Abstract

The invention relates to intaglio compound printing ink, in particular relates to lipophilic polyurethane printing ink and a preparation method thereof, and belongs to the field of printing ink. In order to overcome the technical defects of big smell, more residual solvent and poor resin fastness of the printing ink in the prior art, the invention provides the lipophilic intaglio compound printing ink and the preparation method thereof. The lipophilic intaglio compound printing ink has excellent early dry performance and tinting strength, is very suitable for automatic packaging and has a good industry popularization value, and the friction coefficient is between 0.6 and 0.7.

Description

technical field [0001] The invention relates to a gravure composite ink, in particular to a Ester soluble The invention discloses a gravure composite ink and a preparation method thereof, which belong to the field of printing ink. Background technique [0002] With the continuous improvement of people's requirements for the quality of life and the living and development environment, the voice of "green packaging materials" in the packaging market is getting higher and higher, that is, to improve environmental protection performance, choose energy-saving, low-consumption, non-toxic, non-polluting, and easy-to-degrade non-toxic materials. Hazardous packaging materials. "Green packaging materials" is the development trend of packaging and printing materials in the future, and people pay more and more attention to them. Printing ink is one of the most polluted raw materials in packaging materials. "Green packaging materials" call for environmentally friendly ink products to mee...
