PROBLEM TO BE SOLVED: To provide a coating material for an airbag base fabric comprising a water-soluble resin as a base material, from which a water-insoluble coating film having excellent heat and moisture resistance (hot water resistance) as well as flexibility can be formed on surface or both surfaces of the fabric.SOLUTION: An aqueous coating material for an airbag base fabric is provided, which essentially comprises polyvinyl alcohol (PVA). A blocked polyisocyanate component (B-NCO) as a crosslinking improver and a liquid polyol as a plasticizer are added to the coating material. The B-NCO is composed of a medium molecular weight form that is a polyether-modified prepolymer, or essentially comprises the medium molecular weight form, in which a small amount of a low molecular weight form is used together.

    【課題】耐熱湿性(耐熱水性)に優れるとともに柔軟性を有する水不溶性の被膜(塗膜)を布帛の片面又は両面に形成可能な水溶性樹脂をベースとするエアバッグ基布用塗料を提供すること。【解決手段】ポリビニルアルコール(PVA)をベースとするエアバッグ基布用の水性塗料。架橋改質剤としてブロックドポリイソシアナート成分(B−NCO)、及び、可塑性付与剤として液状ポリオールが添加されている。B−NCOが、ポリエーテル変性のプレポリマーである中分子量型からなる又は該中分子量型を主体とし少量の低分子量型と併用する。【選択図】図6
