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.

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.
