Abstract

The invention discloses a gravure alcohol aquosity composite plastic ink, which comprises the following parts: polybasic allyl propionate copolymerized resin, polyketone resin, dye, dispersant, adhesion accelerating and chelant and alcohol. The invention makes ink possess excellent alcohol solubility and solvent releasing property, which improves ink fluidity and adhesion effectively.

Description

technical field [0001] The invention relates to an ink, in particular to a gravure alcohol water-based composite plastic ink and a preparation process thereof. Background technique [0002] In recent years, with the rapid development of the packaging industry, the plastic gravure ink market is also growing. At present, in the printing of plastic films in my country, gravure printing has unique features that cannot be compared with other printings. It is very popular in the industry and is generally optimistic about the development prospects of plastic gravure printing inks. Gravure printing inks are widely used in the plastic packaging industry. , such as plastic packaging for food, medicine, feed, agricultural products, daily necessities, etc., almost includes the packaging of various industries, especially for food packaging. The colorful and novel packaging placed on the food shelves of major shopping malls and supermarkets , A variety of foods are packaged in plastic grav...
