PURPOSE: The titled composition that is obtained by irradiating a mixture of a specific saturated polymer insoluble in water and a specific quaternary salt with electron rays, thus having fine particle sizes and giving aqueous dispersion with high water and solvent resistances, good physical properties and chemical stability.
CONSTITUTION: A mixture consisting of (A) 85W98wt% of a saturated polymer resulting from addition or condensation reaction between (i) an organic compound bearing alcoholic or phenolic hydroxyls and (ii) another organic compound bearing groups selected from carboxyl, isocyanate and aldehyde, such as a saturated polyester resin obtained from a saturated dihydric alcohol and a saturated dibasic acid and (B) 2W15wt% of an α,β-unsaturated carboxyl-containing quaternary salt having one amine nitrogen atom which can be converted into the quaternary form in the ester residue such as methacryloyloxyethyl triethyl ammonium chloride is irradiated with electron rays to give the objective composition.
