Abstract

The invention provides transparent pigment slurry and a preparation method thereof. The transparent pigment slurry consists of, by weight, 8-16 parts of pigment color pieces, 4-16 parts of matrix resin, 0.1-1 part of wetting dispersant and 67-68 parts of solvent. Compared with the prior art, the transparent pigment slurry has the advantages that the transparent pigment slurry has very high clarity and can meet the requirement for the clarity of the composite coloring card paper; the flooding problem caused by two or more types of pigment slurry in transfer coatings can be effectively prevented; the compatibility of the pigment slurry with the transfer coatings is better, and the pigment slurry is wide in application range and can be suitable for most of transfer coatings; compared with later coloring, the transparent pigment slurry is suitable for early coloring, the process is simple, it is only needed that a certain proportion of pigment slurry is added into the required transfer coating, and the cost is reduced.

Description

technical field

[0001] The invention relates to a transparent pigment slurry and a preparation method thereof, belonging to the technical field of coatings. Background technique

[0002] At present, transfer coatings are widely used on gold and silver cardboard for packaging of cigarettes, wine boxes, food, gifts, cosmetics, etc., while the pre-coloring technology refers to adding a certain proportion of pigment slurry to the transfer coating to make the transfer coating have different colors , this process not only reduces the technical process of making colored cardboard, but also greatly reduces the cost. However, adding different color pigment pastes to the transfer coating often brings problems such as floating color and blooming, and many pigment pastes have poor clarity. This greatly reduces the aesthetics of colored cardboard, thus restricting the promotion and development of front-color transfer coatings and front-color technology. Contents of the invention [00...
