ABSTRACT WATER-DILUTABLE AQUEOUS POLYMER PAINTS Aqueous coating compositions comprise a polymer of defined molecular weight which contains either anionisable or cationisable groups and also certain defined non-ionisable water- soluble moieties (derived for example from poly- ethylene glycol), water, optionally an organic coupling solvent and optionally either base or acid. The presence in the polymer of regularly distributed ionisable groups and non-ionisable water-soluble moieties enables the selection of aqueous polymer solutions for use in coating compositions which, on dilution, show a regular relationship between viscosity and solids content. The polymer solutions are particularly useful in the formulation of paints.
