Abstract
Impression materials based on cross-linked aziridino-polyester compounds which tend to adhere to the surface to be reproduced, are made nonadhesive by the addition of 1-15% by weight of oleic acid ethanolamide with respect to the aziridino-polyether component, and may thereafter be more easily and smoothly released from the object to be reproduced.
