Abstract

The invention relates to an ink-jet printing material and a method for preparing the ink-jet printing material. The ink-jet printing material comprises a supporting body and an ink absorption coating located on at least one surface of the supporting body. A material for forming the ink absorption coating comprises a core-shell polymer, and the core-shell polymer is obtained by polymerizing a core polymer and a shell polymer. The glass transition temperature of the shell polymer is 70-150 DEG C. Therefore, when the ink-jet printing material passes through a heating unit of an ink-jet printer system, the shell polymer in the core-shell polymer can be subjected to glass transition, the waterproofness of the ink absorption coating is improved, and the traditional film covering or spraying process can be omitted.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an inkjet printing material and a method for preparing the inkjet printing material. Background technique [0002] In recent years, with the increasingly serious environmental problems, people have paid more and more attention to the environment to reduce the discharge of pollutants, which has limited the development of the traditional silver salt imaging industry to some extent. Inkjet printing technology has the advantages of less pollutant emissions and environmental friendliness, and the image quality printed by inkjet printing technology is gradually approaching the level of traditional silver salt photos. These advantages of inkjet printing technology make inkjet printing image output mode It has gradually become the new favorite in the field of imaging, and the market is growing rapidly. [0003] However, when an inkjet printer is used for image output printi...
