As an environmentally friendly ink, first of all, it meets the requirements of environmental protection, and the composition of the ink should be changed, that is, the new ink is formulated with environmentally friendly materials. At present, environmentally friendly inks mainly include water-based inks, UV inks, water-based UV inks and some alcohol-soluble inks.

1. Water-based ink
As a manufacturer of benzidine yellow and permanent orange pigments, you should understand the biggest difference between water-based inks and solvent-based inks, which is that the solvent used is water instead of organic solvents, which significantly reduces VOC emissions, prevents air pollution, and does not affect the human body. Healthy, non-flammable, stable ink, bright colors, non-corrosive plates, simple operation, low price, good post-press adhesion, strong water resistance, and rapid drying, so it is especially suitable for packaging and printed matters such as food, beverages, and medicines. The world-recognized environmentally friendly printing material is also the only ink approved by the US Food and Drug Association among all printing inks.

2. UV curable ink
Ultraviolet light-curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to make the ink film and dry under the irradiation of ultraviolet light. Using different ultraviolet spectra, different energy can be generated to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties.

The main advantages of UV inks are:
(1) No solvent;
(2) Fast drying speed and low energy consumption;
(3) Good gloss and bright colors;
(4) Water resistance, solvent resistance and good wear resistance.

The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into free radicals, and the energy is transferred to photosensitive molecules or photocrosslinking agents, so that the UV ink undergoes a photocuring reaction. At present, UV ink has become a relatively mature ink technology, and its pollutant emission is almost zero. As a manufacturer of benzidine yellow and permanent orange pigments, you should know that in addition to being solvent-free, UV ink also has advantages such as not easy to paste, clear dots, bright and bright ink color, excellent chemical resistance, and low dosage.

3. Water-based UV ink
Water-based UV ink is a new direction of research in the field of UV ink. The viscosity of the prepolymer in ordinary UV ink is generally very large, and it needs to be diluted with a reactive diluent. The currently used diluent acrylate compounds have different degrees of skin irritation and toxicity. Therefore, while developing low-viscosity prepolymers and low-toxicity active diluents, another development direction is to study water-based UV inks, that is, water-based UV inks. and ethanol as diluents. At present, water-based UV ink has been successfully developed and applied in some printing.

In addition, alcohol-soluble ink, which mainly plays a role in flexo printing, is also a kind of ink with little pollution. It is mainly used in the packaging and printing of food, medicine, beverage, tobacco and alcohol, and daily necessities that come into contact with the human body.
