PAT 87 128 February 10th 87 Aqueous two-component paints for one-coat coating of high-resistant finishing sheeting and continuous edging Abstract The invention relates to aqueous two-component paints containing customary additives and, if appropriate, pigments, for one-coat coating of finishing sheeting and continuous edging, characterized in that the paints con- taining as paint component (I) (A) 40 to 85% by weight, preferably 60 to 85% by weight, of an aqueous dispersion of a self-crosslinking poly- acrylate resin, which contains as the groups capable of bringing about the self-crosslinking acid amide derivative groups corresponding to the general struc- tural formula -CO-N(R1)-CH(R2)-OR3, wherein R1 = a hydrogen atom or a -CH(R2)-OR3 group, R2 = a hydrogen atom or a -COOR4 group, R3 = a hydrogen atom or a hydrocarbon radical of 1 to 10 carbon atoms, preferably the methyl, ethyl, (iso)propyl or (iso)butyl radical, R4 = an alkyl radical of 1 to 5 carbon atoms; (B) 5 to 50% by weight, preferably 7 to 20% by weight, of a melamine resin dispersed or dissolved in an aqueous medium (C) 0 to 40% by weight, preferably 5 to 20% by weight, of a urea resin dispersed or dissolved in an aqueous medium; (D) 5 to 30% by weight, preferably 6 to 15% by weight, of a polyol component; and (E) 0.01 to 5% by weight, preferably 0.1 to 1.5% by weight, of an amine component, (A) to (E) adding up to 100% by weight; the curing component (II) consists of a water-dilutable acid and the components (I) and (II) are mixed prior to application in a ratio of 0.05 to 3 parts by weight, pre- ferably 0.05 to 2 parts by weight, of the pure curing component (II) to 100 parts by weight of the paint com- ponent (I). The invention further relates to a process for producing two-component paints as well as to their use for coating finishing sheeting and continuous edging.
