CURING AGENT FOR ANIONICALLY CURABLE COMPOUNDS, CURABLE COMPOSITION, CURED PRODUCT, NOVEL IMIDAZOLE-BASED COMPOUND AND USE OF SAME

摘要

The present invention provides: a curing agent for anionically curable compounds, which is composed of an imidazole-based compound wherein the 1-position of the imidazole skeleton is protected with a protecting group (A) that can be eliminated at a temperature of 50°C or more; a curable composition which contains the curing agent and an anionically curable compound; a cured product which is obtained by curing the composition; the above-mentioned novel imidazole-based compound; and use of the imidazole-based compound. The present invention provides a novel imidazole-based curing agent which is easily handled and has excellent storage stability and good curability even in cases where the curing agent is used as a one-pack type curing agent. This imidazole-based compound is exemplified by an imidazole-based compound represented by general formula (1). In formula (1), A represents a protecting group that can be eliminated at a temperature of 50°C or more; and each of R1-R3 independently represents a hydrogen atom, an alkyl group having 1-15 carbon atoms or a phenyl group.
