Abstract

The invention relates to carving gravure printing ink applicable to a non-absorbent printed material and connecting materials of the carving gravure printing ink. The carving gravure printing ink comprises the following components in percentage by weight: 1 to 66 percent of connecting material A, 1 to 33 percent of connecting material B and 1 to 98 percent of alkyd resin C, wherein the connecting material A comprises the following components in part by weight: 40 to 60 parts of soybean oil, 15 to 40 parts of dry vegetable oil and 20 to 50 parts of high-acid-value rosin modified phenolic resin; the connecting material B comprises the following components in part by weight: 40 to 60 parts of soybean oil, 10 to 40 parts of dry vegetable oil, 20 to 50 parts of pure phenolic resin, 0.1 to 5 parts of unsaturated polymer and 0.1 to 5 parts of gelatinizing agent; and the alkyd resin C is long oil-length soya alkyd resin, medium oil-length soya alkyd resin or short oil-length soya alkyd resin. The carving gravure printing ink and the connecting materials of the carving gravure printing ink solve the problem that the conventional common carving gravure printing ink and the connecting materials thereof do not adapt to the non-absorbent printed material and have the advantage of high adhesiveness on the non-absorbent printed material.

Description

technical field [0001] The invention relates to an engraving gravure printing ink and its connecting material suitable for non-absorbing substrates. Background technique [0002] Engraving gravure ink is an important anti-counterfeiting ink in banknote printing, and the ink is generally printed on absorbent substrates. Therefore, the design of engraving gravure ink and its binder considers its printability, and its drying method is mainly volatilization and penetration. The volatilization mainly depends on the low boiling point solvent in the engraving gravure printing ink and its binder; the penetration mainly depends on the high boiling point solvent in the engraving gravure printing ink and its binder and other unvolatile solvents in the ink. The volatilization and penetration can make the engraving gravure ink fast fix on the surface of the substrate, and the penetration can make the engraving gravure ink anchor on the surface of the substrate, and its adhesion fastness...
