摘要：
Process for the production of film forming synthetic resins for hair fixative compositions by reacting a methylolated 5,5-dialkylhydantoin containing 1-5 carbon atoms in each alkyl group at an elevated temperature in the presence of a bifunctional acid amide and/or amine. Hair fixative compositions containing 2-10% by weight of the resin product as the major or sole resin compound.
