Abstract
Binders water-dilutable upon neutralization with inorganic and/or organic acids comprising the reaction product of (A) resins having at least 2 1,2-epoxy groups per molecule and an epoxy equivalent of at least 160; and (B) a semiester of a dicarboxylic acid and an N-2-hydroxyalkyloxazolidine, and a process for the formation of the binders, is described. The binders have sufficient basic groups for neutralization with acids to provide water dilutability, as well as the functional groups required for crosslinking of the binders. The binders upon stoving provide films with good resistance characteristics and have reduced losses.
