Problems solved by technology

[0005] Although the above-mentioned cast-coated photo paper has good gloss, it is suitable for printing high-gloss photos, but because the coating is cast-coated, the openness of the pores in the coating is reduced, and the glossy layer on the surface forms a denser layer due to the drying of the press cylinder. surface, not suitable for printing with pigment ink machines

Abstract

The high luster painted photographic paper for ink jet printing is formed through painting two layers of coating fluid containing ink absorbing pigment and passing through metal mirror casting jar. The upper layer of the coating fluid consists of inorganic pigment 90-100weight portions, PVA 3-5weight portions, polymer emulsion 5-30weight portions, assistant 3.5-6weight portions, and deionized water 580-780 weight portions. The high luster painted photographic paper is applied in printing photos with water soluble dye ink and water soluble pigment ink, and has reliable printing performance and capacity of obtaining printed photos with bright colors.

Description

technical field [0001] The invention relates to an ink-jet printing consumable, in particular to a high-gloss cast-coated photographic paper for ink-jet printing. Background technique [0002] Inkjet printing is widely used in various fields because of its fast recording speed, easy colorization, convenient application and no pollution. In the field of imaging, inkjet printing technology has developed rapidly and has become a substitute or complementary material for traditional silver salt photos. Inkjet printing photo paper can be divided into three categories according to the coating process and coating materials: swelling type, microporous type and cast coating type. Swelling type photo paper is coated with water-swellable polymer as the main film-forming material on RC paper (coated with waterproof PE coating on both sides of the base paper) to form a high-gloss swelling type coating. The photo paper is mainly suitable for water-based dyes. Ink printing; microporous in...
