Abstract

Disclosed is pigment ink for ink-jet printing, which is composed by mixing color paste, resin, pH regulating agents and de-ionized water and is characterized in that the weight percent of the color paste is 10-50%, the weight percent of the resin is 0.1-3%, the weight percent of the pH regulating agents is 0.1-2%, and the rest is the de-ionized water. The advantages and technical effects of the invention are in that satisfied scuff resistance can be achieved by changing the added resin, fingers can smear on the surface of printed materials without leaving any marks after printing is finished, strong luster sensation is achieved together with the scuff resistance, and stability and drying time of the ink can not be influenced after the resin is added.

Description

(1) Technical field: [0001] The invention relates to a printing pigment ink, in particular to an inkjet printing pigment ink. (two) background technology: [0002] Ink for inkjet printing can be divided into pigment ink and dye ink. The dye in the dye-based ink exists in a molecular state, so the printed image obtained is clear and the color gradation transition is uniform, but it is easy to fade and has poor water resistance. [0003] The pigment in the pigment ink is granular, and the pigment can be dispersed in water by grafting the pigment or treating it with a dispersant. The printed matter thus obtained has the advantages of light resistance and water resistance, but when the pigment ink is printed on photo paper, most of the pigment particles stay on the surface of the photo paper, so it is difficult to obtain satisfactory rub resistance, and due to the The pigment exists in the state of particles, and the light forms diffuse reflection on the surface of the printed...
