Abstract
Abstract Solid particulate coloring composition comprising a number of components including at least one component being liquid at ambient temperature obtained by mixing a molten carrier material which is solid at ambient temperature; one or more of said components which are liquid at ambient temperature, a pigment of dyestuff, and a particulate material having a large specific surface, preferably a synthetic silica material and dividing said mixture into particles being solid under ambient conditions.
