Use of natural pigments:
Natural pigment is an insoluble organic substance, which is generally included to the substrate in a very dispersed state to make the substrate colored. Natural and organic pigments are widely utilized in the colouring of inks, paints, coatings, artificial fibers, as properly as textile pigment printing, plastics, rubber, leather-based and so on. The output of organic pigments accounts for about a quarter of the total output of dyes.
