摘要:
The present invention relates to aminoacrylates which have a viscosity of 200 to 3000 mPa.s at 23.degree. C. and 100% solids, a content of olefinic double bonds (calculated as C=C, molecular weight=24) of 8 to 20% by weight and a nitrogen content of 0.4 to 2.0% by weight, and which are prepared by an addition reaction by reacting at a molar ratio of primary amino groups from component a) to olefinic double bonds from component b) of 0.05:1 to 0.25:1a) mono- or diamines having a molecular weight of 31 to 300 and having aliphatically bound amino groups withb) acrylic esters of polyhydric alcohols which have been prepared at a COOH/OH equivalent ratio of 0.8:1 to 1:1 fromb1) acrylic acid andb2) ether-alcohols which have 3 or 4 hydroxyl groups and a molecular weight of 136 to 1000, possess at least one ethylene oxide unit --CH.sub.2 --CH.sub.2 --O-- as part of the ether structure and do not contain propylene oxide units --CH.sub.2 --CH(CH.sub.3)--O--.The present invention also relates to a process for the preparation these aminoacrylates.
