    摘要: A process for preparing pigment concentrates is provided which comprises dispersing a dry pigment in a radiation polymerizable (curable) ethylenically-unsaturated compound. The concentrates to which optionally photoinitiators are added can be used for preparing radiation, preferably ultraviolet radiation, curable printing inks, paints or other coating compositions which in turn are applied in printing processes or in the painting or coating of substrates. The performance enhancement of the cured pigmented inks/paints/coatings include e.g. good tinctorial strength and gloss, as well as surface hardness, good adhesion to substrate and chemical and corrosion resistance.
