Abstract: A coating composition comprising a thermoplastic acrylic polymer in a solution wherein the polymeric solution, devoid of pigment, has a surface tension of less than 25.2 dynes per centimeter at room temperature is particularly useful as an automotive top coating. The coating compositions, when sprayed onto substrates, exhibit increased efficiency of paint deposited per unit of paint sprayed.
