How to distinguish between color paste, color essence, color masterbatch, pigments
Color paste, as the name suggests, is a pigment concentrated pulp, is the use of different pigments, through the pigment surface treatment, surface wrapping and other technologies, developed through rigorous processing technology. According to the different solvents used in color paste, color paste is divided into water-based color paste, oil-based color paste, water-oil general-purpose color paste, etc.; according to the different uses of color paste is divided into paint color paste, adhesive tape color paste, papermaking color paste, textile color paste, machinery color paste, toy color paste, latex products color paste, etc.; according to the different tools for the use of color paste, people simply divided into the factory color paste and machine color paste and so on. Color paste in the natural world in concert with the dress up the whole world, small to dress up, daily use, toys, etc., large to bridges, housing construction, etc., is not to show the colorful colors.
With the rapid development of construction and industry, including hotels, commercial, landscape, transportation and other color paste areas rarely designed to the field have been significantly into the color paste market development scope, is moving towards a holistic, energy-saving development trend, of course, this is mainly manifested in the rapid rise of the color paste manufacturers, driven by the entire color paste industry tends to be highly efficient, low-carbon development.
Water-based color paste for coloring, its application areas are very broad, including paint, leather, printing, paper, latex, textile and other industries, the main service object is the paint industry.
Now the industry class in the “oil to water” water-based color paste will slowly replace the original industries of the oil-based color paste, oil will become a thing of the past, water-based environmental protection industry will become the subject of technical exchanges in the industry, to water-based environmental protection is the transformation of the coatings industry is the future expansion of the direction of progress.

Color essence
Metal complex dyes, also called transparent dyes, commonly known as color essence or color powder, is a kind of dyes that can be dissolved with solvents, and the compatibility with various resins is very good, so its application range is very wide. Due to the special nature of the complex structure of metal complex dyes, which is different from general organic pigments and traditional azo dyes, it has higher gloss and transparency, better weather resistance and stronger firmness; compared with inorganic pigments, metal complex dyes have the properties of easy dispersion, easy penetration, easy coloring, brilliant color and good transparency effect. It is mainly used in the following industries:
1) Metal complex dyes for solvent ink;
2) Metal complex dyes for printing inks for aluminum foil;
3) Metal complex dyes for printing inks used for other paper or metal surfaces (e.g. screen printing);
4) Metal complexing dyes for wood coatings;
5) metal complex dyes for aluminum foil coloring (e.g. stamping materials);
(6) Metal complex dyes for transparent coloring of metals (e.g. low-temperature baking paint for interior decorations);
(7) Metal complex dyes for special coatings;
(8) Metal complex dyes for ballpoint pens and various stationery inks;
(9) Metal complex dyes for surface coloring of plastic products (e.g. vacuum plating, etc.);
(10) Metal complex dyes for surface coloring of natural and synthetic leather;
(11) Metal complex dyes for shoe polish coloring.
(12) Metal complex dyes for coloring lamp products.
Solvent color essence is a kind of dye that can be dissolved in organic solvents such as aromatics, esters, styrene, methyl methyl propionate, etc. (almost insoluble in water).
Color Master Batch
Color Master Batch, also known as Color Seed, is a new type of colorant for polymer materials, also known as Pigment Preparation. Masterbatch is mainly used in plastics. Color masterbatch is composed of three basic elements: pigment or dye, carrier and additives. It is an aggregate made by uniformly attaching an extraordinary amount of pigment to the resin, which can be called Pigment Concentration, so its coloring power is higher than that of the pigment itself. When processing, a small amount of masterbatch and uncolored resin can be mixed to achieve the designed pigment concentration of coloring resin or products.
Colors
The food coloring that we most often hear about is a kind of pigment, i.e., food additives that can be consumed by human beings in moderation and can make food change its original color to a certain extent. Like food flavors, food colors are classified into two types: natural and synthetic.

The color of food is an important factor in the sensory quality of food. Food coloring, a food additive, is often used in food preparation. There are two main types of food coloring: natural food coloring and synthetic food coloring. Before the British invented the first synthetic food coloring, aniline violet, in 1850, people used natural colors to color. As early as before the 10th century A.D., the ancients began to use plant-based natural pigments to color food, and the earliest use of coloring was by the Alexians of Great Britain, when they used chypre plant pigments to make rose
