Meaning of organic pigments: A class of pigments made of organic compounds that have color and a range of other pigment properties. Pigment properties include light fastness, water immersion resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersibility and hiding power.

Pigment properties include light fastness, water immersion resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersibility and hiding power. The difference between organic pigments and dyes is that they have no affinity with the object to be colored, and only the organic pigments are attached to the surface of the object through adhesives or film-forming substances, or mixed inside the object to color the object. Colorize objects.
Organic pigments are a class of pigments made of organic compounds that have color and a range of other pigment properties. Pigment properties include light fastness, water immersion resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersibility and hiding power. The difference between organic pigments and dyes is that they have no affinity with the object to be colored, and only the organic pigments are attached to the surface of the object through adhesives or film-forming substances, or mixed inside the object to color the object. The intermediates, production equipment and synthesis process required for its production are similar to the production of dyes, so organic pigments are often organized in the dye industry. Compared with general inorganic pigments, organic pigments usually have higher tinting strength, the particles are easy to grind and disperse, not easy to precipitate, and the color is brighter, but the light fastness, heat resistance and weather resistance are poor. Organic pigments are widely used in the coloring of materials such as inks, coatings, rubber products, plastic products, stationery and building materials. The coloring of the coloring material.
The varieties of organic pigment colors are endless and colorful, but there is a certain internal relationship between various colors. Each color can be determined by 3 parameters, namely hue, lightness and saturation. Hue is a feature that distinguishes colors from each other. It is determined by the chromatographic composition of the light source and the perception of each wavelength emitted by the surface of the object to the human eye. It can distinguish red, yellow, green, blue, purple and other characteristics. Lightness, also known as brightness, is a characteristic value that represents the change in the degree of light and dark on the surface of an object; by comparing the lightness of various colors, the color can be divided into light and dark. Saturation, also known as chroma, is a characteristic value that indicates the shade of color on the surface of an object, making the color brighter and darker. Hue, lightness, and saturation form a solid, and using these three to establish a scale, we can measure color numerically. The colors in nature are ever-changing, but the basic three are red, yellow and blue, which are called primary colors. The three are called yellow, blue-red, yellow, and blue, and they are called primary colors. Three, called primary colors. say
Inside the body, colorize the object. Make primary colors.
It makes the colors bright and dark. Hue, lightness, and saturation form a solid, and using these three to establish a scale, we can measure color numerically. The colors in nature are ever-changing, but the basic three are red, yellow and blue, which are called primary colors.
