer and a surface channel layer from bottom to top. The porous layer is interpenetrating polymer network resin formed by cross linking of cellulose or sodium carboxymethylcellulose or starch and cation modified polyacrylamide or formed through cross linking of polyacrylamide or cellulose or sodium carboxymethylcellulose and cation modified starch. On one hand, the interpenetrating polymer network resin can expand to pocket dyestuff, and rapid ink sucking is conducted; and on the other hand, resin components are adjusted, the network density is controlled, so that the water permeability is improved, and water molecules rapidly enter the water absorbing and permeating layer. Holes are formed in the hydrophilia end of the water absorbing and permeating layer, and water in ink is adsorbed into the holes and rapidly transmitted to the cellulose paper base material. The instant dry type heat sublimation transfer digital paper has the beneficial effects that dryness can be achieved immediately during printing, ink absorbing is rapid, and the transfer effect is good; and requirements of existing rapid printing and efficient manufacturing are met.

Description

technical field

[0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to an instant dry thermal sublimation transfer digital paper. Background technique

[0002] Thermal transfer printing technology refers to printing text, graphics and other content on plain paper or high-precision printing paper with thermal printing ink, and then heating it to 180-230°C within a few minutes by the corresponding thermal transfer equipment A special process in which the colors of images are transferred to different materials realistically. Transfer printing digital paper is the carrier of patterns and inks. It is transferred and printed on different material media by heating to 180-230°C, which basically ensures that all dye molecules are transferred to the media material.

[0003] Patent application No. 99810480.9 discloses a transfer paper for inkjet printing, which has a release layer or a barrier layer on the side to be printed, and...
