Abstract
Provided are novel blocked polyisocyanurates to be suitably used as an adhesiveness providing agent, coating material, sealant and crosslinking agent for polymers containing active hydrogens. Also provided are polyvinyl chloride plastisol compositions comprising a polyvinyl chloride resin, the above blocked polyisocyanurate as an adhesiveness providing agent, plasticizer and a specific agent for accelerating dissociation of the blocked polyisocyanurate. These compositions have excellent properties such as high adhesiveness even cured at low temperatures and resistance to yellowing, and are suitably used particularly as sealants for car body.
