The substrate, which can be cardboard or base paper, is coated with one or several free-falling liquid curtains. The binding agent is added to the coating fluid. The binding agent is selected from the group containing styrol-butadiene latex binders, styrol- acrylate-latex binders, styrol-butadiene-acrylnitrile latex binders, styrol- maleic acid anhydride binders and styrol-acrylate-maleic acid anhydride binders. The binding agent has a particle size of < 130 nm.
Composition d'enduit colorée qui peut être appliquée sur des substrats à recouvrir tels que par exemple du papier brut ou du carton, selon un procédé d'enduction à rideau liquide. Le substrat, pour lequel il peut s'agir de papier brut ou de carton, est enduit à l'aide d'un ou plusieurs rideaux liquides tombant librement, un liant étant ajouté au liquide d'enduction.
