PROCESS FOR PRODUCING FOAMED WALLPAPERS

摘要

The invention relates to a process for producing a foamed coating on a substrate in the form of a web, where the substrate is entirely or to some extent coated with a coating composition, the applied layer is dried at a temperature above 70°C, and the coating composition is applied in the form of foam, where an aqueous coating composition is used, comprising polymers selected from poly(meth)acrylates, maleate polymers or ethylene-vinyl acetate polymers, and the coating composition is foamed by an inert gas that has been introduced.
