    Abstract: An aqueous coating composition (especially a paint intended for application under ambient conditions) comprising silanol-functionalised resin and particulate non-film-forming solids such as pigments and extenders where the improvement lies in using the silanol-functionalised resin in acidic aqueous solution together with a high pigment volume concentration (PVC) of at least 65% so that dried coatings obtained from the composition have the high opacities characteristic of high PVC, yet the resin is sufficiently crosslinked to give good abrasion resistance with any tendency to excessive cohesion in the coating being offset by the air voids and other discontinuities created by the high PVC.
