An aqueous coating composition with excellent adhesion and waterproof properties is prepared by copolymerizing an alkoxysilane compound, a hydrophilic monomer, and a hydrophobic ethylenically unsaturated monomer at a specific ratio in an organic solvent, and then substituting the organic solvent with aqueous medium. The copolymerization reaction is stable, and the aqueous composition, which is a solution or dispersion, does not contain any substances to deteriorate the water resistance of the resulting film.
Une composition de revêtement aqueuse ayant d'excellentes propriétés d'adhésion et d'imperméabilité est préparée par copolymérisation dans un solvant organique d'un composé d'alcoxysilane, d'un monomère hydrophile et d'un monomère éthylénique insaturé hydrophobe dans un rapport précis, suivie de la substitution du solvant organique par un milieu aqueux. La réaction de copolymérisation est stable, et la composition aqueuse, qui est une solution ou une dispersion, ne contient aucune substance qui affecte la résistance à l'eau de la couche résultante.
