Abstract: 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.

Abstract: Cathodic electrodeposition paints are rendered hardly susceptible to oil droplet-induced craters by incorporating an amine-modified acrylic copolymer of t-butyl (meth)acrylate with a hydroxyl group-containing monomer and an oxirane ring-containing monomer in the form of an aqueous emulsion. The amine-modified acrylic copolymer may be an adduct with a half blocked organic diisocyanate. The paint gives a cured film substantially free from oil droplet-induced craters and having a good adhesion to an overcoating and a good surface smoothness.

Abstract: A cathodic electrodeposition paint containing as a binder resin an amine-epoxy resin adduct and a blocked polyisocyanate crosslinker is disclosed. The binder resin and the crosslinker are emulsified in an aqueous medium containing a neutralizing agent with the aid of amine adduct of a monoepoxide compound having a hydrophobic group or block. Not only the amine-monoepoxide adduct functions as a surfactant but also it is deposited electrically and then cured with the crosslinker integrally with the binder resin.
