Method for the production of a pulverulent composition containing dyestuff and/or pigment and products obtained using such a composition.

摘要

The invention relates to a method for the production of a pulverulent composition containing dyestuff and/or pigment composition particles, wherein in a plastic dispersed dyestuff and/or pigment composition particles are formed by mixing an aqueous paste containing dyestuff and/or pigment particles in a plastic emulsion, removing water and pulverizing the mass obtained. The dyestuff or pigment is preferably chosen from the spinel pigments, carbon black and organic pigments, and transparent iron oxide; the plastic is preferably chosen from polystyrene, polyethene, polyvinyl chloride and polyvinyl acetate. The particles as obtained can be mixed with a molten wax composition, such that the dyestuff and/or pigment composition particles de-agglomerate, whereafter the mixture is dispersed and left to solidify. The de-agglomerated particles are more particularly smaller than 5 mu .
