Aquosity optical variable ink and preparing method thereof

Abstract

The invention discloses an aquosity optical variable ink comprising conditioner and auxiliary agent, wherein the conditioner comprises: 25-35% of water-borne acrylic membrane forming emulsion, 20-25%of water-borne acrylic non membrane forming emulsion and 30-35% of aquosity resin liquid; the aquosity resin liquid is composed of 15-25% of water, 15-25% of alcohol, 10-15% of ammonia water or ethanolamine and 30-40% of solid macromolecule acrylic resin; the auxiliary agent comprises 0.1-0.5% of aquosity defoamer, 0.2-2% of flatting agent, 8-12% of aquosity wax liquor, 0.5-2% of scratch resistance agent and 1-3% of membrane forming agent; in the mixed liquor of the conditioner and the auxiliary agent, 10-20% of smashed optics discoloration film is added. The ink thoroughly changes the problemof organic matter residue in printing material; in addition, the aquosity optical variable ink has the characteristics of wide application range, lower price, strong adhesive force with printed material base material, week variability characteristics and big chromatism variation.

Description

technical field [0001] The invention relates to raw materials in the printing industry, in particular to a water-based optical color-changing ink and a production method. Background technique [0002] With the development of the market economy, more and more brand-name products have put forward the demand for anti-counterfeiting technology applications. The existing range of printing inks has a narrow application range, high prices, poor adhesion to substrates, and optical changes. Weak characteristics, little change in color difference. In addition, the existing optical color-changing inks contain more or less volatile organic compounds, especially the inks used in screen printing, letterpress printing, gravure printing, and lithographic printing all contain volatile organic compounds. Since volatile organic compounds generally contain many harmful substances to the human body and the environment, these harmful substances may penetrate through the packaging into food, medi...

Problems solved by technology

In the prior art, there are also water-based inks and water-based optical color-changing inks with lower volatile organic compound content, such as Chinese patent 00104371.4; 02158999.2; 95120946.9; 97198466.2; The technical solution disclosed in is only applicable to the special ink for printers, or the special ink for writing refills, or the printing of some simple packaging products.

At present, the special inks for screen printing, letterpress printing, gravure printing, and lithographic printing used in large quantities in the printing industry also contain more volatile organic compounds, and it is not easy to achieve anti-counterfeiting effects.
