Abstract

The invention relates to gravure pearlescent printing ink with an excellent storage property and a preparation method therefor. The gravure pearlescent printing ink is prepared from the following ingredients, by weight, 10-30% of pearlescent pigment, 30-60% of connecting material and 20-40% of solvent. Firstly, the quantitative solvent is placed in a stirring barrel, the quantitative pearlescent pigment is added into the solvent with stirring until the pearlescent pigment is dissolved fully and a pearlescent solution is obtained;the quantitative connecting material is added into the a pearlescent solution with stirring, and pearlescent printing ink with uniform dispersion is obtained after uniform stirring. The pearlescent printing ink has a better anti-precipitation property than normal pearlescent printing ink through improvement of the connecting material resin in the pearlescent printing ink, and the problem is solved that the problem pearlescent printing ink is easy to discard after long-time storage.

Description

technical field [0001] The invention relates to a pearlescent ink, in particular to a gravure pearlescent ink with excellent storage properties and a preparation method thereof. Background technique [0002] Pearlescent ink is prepared from pearlescent pigments, synthetic resins, organic solvents and additives. Pearlescent ink has a unique printing effect, strong three-dimensional effect and artistic appeal, making it more and more popular in packaging paper printing. Pearlescent ink has incomparable characteristics of gold and silver inks, because pearlescent printing has bright visual effects, it will change into dazzling colors under sunlight, so it is widely used on paper, plastic, metal and other substrates, especially in Cosmetics, tobacco and wine packaging, invitation cards, birthday card products and other packaging aspects. [0003] Since many companies such as DuPont of the United States and Toyota Corporation of Japan successively launched titanium dioxide-coat...
