Abstract

A pigment such as carbon black or alumina hydrate is wetted with a wetting agent such as an organic or inorganic acid, an inorganic base, a ketone, an alcohol or a hydrocarbon, the agent containing a dye if alumina hydrate is used as the pigment, and the wetting pigment is suspended in a hydrocarbon carrier liquid which contains a dissolved resin, wax or linseed oil the dissolved resin, wax or oil being adsorbed by the wetted pigment.
