| 摘要 |
This invention relates to a process for preparing aqueous blends of sulfo-polyesters and solid acrylic resins without volatile organic compounds (VOC's) and surfactants. More specifically, the acrylic resins are characterized by an inverse relationship between the molecular weight and acid number of the resin, and the sulfo-polyesters contain at least 12 mole percent of a difunctional sulfomonomer. The aqueous sulfo-polyester/acrylic resin blends of the present invention are useful in inks, overprint varnishes, primers, paints, and coatings.
