| 摘要 |
The invention relates to an aqueous paint formulation consisting of an aqueous base coat and an aqueous dispersion of an at least partially neutralised ethylene copolymer wax, which is selected from those ethylene copolymer waxes which contain the following as comonomers through polymerization: (A) 12 to 40 wt % of an ethylenically unsaturated carboxylic acid of formula (I), where R1 and R2 are hydrogen and/or C1-C10 alkyl; 60 to 88 wt % of ethylene, 0 to 10 wt % of a further comonomer, or 5 to 50 wt % of a comonomer of formula (II), where R1 and R2 are hydrogen and/or C1-C10 alkyl, R3 is hydrogen, C1-C10 alkyl and/or C3-C12 cycloalkyl, where two radicals R3 can be bonded to a ring, X is oxygen, sulphur and/or N-R4, R4 is C1-C10 alkyl or hydrogen, and A1 is a divalent group; 50 to 95 wt % of ethylene and zero to 20 wt % of a further comonomer, wherein the ethylene copolymer wax (A)(B)(C) and (A')(B')(C') have a molecular weight of 10,000 to 100,000 and 5,000 to 40,000 g/mol, respectively; and to the use thereof for coating plastics.
