Problems solved by technology

The invention patent has poor adhesion to the support and needs to be coated with a primer first
[0007] The inkjet media disclosed in Chinese patents CN 103897540 A and CN102658744A do not mention the drying speed after printing. Although CN102658744A mentions fast drying, its drying time is as long as 5 minutes
This is because the current commercially available weak solvent inkjet media has the problem of slow drying after printing, so most of the commercially available inkjet equipment is designed with a heating plate to assist heating to ensure that the printed image is completely dry during winding and will not cause image adhesion. question

Abstract

The present invention relates to a weak solvent type inkjet media and a preparation method thereof. The inkjet media comprises a support body and a weak solvent ink receiving layer on one or both sides of the support body, wherein a coating liquid is coated and dried to form the weak solvent ink receiving layer, and comprises, by weight, 10-30 parts of inorganic particles, 40-90 parts of water, 10-50 parts of a polymer emulsion, and 5-10 parts of a non-aqueous solvent. According to the present invention, the prepared weak solvent type inkjet media has characteristics of good coating fastness, high coating surface gloss, smooth and anti-sticking coating surface, rapid drying after printing, good ink absorption property, high color density, and good weather resistance.

Description

technical field [0001] The present invention relates to an inkjet medium, in particular to a weak solvent type inkjet medium. Background technique [0002] The ink jet recording method has been rapidly popularized due to its advantages of no pollution, low noise, and the possibility of printing without printing. It has been widely used in the fields of imaging and advertising. [0003] The inkjet recording method is to perfectly print the digital image on the inkjet medium through the inkjet printer. The quality of the image output depends on the inkjet accuracy of the print head, the performance of the inkjet ink and the receiving medium, and the matching of the two. For commercially available inkjet printers, the inkjet accuracy and inkjet ink performance of the print head have been determined, so the performance of the receiving medium and its matching with the inkjet ink are the keys to determining the image quality. According to the type of solvent, inkjet ink can be d...
