Abstract: A compound having thioacetal skeleton, a precursor thereof, a cured product thereof, and a composition for their production are provided for the thermally dissociatable material based on the inventors' finding that a thioacetal group is thermally dissociatable. The use of the thermally dissociatable material of the invention enables softening or liquefaction at any desired timing through thermal dissociation at a temperature below the thermal decomposition temperature of the cured product. It is thus possible to disassemble the structure to which the thermally dissociatable material had been attached in a short time. The thermally dissociatable material is useful as a highly disposable plastic material and is adapted for use as a sealant, coating composition or adhesive. Such material may be used, for example, as a curing agent for urethane curable composition or epoxy curable composition, or as a self-curable material.
