摘要： The present invention provides a water-borne coating system comprising a top-coat polymer and a base-coat polymer each in dispersion, and including a component that results in increased mobility of the top-coat polymer relative to the base-coat polymer. Preferably, excess surfactant is used to increase the mobility of the top-coat polymer by the formation of micelles, and the curing agent acts to aggregate the base-coat polymer before the curing reaction and whilst segregation occurs. Suitable surfactants include ethylene oxide copolymers and ethoxylated nonylphenol. Preferably non-ionic stabilisation is used for the top-coat dispersion.

摘要： A surface active agent contains at least one radical generator group in each of its lipophilic and hydrophilic moieties. A water-in-oil dispersion or oil-in-water dispersions contains a first polymerisable monomer dissolved in the oil phase and a second monomer dissolved in the oil phase and a second monomer dissolved in the aqueous phase. A surface active agent as defined above is dispersed across the interface of the oil phase and the aqueous phase with its lipophilic moiety well solvated by the oil phase and its hydrophilic moiety well solvated by the aqueous phase. A segmented polymer comprising such a surface active agent having at least one lipophilic polymer segment attached to its lipophilic moiety and at least one hydrophilic polymer segment attached to its hydrophilic moiety can be formed from the dispersion.
