Problems solved by technology

The ink-absorbing ability of the ink-absorbing layer of this structure is not enough, and a high coating amount is required to obtain sufficient ink-absorbing ability
[0011] 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 present invention provides an inkjet coating solution having a freezing point temperature and a manufacturing method of a porous type inkjet recording medium. An ink-jet coating solution with a freezing point temperature, characterized in that it comprises the following proportioning components: 10-25% by weight of aluminum oxide and hydrate; 1-2.5% by weight of a water-soluble polymer; 0.05-0.5% by weight % by weight of curing agent; 2-25% by weight of water-soluble organic solvent; the balance is water. A method for manufacturing a porous inkjet recording medium. The present invention manufactures the ink-jet recording medium whose glossiness (60 degree angle of incidence) is higher than 40 according to the following method steps: by means of a constant temperature feeding system and a coating system, the coating liquid with freezing point temperature is placed above Coating on the substrate at the coating temperature of the freezing point to form a coating film; the coating film is quickly pre-dried by a freeze-drying section and then dried to form a film.

Description

technical field [0001] The invention relates to a method for preparing an inkjet recording medium, in particular to a method for manufacturing an inkjet recording medium with a glossiness (incident angle of 60 degrees) higher than 40. Background technique [0002] Inkjet printing is a low-cost, colorful, and on-demand color printing method. With the advent of the computer multimedia era, high-resolution digital cameras, small inkjet printers, and high-quality photo printers have entered modern offices and homes on a large scale. This has led to the rapid growth and development of the printing consumables market, which is indispensable for achieving excellent print output. Especially when the quality of inkjet printing is getting higher and higher, and the printed images are comparable to traditional photos, photo printing has become a real user demand, and this demand also promotes the further development and improvement of inkjet media technology. [0003] The projector p...
