Procedure for the realization of a two-layer coating suitable for this process aqueous lacquers.

摘要

The invention relates to a process for the manufacture of lacquer coatings TWO COATS, WHERE APPLICABLE lacquering BASIC AQUEOUS Pigmented BEING COATED COATING BASE THUS OCCURRED WITH A CLEAR LACQUER AND THIS LACADO BASICS AND COVERING PAINTED LIGHT ARE STATES JOINTLY. THE process of the invention is characterized in that CONTAINING AQUEOUS BASE LACQUER an emulsion polymer produced in the presence of a product (A) REACTION. The product (A) OF REACTION CAN BE OBTAINED BY GENERATION (I) A butadiene homopolymer or copolymer (II) at least one fatty acid and a drying oil or at least one drying oil or a mixture of at least one fatty acid and a drying oil and at least one DRYING OIL (III) maleic anhydride TO REACT IN rEACTION MASS (I): (II): (III) = 1.0: 0.1 to 0, 6: 0.1 to 0.6 after the addition of a solution aqueous base, the reaction product BECOMES an aqueous dispersion.
