Abstract
Abstract A coating composition low in volatile organic solvents comprising a monodispersed acrylic polymer solutions containing supercritical, near supercritical or subcritical fluids as a diluent therein. Desirably, the monodispersed acrylic polymer has a molecular weight such that it is, as such, a polymeric coating vehicle.
