I、Product presentation

•        Organic pigments are insoluble organic compounds that are typically added to substrates in a highly dispersed state to color them.

•        The fundamental difference between it and dyes is that dyes can dissolve in the dyeing medium used, while pigments are neither soluble in the medium in which they are used nor in the substrate being colored.

•        Many pigments and dyes have the same chemical structure and can be converted to each other using different methods. For example, some reducing dyes and sulfurized reducing dyes can be used as fiber dyes if they are reduced to a cryptochrome; If not restored, it can be used as a pigment for advanced inks.

•        Organic pigments are widely used for coloring inks, paints, coatings, synthetic fibers, as well as for pigment printing of fabrics, coloring of plastics, rubber, leather, etc. Among them, ink pigments are used the most.

•        The production of organic pigments accounts for about a quarter of the total dye production.

II、Product characteristics

•        Weather resistance：

The weather resistance is related to the amount of colorants used and the duration of light exposure. Products such as phthalocyanine blue, phthalocyanine green, and sun resistant red powder are more durable.

•        Resistant migration：

The performance of colorants migrating from the interior of plastic to the surface or from one plastic to another through an interface. It is related to the application concentration and processing temperature.

•        Easy to disperse：

The ability to disperse evenly into plastic during the coloring process.

The ability to reduce its aggregate and aggregate size to an ideal size after wetting.

•        Stability

At a certain processing temperature and for a certain period of time, there is no significant change in color, coloring power, or performance.

III、The difference between inorganic pigments and organic pigments

Organic pigments are colored compounds with various application characteristics that meet the requirements by coloring substances in the form of insoluble fine particles in the coloring medium.

Compared with inorganic colored compounds, it has a wide variety of chromatographic and commercial specific dosage forms, bright colors, high coloring strength, and high-end organic pigments with excellent durability, non toxicity, or low toxicity.

Widely used in industrial coatings, printing inks, resin plastic coloring, and textile printing fields.
