Embodiment 1

[0032]

[0033] The preparation method is:

[0034] First add deionized water and alcohol into the reaction vessel, start the disperser and mix thoroughly at 500-600r / min, then slowly add other materials while stirring according to the discharge sequence, after dispersing for 50 minutes, filter and pack with 200-mesh filter cloth for use. Because no colorant is added in the present embodiment, what obtains is water-based laser anti-counterfeiting ink varnish.

Embodiment 2

[0036]

[0037] The preparation method is:

[0038] First add deionized water and alcohol into the reaction vessel, start the disperser and mix thoroughly at 500-600r / min, then add defoamer, wetting and dispersing agent, and colorant. After dispersing at 600-1000r / min for 40 minutes, slowly add other materials while stirring according to the discharge order, and after dispersing for 50 minutes, filter and pack with 200-mesh filter cloth for use. The water-based laser anti-counterfeiting transparent ink is obtained.

Embodiment 3

[0040]

[0041] The preparation method is:

[0042] First add deionized water and alcohol into the reaction vessel, start the disperser and mix thoroughly at 500-600r / min, then add defoamer, wetting and dispersing agent, and pigment. After dispersing at 600-1000r / min for 40min, put the dispersed material into a horizontal sand mill and grind it two times and three times until the fineness is less than 10 microns and discharge the material. , slowly add other materials while stirring according to the discharge sequence, after dispersing for 50 minutes, filter and pack with 200-mesh filter cloth for use. The water-based laser anti-counterfeiting opaque ink is obtained.

Abstract

The invention relates to a water-based laser anti-counterfeiting ink, which is composed by weight percentage: 15-30% deionized water, 15-30% alcohol, 0.01-2% defoaming agent, 0.1-4% wetting and dispersing agent, 20-40% water-based polyurethane, 5-20% water-based acrylic resin or 5-25% colorant. The ink passed through the technical solution has good adhesion fastness after printing, water resistance, oil resistance, etc., protects the laser anti-counterfeiting pattern, and can print different effects on the same laser pattern.

Description

technical field [0001] The invention belongs to the field of coatings, and specifically refers to a water-based anodized aluminum packaging composite film color layer ink used in the packaging and printing industry. Background technique [0002] Laser holographic anti-counterfeiting (laser anti-counterfeiting) technology is an internationally recognized promising anti-counterfeiting technology and a new type of anti-counterfeiting packaging and printing material. According to the anti-counterfeiting requirements of the paper packaging industry, it organically combines a number of technologies in different disciplines such as laser holographic stamping, computer lithography, special plate making, precision electroforming, coarse and fine chemical engineering, and high-precision peeling to make a transferable holographic plastic film. Then transfer it to paper to make laser holographic transfer paper. In China, molding laser technology was first applied in the field of anti-c...
