ANIONIC POLYMER DISPERSION CONTAINING NONVOLATILE PROTONATED AMINO COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an anionic polymer dispersion which gives initial water resistance to an exterior coating. SOLUTION: The polymer dispersion comprises an anionic aqueous polymer dispersion used as a binder of a coating or plaster on a base material exposed to weather, has anion groups neutralized with a volatile base, and contains a nonvolatile amino compound having at least two amino groups at least 40% of which are protonated.
