Abstract
Novel thermosetting resinous compositions are disclosed. The compositions comprise the reaction product of a polymeric polyol having a cured glass transition temperature less than 20.degree. C. with a substantial stoichiometric excess of an aminoplast curative. The cured compositions are hard with good durability and surprising flexibility for such high aminoplast loadings. These compositions are particularly useful as coatings for resilient and rubbery substrates such as foam rubber, polyurethane foam and vinyl foam and on soft metal surfaces such as mild steel and aluminum.
