Problems solved by technology

[0010] The ink-absorbing ability of the ink-absorbing layer of the structure disclosed above is insufficient, and a high coating amount is required to obtain sufficient ink-absorbing ability
In the coating production, due to the long drying time and slow setting speed during the drying process of the coating film with high coating amount, the coating film is easily disturbed by the drying environment and affects the quality
For example, dust pollution in a dry environment can cause shrinkage cavities

Abstract

The invention supplies a ink jetting coating fluid that has freeze temperature. The feature includes: 10-25% alumina and hydrate, 1-2.5% water-soluble polymer, 0.05-0.5% curing agent, 2-25% water-soluble organic solvent, and the other is wather. The invention would avoid shrinkage cavity disadvantage when coating much.

Description

technical field [0001] The invention relates to an ink-jet coating liquid, in particular to an ink-jet coating liquid with freezing point temperature. Background technique [0002] Inkjet printing is a low-cost, colorful, and on-demand color printing method. Water-soluble inkjet inks generally consist of water, water-soluble dyes or pigmented dyes, one or more water-compatible co-solvents and one or more surfactants. The substrate (inkjet ink medium) can be flat paper, sized paper, plastic film, cloth, or other medium capable of absorbing ink to form a good image. To form high-resolution images, the substrate typically absorbs the sized layer with a specially formulated inkjet ink. The sizing layer can be divided into two categories, swelling type and interstitial type. [0003] Swelling sizing layers consist essentially of film-forming polymers (polymeric sizing layers), at least one of which is hydrophilic. The hydrophilic polymer is water soluble or water swellable. ...
