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.

Claim (Index 15):
A process for forming voided latex particles which are non-film-forming, wherein the process comprises contacting multi-stage emulsion polymer particles comprising a core and an outer shell with a swelling agent, wherein:\n the core comprises a hydrophilic component; the outer shell comprises an outer shell polymer having a Tg of at least 45\u00b0 C. and bearing functional groups selected from 1,3-diketo, amino, ureido, urea, fluorocarbon, phosphate, epoxy, hydroxyl, silane, aldehyde, ketone, acetoacetyl, or combinations thereof; and the swelling agent is capable of swelling the core.
