The present invention is directed to a coating composition comprising a vinyl acrylic copolymer latex wherein said copolymer latex has a water contact angle of about 60 or higher on the dried latex film surface, wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr. The invention is also directed to the copolymer latex itself. Further, the invention is a method of improving a coating's ability to withstand a high humidity environment comprising adding a vinyl acrylic copolymer latex to the coating composition wherein said copolymer latex has a water contact angle of about 60 or higher on the dried latex film surface, and wherein said copolymer latex further has a specific water vapor permeability of about 0.5 mg/cm/mm/24 hr.
