Abstract:
Waterborne base coat compositions and processes for preparing base coat/clear top coat multi-layer coatings are provided. In an embodiment, a waterborne base coat composition includes water, pigment(s) and resin solids consisting of about 60 to 100 wt. % of binder solids and 0 to about 40 wt. % of crosslinker solids, the binder solids consisting of about 1 to about 40 wt. % of a urethanized polyester/(meth)acryl copolymer hybrid binder having a hydroxyl number of about 30 to about 200 mg KOH/g and a carboxyl number of about 8 to 50 mg KOH/g, and about 60 to about 99 wt. % of one or more further binders, the sum of the respective wt. % in each case equaling 100 wt. %.
