Top coating composition

The present invention provides a method for producing N-acyl carbamate in high yield. The method of the present invention comprises the step of reacting an unsaturated acid halide with a carbamate in the presence of a hindered amine. Another method of the present invention comprises the step of reacting a N,N-diacyl carbamate with an active hydrogen compound.

Method for producing N-acyl carbamate

The present invention relates to a triazole compound represented by the formula (1): ##STR1## wherein R.sup.1 represents a lower alkyl group which may have a substituent; R.sup.2 and R.sup.3 represent respectively hydrogen, an aryl group, a benzoyl group, a tosyl group, a lower alkoxy carbonyl group, or an aryl sulfonyl group, each of which except for hydrogen may have a substituent; provided that when R.sup.2 is hydrogen, the triazole compound is represented by the formula (2): ##STR2## wherein R.sup.1 and R.sup.3 have the same as defined above.

Hydrazide intermediates

The present invention relates to compounds containing an oxamic acid group, which show high reactivity and have stability for water and are used as paints, adhesives, and plastic materials etc. in the form of a reaction material or a resin. Since into these compounds an oxamic acid group is introduced in a part of the molecule and the oxamic acid group is an ionic functional group, the compounds show superior solubility and dispersing character in water and also, since the oxamic acid group is a group of a disappearing type with heating, the compounds do not remain, after hardening, in the hardened product. Accordingly, the hardened products obtained from these compounds are superior in water-resistant and anticorrosion properties and in durability.
