Abstract

The present invention relates to a decorative printing ink for gravure printing, its composition is formed from (wt%) 10-50% of oligomer, 10-40% of active diluent, 3-8% of photoinitiator, 0-46% of forming agent whose fineness is less than 10 micrometer, 0.01-1% of retarder and 0-5% of adjuvant. Said UV gravure printing decorative ink possesses reduced oxyinhibition and its solidifying speed is greatly raised, for example, UV light source is 80W / CMX3, at 150M / min. it can be well solidified, and can make cross-hatch with different effects, can print various patterns of imitation metal etching (corning), dioptric, buckle, ice flower and coral form, and its storage stability is good. Said ivnented product is a colorless one, the pigment or colour ink can be added, and the colour pattern can be printed.

Description

technical field [0001] The invention relates to an ink, especially an ink used for gravure printing, which can produce various decorative patterns such as imitation metal etching (sand), refraction, wrinkles, ice flowers, coral, etc. and a strong three-dimensional effect. Patterned UV curable gravure decorative inks. Background technique [0002] At present, the decorative printing of imitation metal etching etc. all adopts the screen printing method, which I have described in detail in the article "UV Screen Printing Decorative Ink" of "Screen Printing" 2000, 6, P26-28. They have been widely used in the packaging of cigarettes, alcohol, cosmetics, and health care products. There are many kinds of UV screen printing decorative inks with single performance, some are troublesome to use, and the production capacity is low. For example, imitation metal etching ink can only be used to print patterns with a sandy surface effect, and there are many types of inks in thick, medium,...
