摘要： 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 present invention relates to polymerizable cyclic urea derivatives which can be thermally split to give rise to an isocyanate group; and to a polymer having cyclic urea pendant groups, which can be cured by heating without any additional curing agent such as an isocyanate blocked with a volatile lower molecular weight material, so that volatile material is not released in a thermal curing process.
