Beschreibung
Zusammenfassung:	To provide a blocked isocyanate composition which is less prone to viscosity change and coloration over time.SOLUTION: The present invention provides a production method for a blocked isocyanate composition, including a step of mixing and reacting a polyisocyanate and an oxime-based blocking agent, in which the ratio of the amount of the oxime-based blocking agent mixed to the amount of the polyisocyanate mixed is 0.91 to 0.99 in terms of an equivalent ratio.SELECTED DRAWING: None 【課題】経時的な粘度変化及び着色を起こし難いブロックイソシアネート組成物を提供すること。【解決手段】ブロックイソシアネート組成物の製造方法であって、ポリイソシアネートとオキシム系ブロック剤とを混合して反応させる工程を含み、ポリイソシアネートの混合量に対するオキシム系ブロック剤の混合量の比が、当量比で、０．９１～０．９９である、ブロックイソシアネート組成物の製造方法。【選択図】なし
