ABSTRACT:
Alkali-soluble resins, their preparation and use are disclosed herein. The resins are carboxylated polyamide/acrylic resins and are synthesized in a two-step fusion process in which a polyamide is first condensed with a carboxylated rosin and this intermediate product is then further condensed with an acrylic or styrene/acrylic copolymer.
