Problems solved by technology

However, the traditional water-based varnish itself is colorless. If you want to keep the color on the coating, you need to do printing coating and other processing to achieve it. The complexity affects its scope of use, greatly restricts its promotion and application scope, and easily causes a lot of cost waste

Abstract

The invention relates to a water-based colored glazing agent free from printing. The proportioning is realized through 10-20% of organic pigment and 80-90% of water-based glazing agent by mass percentage, wherein an organic toner comprises 40-45% of organic toner and 55-60% of acrylic emulsion by mass percentage. The water-based colored glazing agent can achieve a multi-color effect free from printing, and is high in solid content, non-toxic and odorless, so that the harm to a human body and the pollution to the environment are eliminated, and the water-based colored glazing agent has the advantages of high drying speed, good film transparency, stable performance, wide equipment adaptability, good wear resistance and flatness of the glazed surface, wide post-press finishing eligibility and good heat sealing performance and is safe and reliable to use and convenient to store and transport. The water-based colored glazing agent provided by the invention is stable in comprehensive performance and convenient to produce, generalize and use, and has a broad market prospect.

Description

technical field [0001] The invention relates to water-based varnish, in particular to a printing-free water-based colored varnish. Background technique [0002] Water-based varnish is a new type of printing varnish material that developed countries have been vying to research and develop in recent years, and it is increasingly valued by people in the printing industry. It is a method of printing varnish once or twice on the surface of the replica that has completed the graphic printing process with a solid printing plate or a graphic printing plate, so that the surface of the printed matter can obtain a bright film layer. [0003] Water-based varnish (called WATER BASE DVARNISH in English, or DISPEERSE DVARNISH) is mainly composed of water-soluble resin and water-dispersible resin. Water-based varnish is non-toxic and tasteless, eliminating the harm to the human body and the Environmental pollution, with fast drying speed, good film transparency, stable performance, wide eq...
