Abstract
Powder coating compositions are prepared by first forming a dispersion in water of a complex polyhydroxy polyether resin using as the dispersant an inorganic or organic base salt of a polymeric carboxylic acid having an acid value before salting of at least 50, acidifying the dispersion and then isolating and drying the precipitated fine particle size resin. Such resins in this finely divided form find particular utility as powder coatings for metallic articles.
