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 provides a process for producing a variety of unsaturated carbamic acid derivatives from corresponding unsaturated carbamates by substitution reaction. The present invention provides a process for producing unsaturated carbamic acid derivatives, comprising reacting an unsaturated carbamate represented by ##STR1## wherein R represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms, R.sup.1 represents a residue of an alcohol from which an OH group is removed, with an alcohol, a primary or secondary amine or an oxime at a temperature of 80.degree. to 150.degree. C. to substitute the --OR.sup.1 group in the formula (A).

Production of unsaturated carbamic acid derivative

The present invention provides a manufacturing method for unsaturated carbamic acid esters by allowing an unsaturated amide compound to react with a metallic base in an inert solvent, followed by a reaction with a halogenated formic acid ester. The invention also provides a manufacturing method of unsaturated carbamic acid esters by allowing an urethane derivative to react with a metallic base in an inert solvent, followed by a reaction with an unsaturated acid halide.

Process for producing unsaturated carbamic acid esters

An aqueous dispersion coating composition comprising at least one kind of resin, wherein any one of said resin or resins has at least one functional group selected from an active hydrogen-containing group, a substituted acylamide group and a water dispersible or water-soluble group, and wherein the resin composition as a whole contains each of the above described kinds of functional groups.
