Abstract
Abstract This invention relates to a novel metal pigment product which is comprised of metal particles, terpene phenol resin and polyethylene resin and the process for making them. The compositions and products made from them, are stable even after storage at room temperature or being subjected to a heat aging test. Films or coatings made from these products have a uniform dispersion of the metal particles.
