Abstract

The invention relates to a high glaze cast-coated photographic paper for ink-jet printing. A layer of coating fluid containing a blotting pigment is coated on a support body, and the support body is dried by a heated metal mirror casting cylinder to obtain the high glaze cast-coated blotting pigment, wherein the coating fluid comprises the following components in portion by weight: 90 to 100 portions of inorganic pigment, 3 to 5 portions of polyvinyl alcohol, 5 to 30 portions of polymer emulsion, and 2 to 5 portions of other auxiliary agents. By using the cast-coated photographic paper manufactured by the invention, a printed photo has bright colors, and the printing performance is reliable; and the cast-coated photographic paper not only is adaptable to water-based dye ink printing, but also is adaptable to water-based pigment ink printing.

Description

technical field [0001] The invention relates to an ink-jet printing consumable, in particular to an ink-jet printing cast-coated photographic paper. 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 print. Microporous inkjet printing ph...
