Abstract

The invention relates to a spherical composite film digital paper for thermal sublimation transfer printing, belonging to the technical field of thermal sublimation transfer printing. The spherical composite film digital paper comprises, from bottom to top, a substrate paper (1), a spherical composite film (2) and a surface channel layer (3), wherein the spherical composite film (2) is an interpenetrating network spherical composite film composed of hydrophilic network resin and a porous inorganic substance, or cyclodextrin, or a composition of the porous inorganic substance and cyclodextrin,and the hydrophilic network resin is interpenetrating network resin formed by separate crosslinking of cationic polyacrylamide with an acrylic resin composition and carboxymethylcellulose sodium; andthe spherical composite film (2) will expand and wrap up a dye and realizes multilevel separation of dye molecules and water molecules, and the network density of the spherical composite film is adjusted to improve water permeability. The spherical composite film (2) is directly connected with the substrate paper (1), so rapid drying of ink can be achieved. The coating of the spherical composite film digital paper in the invention is of a two-layer structure; and the spherical composite film digital paper is simple in production process, capable of drying immediately after printing, fast in ink absorption and good in transfer printing effect, and meets the requirements of rapid printing and efficient production.

Description

technical field [0001] The invention relates to the technical field of thermal sublimation transfer printing, in particular to a spherical composite film 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 pattern and ink. When heated to 180-230°C, the pattern is transferred and printed on different material media, which basically ensures that all dye molecules are transferred to the media material. [0003] Patent application number 201410849229.2 is a self-adhesive fast-drying thermal sublimation transfer digital paper, which discloses a di...
