Abstract
An aqueous coating material preparable by mixing with one another (A1) at least one substantially water-free base color comprising (a11) at least one optionally water-soluble or -dispersible binder, (a12) at least one color and/or effect pigment, and (a13) at least one optionally water-miscible organic solvent; (A2) at least one aqueous base color comprising (a21) at least one water-soluble or -dispersible binder, (a22) at least one color pigment, and (a23) water; and (B) at least one aqueous pigment-free mixing varnish comprising (b1) at least one water-soluble or -dispersible binder and (b2) water; and also, if desired, comprising (C) an aqueous medium comprising (c1) a rheology control additive; and also a modular system for preparing aqueous coating materials, comprising (I) at least one substantially water-free color and/or effect module, comprising at least one base color (A1), (II) at least one aqueous color module comprising at least one base color (A2), and (III) at least one aqueous, pigment-free mixing varnish module comprising at least one aqueous, pigment-free mixing varnish (B), and if desired (IV) at least one rheology module.
