The dyes distinguish themselves by high color strength and subsequent efficiency. They result in pure vivid shades. They can be mixed freely with one another or with organic or inorganic pigments. Each and every desired hue may be attained. For opaque colorations a scattering white or chromatic pigment is added. Application Sometimes, the shade of a coloration is influenced by the opacity or the inherent color of a polymer. A shade in standard polystyrene may be different from that in polycarbonate. Important factors are the solubility characteristics of the dye and any chemical interactions between the dye and the polymer. The solvatochromy (solubilized chromatic substances display different color hues in media of different polarity) plays an important role. To ensure optimum fluorescence when transparent plastics are colored with Thermoplast F Yellow 084, attention must be paid to the concentration of the dye and the thickness of the finished article. Maximum fluorescence is attained at a concentration of approx. 0.01 % Thermoplast F Yellow 084 in specimens of 2 mm thickness and at approx. 0.05 % in 0.2 mm specimens. Excessive amounts of dye quench the fluorescence. ABS/ASA ABS PMMA PC PA PETP CA/CAB UP
