Mixture of I. nucleus-unsubstituted or m-substituted N.N-dialkanol arylamides and II. p-substituted arylamines obtained by reaction of I. with diisocyanates and/or dicarboxylic acids work as excellent accelerators in unsaturated polyester resin compositions which then show a favorable pot-life, high stability in storage and rapidly obtainable sandability. |
