Temperature-sensitive sticky instantly-dry thermal sublimation transfer printing digital paper

Abstract

The invention relates to the technical field of thermal sublimation transfer printing, and discloses temperature-sensitive sticky instantly-dry thermal sublimation transfer printing digital paper. The paper sequentially comprises substrate paper, a water absorption and water permeable layer, a porous layer, a channel layer and a surface bonding layer from bottom to top; the surface bonding layer is a composite of a combination of any two or more than two of a polyvinyl alcohol-vinyl acetate copolymer, an ethylene-vinyl acetate-vinyl alcohol copolymer, sodium carboxymethylcellulose and polyvinyl alcohol and polyhydric alcohols; the porous layer is interpenetrating polymer network resin, the interpenetrating polymer network resin can expand to contain dye and quickly adsorb ink, and the purpose that water molecules quickly enter the water absorption and water permeable layer is achieved by regulating composition of the resin and controlling the network density. According to the temperature-sensitive sticky instantly-dry thermal sublimation transfer printing digital paper, the surface bonding layer has no stickiness at room temperature, and therefore the digital paper can be conveniently rolled up; when the digital paper is heated to the specific temperature, the surface of the transfer printing paper has the very good stickiness to stick an elastic bearing object, and the advantages of being clear in transfer-printed image detail and bright and saturated in color are achieved; after transfer printing is completed and the temperature is lowered, the digital paper is automatically separated from the bearing object, and the temperature-sensitive advantage is achieved.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to a temperature-sensitive viscous, dry-type 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. The printing method is divided into two parts: transfer film printing and transfer printing processing. The transfer film printing adopts dot printing, and the pattern is pre-printed on the surface of the film. The printed pattern is rich in layers, bright in color, ever-changing, with small color difference and good reproducibility. And it is suitable for mass production; t...
