Abstract
Emulsion copolymers having a core-shell structure with alkyl alkanoate, alkylene, alkyl acrylate and vinyl silane in the core and vinyl alkanoate in the shell are usable in pigmented surface coating compositions. These compositions have desired water permeability tensile strength and elongation properties at low temperatures. The compositions provide bridging for cracks present or developing in the surface.
