Application fields and characteristics of organic pigments for various inks

Foreword: Evaluation of the application performance of organic pigments for inks.

1.

Rosin-modified phenolic resins are mainly used in offset printing inks.

2.

Because the physical and chemical properties of the binder system made of resin and solvent are quite different, the evaluation of solvent-based ink pigments needs to be more targeted

3.

Pigments for water-based inks will definitely become a trend, because this is a requirement for environmental protection and the top priority in terms of waste of social resources.

4.

The screen printing ink needs to be printed on irregular objects, showing different tones and then highlighting.
This requires Siyin ink to have the characteristics of bright color, solvent resistance, and water insolubility.
For these characteristics, the specific requirements for pigments are The fineness of the pigment is good, the dispersion is good, it can fully integrate the solvent, the solvent resistance is also strong, and the color is bright, because the color of the silk screen printing ink is the most among all the inks, such as medium yellow, bright red, original yellow, bright red, violet, pink.
etc.
, these pigments must meet the requirements
.

Summary: Pigments for inks are divided into organic pigments for inks and inorganic pigments for inks.
Organic pigments are divided into yellow pigments for inks, red pigments for inks, blue pigments for inks and green pigments for inks, each of which has different properties.
This has brought a lot of troubles to ink producers.
For example, the products produced by domestic organic pigment manufacturers all have a focus, for example, some focus on ink, some plastics, some coatings, the same product is the same In the field of application, how to grasp the performance of the pigment is related to the scope of application of the pigment for ink
