Solvent type intaglio mirror ink for transparent plastic thin film

Abstract

The invention discloses solvent type intaglio mirror ink for a transparent plastic thin film, aiming at the problems in the prior art that processes including electroplating, transfer printing or silver plating and the like are commonly adopted if intaglio ink for a plastic thin film needs to be processed into a mirror image effect as a mirror, the two processes have the disadvantages of low production efficiency, high cost and the like and an existing silver ink formula also has the conditions of poor mirror effect, unsmooth construction, relatively high price and the like. The solvent type intaglio mirror ink for the transparent plastic thin film, disclosed by the invention, is prepared from the following raw materials in percentage by weight: 20 percent to 50 percent of a vacuum aluminum plating suspension solution, 40 percent to 70 percent of resin and 10 percent to 30 percent of a solvent. The prior art is optimized and a traditional process is replaced with an ink-printing manner, so that the solvent type intaglio mirror ink is more suitable for actual online production, the cost is reduced and the mirror effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a solvent-based gravure mirror ink for transparent plastic films. Background technique [0002] In the prior art, the gravure inks for plastic films (PET / BOPP / PE / PVC, etc.) are mostly colored inks, and the metal inks used are generally gold-silver inks or copper-gold inks prepared by ordinary aluminum-silver paste. The mirror surface generally has a mirror image effect, and generally adopts electroplating, transfer printing or hot silver processes, but these two processes have disadvantages such as low production efficiency and high cost, and the existing silver ink formulations also have insufficient mirror effect and poor construction. , the price is high and so on. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a solvent-based gravure mirror ink for transparent plastic films, which is opt...
