    Abstract: The present invention provides novel compositions prepared from a first oligomer containing reactive functional groups capable of reaction at effective rates (at normal processing temperatures) with a co-reactive second component oligomer possessing functionality that is complementary to that of the first oligomer. The compositions may be used as coatings, including hard surface coatings, clear coatings, powder coatings and pattern coatings; as adhesives, including pressure sensitive adhesives and hot melt adhesives; as sealants; as optical coatings; as blown microfibers (BMF); as high refractive index optical materials; as barrier films; in microreplication; as low adhesion backsizes, (LABs) and as release coatings.

    Abstract: An aqueous protective coating composition particularly useful for can coatings based on a polymeric binder comprises diepoxide crosslinked microgel particles. The microgel polymer is produced by dispersing into water a carboxyl functional acrylic-epoxy copolymer and combined with a carboxyl functional latex polymer along with a low molecular weight diepoxide, followed by coreaction and crosslinking between the carboxyl polymers and the diepoxide to form stable aqueous dispersed microgel particles. In a preferred aspect of the invention, the carboxyl latex polymer is a swollen latex polymer.
