Abstract: A method for reducing the sizes of apertures in a ferrous-metal mask including the steps of coating the mask with a water-basedcoating composition containing a polyvinyl alcohol polymeric material which is water-insolubilized when ferrous or ferric ions are present, and a water-soluble passivator for ferrous-metal surfaces, such as sodium nitrite, and then drying the coating. Inclusion of a passivator in the coating composition reduces or eliminates the formation of localized coating discontinuities, usually comet shaped, in the coating.

Abstract: A process for coating a flatlike surface, such as the inner surface of the viewing panel of a cathode ray tube, comprising A. SLOWLY ROTATING THE SURFACE, FACING DOWNWARD, ABOUT AN AXIS THAT IS SUBSTANTIALLY NORMAL TO THE SURFACE, B. PROJECTING A STREAM OF LIQUID COATING MATERIAL IN A TRAJECTORY TO CONTACT THE ROTATING SURFACE SUBSTANTIALLY TANGENTIALLY AND THEN TO PASS ALONG THE SURFACE THROUGH THE AXIS, C. AND THEN PERMITTING EXCESS COATING MATERIAL TO DRAIN FROM THE ROTATING SURFACE.
