Disclosed is a novel curing system which is not associated with decomposition or production of low molecular materials. The curing system employs an aqueous composition which comprises (a) a compound having in one molecule at least two carbonylcyclic urea groups represented by the following formula (1) ##STR1## [wherein n is an integer of 0 to 5, X which may be the same or different and represents oxygen atom, a sulfur atom or --NR.sub.1 -- in which R.sub.1 is a hydrogen atom, an alkyl, hydroxyalkyl or alkylene group having 1 to 5 carbon atoms.] and (b) a basic resin which has a functional group reactive with an isocyanate group and is water soluble or water dispersible by neutralizing. The present invention also provides an aqueous composition comprising a basic resin (c) which has a functional group reactive with an isocyanate group and has in one molecule at least two carbonylcyclic urea groups represented by the following formula (1) ##STR2## wherein n and X are the same as mentioned above, and which is water soluble or water dispersible by neutralizing.

摘要:
The invention concerns a process for the preparation of acyl isocyanates which consists of reacting oxalyl chloride with a salt selected from the group consisting of hydrohalides and sulphates of carboxamides and/or carbamates, unsubstituted on nitrogen, then heating the reaction mixture at a temperature between 30.degree. and 150.degree. C. The process is suitable for preparation of acyl isocyanates with excellent yields in easy to control operational conditions.
