<p>HOE 84/F 129 of the disclosure: Process for the preparation of acylurethanes by reacting a urethane with compounds containing hydroxyl groups, which comprises reacting a hydroxy compound A) with a urethane B) in the form of an imide of the formula (I) to give an acylurethane containing at least one grouping of the formula -CO-R-CO-NH-COOR1 (II). In these formulae, R denotes the hydrocarbon radical of an optionally .alpha.,.beta.ethylenically unsaturated, aliphatic, cycloaliphatic or aromatic dicarboxylic acid or endomethylene derivatives thereof, and R1 denotes alkyl, alkoxy, alkoxyalkyl, cycloalkyl or benzyl. These acylurethanes are suitable for use as self-crosslinking curing agents or as curing agents for polyhydroxy compounds for the production of shaped articles and/or coatings.</p> |
