Abstract
A coating composition, useful for finishing automobiles and trucks, in which the film forming binder contains, as reactive binder components, a mixture of a first polymer having at least two reactive anhydride groups and a second polymer or oligomer having at least two reactive epoxy groups, characterized by the second polymer being structured so that the epoxy groups are skewed to have a majority thereof at one end of the polymer.
