Abstract
This invention provides the use and preparation of certain 2,2'-diacetyl-bisacetoacetates and bis(beta-ketoesters). These compounds are useful in coating formulations as crosslinkers in conjunction with polyester, acrylic and/or other hydroxylated resins to provide coatings that cure at about 100.degree. and 175.degree. C. Certain combinations of these crosslinkers and resins cure at unusually low temperatures and provide films with good combinations of flexibility, hardness and adhesion.
