Dyes do not dissolve in water, but partially dissolve in some organic solvents, fats and petroleum products. In polymer products colored with pigments, the color effect is achieved due to the relationship between absorption, reflection and scattering of light on the surface of crystalline pigment particles (Fig. fig a. and b). Fig. The difference between the optical effects of pigments (a) and dyes (b) in a colored polymer Usually, the use of dyes is limited to transparent (amorphous) polymers, for example, PS, PMMA, PC and PET at a concentration of 0.01 to 0.1%, depending on the required color intensity.
