To provide a blocked polyisocyanate composition that offers superior storage stability when stored at high temperatures or low temperature, exhibits superior storage stability when made into a resin composition containing a polyhydric hydroxy compound, and demonstrates superior curability at low temperatures.SOLUTION: A blocked polyisocyanate composition contains blocked polyisocyanate. The blocked polyisocyanate is derived from polyisocyanate, and a blocker containing malonate diester. The malonate diester includes primary, secondary and tertiary alkyl groups.SELECTED DRAWING: None 【課題】高温保存または低温保存した場合の保存安定性が良好であり、多価ヒドロキシ化合物を含む樹脂組成物とした場合に貯蔵安定性に優れ、さらに低温での硬化性に優れるブロックポリイソシアネート組成物の提供。【解決手段】ブロックポリイソシアネートを含むブロックポリイソシアネート組成物であって、前記ブロックポリイソシアネートは、ポリイソシアネートと、マロン酸ジエステルを含むブロック剤と、から誘導され、前記マロン酸ジエステルが、１級、２級及び３級のアルキル基を有するマロン酸ジエステルである、ブロックポリイソシアネート組成物。【選択図】なし
