ABSTRACT:
A crosslinkable aqueous polyester-containing emulsion and a process for preparing the same. The emulsion is obtained by polymerizing unsaturated monomers of acrylic, using a crosslinkable, sulfonated polyester emulsifier having an acid number less than 80 mg KOH/g and an intrinsic viscosity greater than 0.1 dl/g as an emulsifier. The emulsion has the chemical characteristics of both polyester and acrylic resin, i.e. has low volatile organic compounds, good mechanical stability, and good storage stability. Since the emulsion is crosslinkable, a film formed by the emulsion has excellent adhesion, water and heat resistance. Thus, the emulsion is useful for coating and printing on Nylon, PET, OPP films, as well as for high performance industrial surface coating and adhesion for which good heat-, water-, and weather-resistance are required.
