A plastisol composition comprising a vinyl chloride polymer, a plasticizer and an adhesion-imparting agent, characterized in that the adhesion-imparting agent is a diisocyanate polymer blocked with an oxybenzoic acid ester or with an alkylphenol and having an average molecular weight within a range of from 1,000 to 10,000. Also disclosed is a blocked polyisocyanurate having the formula:
wherein each of X, Y and Z which may be the same or different, is a residue of a diisocyanate compound devoid of the isocyanate groups, each of R¹, R² and R³ which may be the same or different, is a group selected from the group consisting of C₁-C₂₀ alkyl, alkoxyalkyl, aryl, alkaryl and aralkyl, and n is an integer of from 1 to 10.
