More Information
Summary:A method for producing a blocked isocyanate compound, the method comprising: a reaction step in which a primary amine compound, a carbonic acid derivative, and a blocking agent are reacted by heat treatment in the presence of one or more compounds selected from the group consisting of secondary amine compounds represented by general formula (I) and tertiary amine compounds represented by general formula (II); the blocked isocyanate compound is obtained. A method for producing an isocyanate compound, the method comprising: a reaction step for decomposing a blocked isocyanate compound into a blocking agent and an isocyanate compound by heat treatment in the presence of one or more compounds selected from the group consisting of a secondary amine compound represented by general formula (I) and a tertiary amine compound represented by general formula (II); the isocyanate compound is obtained.
