Abstract
An aqueous coating composition comprising a mixture of 90 to 99 wt. % of a filmforming binder composition comprising an alkali non-swellable core-shell addition polymer dispersion (I), and 1-10 wt. % of a rheology modifying addition polymer dispersion (II). It is required that the total amount of (meth)acrylic acid in 100 parts of the total addition polymer (I) is less than 1.75 wt. %. The aqueous coating composition of the present invention can be advantageously used as a base coat in a base coat/clear coat system. This use shows a decrease in strike-in effect compared to previous known base coat/clear coat systems.
