Abstract
A pigment composition is disclosed, obtained from intaglio or engraved steel die printing ink wastes. The wastes containing pigment, ink resins, extenders, and other minor components, are dried, ground and sieved to give a dry pigment composition. This pigment composition is optionally blended with plasticizers to give a pasty composition. These compositions are useful to color and plasticize synthetic plastics materials such as sheetings, PVC leather and films.
