Document Type and Number:
Japanese Patent JP6441388
Kind Code:
B2
Abstract:
The present invention relates to a pigmented aqueous base paint, containing a polyether-based reaction product, which can be produced by reacting (a) at least one compound of formula (I), X1 - Y - X2 (I), wherein X1 and X2 stand independently of each other for a functional group reactive with hydroxyl groups and Y is a divalent aliphatic or araliphatic, carboxy-functional organic group having a number-average molecular weight of 100 to 1000 g/mol, with (b) at least one polyether of general structural formula (II), wherein R is a C3 to C6 alkylene group and n is selected accordingly in such a way that the polyether (b) has a number-average molecular weight of 200 to 4000 g/mol, wherein components (a) and (b) are used in a molar ratio of 0.7/2.3 to 1.6/1.7 in the reaction and the resulting reaction product has a number-average molecular weight of 500 to 15000 g/mol and an acid number of 10 to 120 mg KOH/g.
