Color, pigments synthetic

In PVC, most benzimidazolone pigments are heat stable up to 220°C. They have excellent to outstanding lightfastness. Some representatives are very weather-fast in impact resistant PVC types and in rigid PVC and even withstand long-term weathering. Various benzimidazolone pigments are used, for instance by the automobile industry, in PVC plastisols to lend color to synthetic leather.

Various natural pigment classes, such as llavonoids, an-thocyanins, carotenoids, chlorophylls and chlorophyll derivatives, porphyrins, quinones, anthraqinones, be-talains, and so forth are abundant in many famihes of the vegetable and animal kingdoms. As consumers generally dislike the color of synthetic dyes, the concentration and composition of pigments in foods and food products exert a considerable impact on the consumer acceptance and, consequently, on the commercial value of the products. It has been proven many times that one of the main properties employed for the commercial evaluation of the quahty of products is their color that is, an adequate color is an important requirement of marketabihty. 

The production of white coatings or bulk white solids and the lightening of formulations with colored pigments is currently only possible by pigmentation with white pigments. All white pigments are produced synthetically. 

Pigment. Synthetic organic pigments are inert, stable, coloured substances insoluble in water and organic solvents, such as the oils commonly used as vehicles in paint manufacture. They are used also in the mass coloration of plastics. Physical form is of paramount importance in ensuring maximum colouring power and reflectance.
