Abstract
PURPOSE: To provide a color concentrate compsn. which is suitable for use in coloring of thermoplasting resins such as ABS resins and produces a molded article having uniform color and gloss without lowering physical properties, by a method wherein a colorant and optionally a thermoplastic resin are blended with a molten rubber.
CONSTITUTION: (I) more than 25wt% of a molten rubber, e.g., obtd. by heating natural rubber or valcanized (or unvulcanized) synthetic rubber together with oils to decompose it and (II) less than 75wt% of a colorant and if necessary, (iii) 1W40wt% of a thermoplastic resin are kneaded by means of an extruder, etc. to obtain a color concentrate compsn. (A). The compsn. (A) is mixed with an unpigmented resin in a mixing ratio of the compsn. to the resin of 1: less than 49 (by weight) by means a super mixer, etc. The mixt. is molded to obtain a pigmented molded article.
EFFECT: The process excels in cost and workability.
