A process for the production of single- or multiple coated substrates with a binder comprising before adhesion coating slip composition

The invention relates to a coating color composition for application by the curtain coating method of substrates to be coated such. B. raw paper or cardboard is coatable. The substrate, which may be cardboard in the base paper is coated with one or more free-falling liquid curtains, wherein the coating liquid is added to a binder. The binder contains from the group consisting of styrene-butadiene latex binder, styrene-acrylic latex binder, styrene-butadiene-acrylonitrile latex binder, styrene-maleic anhydride binder, and styrene-acrylate-maleic anhydride binder selected, wherein the binder has a particle size comprising of <130 nm.
