AQUEOUS DISPERSION, METHOD FOR PRODUCING THE SAME, AND COATED SUBSTRATE

摘要

Disclosed is a method for producing an aqueous dispersion, which includes using ammonia (B) to neutralize and disperse an ethylene/methacrylic acid copolymer (A) in an aqueous medium in the presence of monohydric alcohol (C) containing 3 or more carbon atoms. The process allows for dispersion with ammonia and production of a low viscosity aqueous dispersion with better dispersibility and higher uniformity of the dispersed particles than a conventional process with ammonia neutralization.
