Embodiment 1

[0023] The yellow pigment is transparent yellow 4400T from DIC Company, the electroplating silver paste is ultra-thin non-leafing super bright aluminum silver paste of 1500 mesh, the ester-soluble polyurethane is PU-70 from Fangchuan Company, and the ketone resin is CF-120 from Crefu Company Aldehyde and ketone resins and additives are selected from DuPont's IA10 coupling agent, environmentally friendly triester citrate, and Clariant's 3620 polyethylene micropowder wax.

[0024] A kind of preparation method of gravure ester-soluble golden ink, the weight percent of its raw material is:

[0025] 6 parts of transparent yellow 4400T (DIC), 11 parts of electroplated silver 41-0010 (Ciba), 25 parts of ester-soluble polyurethane resin liquid PU70 (Fangchuan), 4 parts of aldehyde and ketone resin CF120 (Crifu), polyethylene wax 3620 ( Clariant) 1.5 parts, IA10 (DuPont) 0.5 parts, 2 parts of triester citrate, 18 parts of ethyl acetate, 32 parts of n-propyl acetate.

[0026] The prepa...

Embodiment 2

[0034] The difference from Example 1 is that the weight percent of its raw materials is: 7 parts of transparent yellow 4400T (DIC), 8 parts of electroplated silver 41-0010 (Ciba), 28 parts of ester-soluble polyurethane resin liquid PU70 (Arakawa), aldehyde Ketone resin CF120 (Coriver) 2 parts, polyethylene wax 3620 (Clariant) 0.3 parts, IA10 (DuPont) 0.2 parts, triester citrate 0.5 parts, ethyl acetate 20 parts, n-propyl acetate 30 parts.

[0035] The preparation method process of above-mentioned gravure ester-soluble golden ink is as follows:

[0036] (1) Use the following components by weight: 6 parts of ethyl acetate, 2 parts of aldehyde and ketone resin, stir and dissolve to form a polyketone solution;

[0037] (2) Weigh the following components by weight: 28 parts of ester-soluble polyurethane liquid, 7 parts of transparent yellow, 0.3 parts of polyethylene wax, 0.2 parts of A-10 coupling agent, 0.5 parts of triester citrate, n-propyl acetate Add 20 parts into the above ...

Embodiment 3

[0043] The difference from Example 1 is that the weight percent of its raw materials is: 8 parts of transparent yellow 4400T (DIC), 13 parts of electroplated silver 41-0010 (Ciba), 30 parts of ester-soluble polyurethane resin liquid PU70 (Fangchuan), aldehyde Ketone resin CF120 (Coriver) 5 parts, polyethylene wax 3620 (Clariant) 2 parts, IA10 (DuPont) 0.5 parts, triester citrate 2.5 parts, ethyl acetate 16 parts, n-propyl acetate 23 parts.

[0044] The preparation method process of above-mentioned gravure ester-soluble golden ink is as follows:

[0045] (1) Use the following components by weight: 6 parts of ethyl acetate, 5 parts of aldehyde and ketone resin, stir and dissolve to form a polyketone solution;

[0046] (2) Weigh the following components by weight: 30 parts of ester-soluble polyurethane liquid, 8 parts of 4400T yellow pigment, 1.5 parts of polyethylene wax, 0.5 parts of A-10 coupling agent, 2.5 parts of citrate triester, n-propyl acetate Add 13 parts of ester to ...

Abstract

The invention provides gravure lipophilic golden ink and a preparation method thereof. The ink is prepared from the following components in parts by weight: 6-8 parts of yellow pigment, 8-13 parts of electroplated silver, 25-30 parts of lipophilic polyurethane resin liquid, 2-5 parts of ketone-aldehyde resin, 1-5 parts of auxiliary and 39-50 parts of mixed solvent. According to the gravure lipophilic golden ink and the preparation method thereof, each index can reach the specified standard, and compared with ink prepared from bronze powder, the gravure lipophilic golden ink has the advantages of excellent metal effect and storage stability.

Description

technical field [0001] The invention relates to an inner or outer printing ink for PET, OPP, NY and other films, which can be used for printing cosmetics, dried fruits, food, etc., in particular to a gravure ester-soluble golden ink and a preparation method thereof. Background technique [0002] The main components of gravure printing ink are colored substances (pigments) and linking materials. Among them, the colored substance plays the role of color development, and the image is displayed on the substrate by contrasting with the color of the substrate. Only when the proportion of each component of the ink is properly adjusted can the printing suitability and performance of the ink be achieved, and the printing ink can be well matched with the printing plate, printing machine and printing material, so that the printing process can be carried out smoothly. [0003] At present, the common gravure gold inks used for gold pigments mostly use copper gold powder as the color mat...
