Abstract

PURPOSE: To obtain a conc. dye composition capable of giving uniform colored plastics, by fixing meltable dye powder on plastic particles mixed with the powder.
CONSTITUTION: A powdered meltable dye is mixed with plastic particles having a higher melting point, and fixed on the particle surfaces at a temperature of the formula (Tm-t)WTm (Tm is the melting point of the dye; 0≤t≤4, preferably 0≤t≤2)°C to give a conc. dye composition. The product is a composition comprising powder dye extended with plastic particles, with a dye content ≤25wt%. An anthraquinone dye, e.g. 1,4-bis (2',4',6'-triethylanilino)anthraquinone, may be cited as the dye.
