Abstract
Hydrophobic materials deposited on the surface of a substrate having a primer release coating of a water-insoluble, water-swellable polymer can easily be removed from the substrate upon exposure of the water-swellable polymer to an aqueous liquid. For example, paint applied to the surface of a steel panel precoated with a lightly cross-linked polyacrylate can easily be removed upon the immersion of the panel in water.
