Abstract: Self-coating or self-layering lacquer systems from at least two different resins, oligomers, or polymers, which are emulsifiable or dispersible in water, have different surface tensions, and form self-layering phases. After the application, the phases separate into the components of the formulation.

Abstract: Binders compriseA) an aminotriazine derivative in which the primary amino groups of the triazine are methylolated on average with at least one mole of formaldehyde per mole of primary amino groups, and these methylol groups are etherified on average with at least 0.5 mol of primary alcohol per mole of methylol group and the primary alcohols are a mixture containinga) 0.5-99.5 mol % of a C.sub.1 -C.sub.4 -alkanol andb) 99.5-0.5 mol % of an alcohol of the formulaR.sup.1 --O--?R.sup.2 --O!.sub.n --R.sup.3 --OH I,in which R.sup.1 is C.sub.1 -C.sub.24 -alkyl or C.sub.6 -C.sub.12 -aryl which may be unsubstituted or substituted by from one to three C.sub.1 -C.sub.8 -alkyl groups, and R.sup.2 and R.sup.3 independently of one another are C.sub.2 -C.sub.8 -alkylene and n is an integer from 1 to 100, or of a mixture of higher-boiling alcohols having a boiling point of above 120.degree.
