Abstract
A method of forming a multilayered finish on a substrate involves: PA0 I. applying a decorative finish to a substrate: PA0 II. applying a clear, aqueous based coating composition over the decorative finish of step I, said clear coating composition containing: PA1 (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## wherein PA2 Fi=the molar attraction constant of an individual functional group of the polymer expressed in cal..sup.1/2 cm.sup.3/2 /mole, and PA2 Vi=the molar volume constant of an individual group of the polymer expressed in cubic cubic centimeters per mole; and PA1 (b) an amount of coalescing component sufficient to form a coalesced film, said clearcoating composition being essentially free of external crosslinking agents; and PA0 III. allowing the coating composition to coalesce.
