Printing ink having the function of changing color and shining and suitable for film products

Abstract

The present invention relates to a printing ink having the function of changing color and shining and suitable for lamination, the raw material formula of which comprises the following constituents by weight: 5% to 30% of acrylic resin, 40% to 85% of butanone, 3% to 5% of glycol ether, 0.6% to 1% of acetate, 2% to 25% of nano powder and 0.9% to 1.8% of conductive salt. The nano powder comprises one or more of the following powder: temperature-sensitive color-changeable nano powder, light-sensitive color-changeable, ultraluminescence nano powder and infrared-luminescent nano powder. By adopting the above technical scheme including taking acrylic resin as binder and using mixed solvents with specific formula accordingly, the adhesion between the ink and glass with smooth surface, polypropylene films and PET films is enhanced greatly. Particularly, the color-changeable or luminous nano powder is used in the ink, but the adhesion between the ink and the materials with smooth surface is strong. Therefore the ink can be applied to film products.

Description

technical field [0001] The invention relates to an ink, in particular to an ink which has the function of changing color or emitting light and is suitable for pasting films. Background technique [0002] At present, there are a large number of fake and counterfeit products on the market, often under the guise of a certain famous brand. The outer packaging can almost be fake and the real ones, and consumers cannot identify them. Consumers are damaged and the goodwill of regular brands is also affected. Therefore, merchants of regular brands generally affix unique anti-counterfeiting labels on the products they sell to prevent this kind of situation. [0003] However, counterfeiting of various film products currently on the market is still very serious. Film products, such as the most widely sold heat-insulating sunscreen film (also known as heat-insulating film, heat-insulating paper, space film, etc., among which, "heat-insulating" refers to the effective blocking of infrar...

Problems solved by technology

), the anti-scratch, anti-ultraviolet, infrared and other functions claimed by this type of product, ordinary consumers do not have special equipment to identify, and the existing film products of this type cannot use anti-counterfeiting labels or directly spray anti-counterfeiting spray The reason is that in the prior art, alkyd resins, vinyl resins, phenolic resins, etc. are often used as the main raw materials to produce various types of inkjet inks, and such inkjet inks are difficult to adhere to glass with smooth surfaces, Polypropylene film, PET film, photocurable resin layer and other materials, these inks are easy to be wiped off after spraying; especially, it is generally necessary to add some Luminous or discolored powders, the addition of these powders further seriously affects the adhesion of inks to smooth surfaces
