摘要

Printing ink pigments are resin- impregnated with non-drying alkyd resins which are modified with oils, fatty acids, and/or fatty alcohols with an iodine number less than 95, e.g. coconut oil. The pigments may be used in inks for offset printing. The printing ink pigments may be impregnated by applying, for instance spraying, the non-drying alkyd resins in the form of an emulsion or solution during the pigment-drying procedure.
