Organic Pigment For Coating Organic Compounds Made

Hangzhou Fancheng Chemical Co.,Ltd | Updated: Jan 23, 2018

Organic pigments refer to a class of pigments made from organic compounds having a color and a range of other pigment properties. Pigment characteristics include light fastness, water immersion, acid, alkali resistance, organic solvents, heat resistance, crystal stability, dispersibility and hiding power. The difference between an organic pigment and a dye is that it has no affinity for the object to be colored and the object is colored only by adhering the organic pigment to the surface of the object or by mixing it inside the object by means of an adhesive or film-forming substance. Its production of intermediates, production equipment and synthetic processes are similar to the production of dyes, so often organic pigments in the dye industry in the production. Organic pigments compared with the general inorganic pigments, usually have a high color strength, easy to grinding and dispersion of particles, not easy to precipitate, the color is also more bright, but the light, heat resistance, poor weather resistance. Organic pigments are commonly used for the coloring of materials such as inks, coatings, rubber products, plastic products, cultural and educational supplies and building materials.

Organic pigment color varieties of endless changes, colorful, but there is a certain relationship between the various colors, each color can be used to determine the three parameters, that is, color, brightness and saturation. Hue is the color of each other distinguishes each other, depending on the color composition of the light source and the surface of the object emitted by the wavelength of the human eye feel, can distinguish between red, yellow, green, blue, purple and other characteristics. Brightness, also known as brightness, is the surface of the object that changes the degree of brightness of the eigenvalues; by comparing the brightness of the various colors, the color will have this and dark and dark points. Saturation, also known as saturation, is the surface of the object surface color density of the eigenvalues, so that the color has a bright and dark different. Hue, brightness and saturation constitute a three-dimensional, with these three to establish the scale, we can use the figures to measure the color. Nature of the ever-changing color, but the ultra-basic is red, yellow, blue three, known as the primary colors.
