Embodiment 1

[0046] This example is used to illustrate the metal ink composition provided by the present invention and its preparation.

[0047]

[0048] At 25°C, using a high-speed mixer with a stirring speed of 800rpm and a stirring time of 20min, dissolve and disperse 40g of vinyl acetate resin in 49.4g of ethyl acetate and mix well, then add 0.05g of inorganic pigment dispersion aid and continue to stir and mix evenly Then add 10g of aluminum powder, continue to stir and mix evenly; then add 0.55g of adhesion promoter, continue to stir and mix evenly to obtain metal ink composition X1.

Embodiment 2

[0050] This example is used to illustrate the metal ink composition provided by the present invention and its preparation.

[0051]

[0052] At 25°C, using a high-speed mixer, the stirring speed is 500rpm, and the stirring time is 50min. Dissolve and disperse 35g of vinyl acetate resin in a mixture of 19g of acetone and 19.45g of methyl isobutyl ketone. After mixing evenly, add 1.5g of inorganic pigment dispersion aid agent, continue to stir and mix evenly; then add 25g of aluminum powder, continue to stir and mix evenly; then add 0.05g of adhesion promoter, continue to stir and mix evenly, and obtain the metal ink composition X2.

Abstract

The invention discloses a metallic ink composition which contains the following components in parts by weight by taking the total weight of the metallic ink composition as a reference: 15% to 70% of vinyl chloride-acetate copolymer, 2% to 50% of metallic pigment, 0.01% to 5% of inorganic pigment dispersant, 0.01% to 5% of adhesion promoter and 10% to 82% of diluent. The invention further provides a preparation method of the metallic ink composition and an application of the metallic ink composition in food packaging, tobacco packaging and decorative material or safety line production. The metallic ink composition has an effective shielding function, so that the defect of black lines caused by the production of safety lines is overcome. In addition, the metallic ink composition can be applied variously, wherein the formed coating is good in adhesion fastness, acid-base resistance, machine washing resistance, crumpling resistance and heat resistance.

Description

technical field [0001] The invention relates to a metal ink composition and its preparation method and application, in particular to a metal ink composition which can be used in the production of security threads in anti-counterfeiting technology, its preparation method and application. Background technique [0002] Adding security threads to printed matter is an important anti-counterfeiting technique, especially in the printing of banknotes. In the current printing of banknotes in various countries in the world, the production of security threads is multi-layer structure. During the production process of the security thread, some anti-counterfeiting information needs to be covered and hidden. Some of the structural information and the anti-counterfeiting information layer have a darker color. Lines affect the subsequent printing production process of banknote paper and the overall aesthetics of banknotes. [0003] In order to overcome the black line problem caused by the...
