  • Multilayered finish having good stain resistance
    Patent number: 4844952
    Abstract: A method of forming a multilayered finish on a substrate involves:I. applying a decorative finish to a substrate:II. applying a clear, aqueous based coating composition over the decorative finish of step I, said clear coating composition containing:(a) a waterborne polymer having calculated a glass transition temperature of at least about 40.degree. C. and having a one component working parameter of solubility, .delta. wp, in the range of about 9.0 to about 9.6 (cal./cm.sup.3).sup.1/2, with ##EQU1##whereinFi=the molar attraction constant of an individual functional group of the polymer expressed in cal..sup.1/2 cm.sup.3/2 /mole, andVi=the molar volume constant of an individual group of the polymer expressed in cubic cubic centimeters per mole; and(b) an amount of coalescing component sufficient to form a coalesced film, said clearcoating composition being essentially free of external crosslinking agents; andIII. allowing the coating composition to coalesce.
