Document Type and Number:
Japanese Patent JP6710760
Kind Code:
B2
Abstract:
The present invention relates to a pigmented aqueous basecoat material comprising a polyether-based reaction product which is preparable by reaction of (a) at least one cyclic carboxylic anhydride comprising a free carboxylic acid group and/or the halide of a carboxylic acid group with(b) at least one polyether of the general structural formula (I)in whichR is a C3 to C6 alkylene radical and n is selected accordingly such that the polyether (b) possesses a number-average molecular weight of 800 to 4000 g/mol, the components (a) and (b) being used in the reaction in a molar ratio of 0.7/2.3 to 1.6/1.7 and the resulting reaction product possessing an acid number of 10 to 50 mg KOH/g.
