Abstract

The wet adhesion of a coating composition may be improved through the use of voided latex particles as opacifying agents which contain a hollow interior as well as an outer shell of a polymer containing functional groups such as amino, 1,3-diketo, urea or ureido. Other types of functional groups may be introduced to the outer shell polymer in order to vary other desired characteristics of the coating. The voided latex particles are non-film-forming.
