Zusammenfassung:	Using at least one compound selected from the group consisting of a zirconyl compound and a zirconium alcoholate as an allophanation catalyst, an allophanate group-containing polyisocyanate composition is produced from a starting material of at least one isocyanate compound selected from the group consisting of an aliphatic diisocyanate, an alicyclic diisocyanate and an isocyanate pre-polymer obtained therefrom, and another starting material of a hydroxyl group-containing compound.
