ABSTRACT:
A water-dilutable lacquer binder comprising a mixture of A. 20 to 94% by weight of a copolymer consisting of copolymerized units of (a) 30 to 65% by weight of an aromatic vinyl or isopropenyl compound having 8 to 14 carbon atoms or of a methacrylic acid alkyl ester having 1 to 4 carbon atoms in the alcohol component, or any mixture thereof; (b) 10 to 30% by weight of at least one acrylic acid alkyl ester having 1 to 8 carbon atoms in the alcohol component; (c) 1 to 20% by weight of maleic acid, fumaric acid, itaconic acid or their semi-esters having 1 to 8 carbon atoms in the alcohol component, (meth)acrylic acid or any mixture of the aforesaid monomers; (d) 5 to 20% by weight of at least one hydroxyalkyl ester of (meth) acrylic acid having 2 to 4 carbon atoms in the alkyl group or glycidyl (meth)acrylate or any mixture of the aforesaid monomers; and (e) 10 to 30% by weight of N-methylol (meth)acrylic acid amide or N-methoxymethyl(meth)acrylic acid amide or any mixture thereof; B. 1 to 40% by weight of a saturated lactam, and C. 5 to 40% by weight of an aminoplast resin; wherein 30 to 100% of the number of carboxyl groups of component A. (c) incorporated in the copolymer have been neutralized by ammonia or monoamines or polyamines.
