Abstract
The present invention relates to an aqueous coating material based on a water-soluble resin having the OH group for airbag base fabric. The water-soluble resin is a polyvinyl alcohol (PVAL). An aliphatic carboxylic acid or polyisocyanate which can cross-link with the OH group of the PVAL by heat treatment, and polyol as a plasticizer such as a liquid polyethylene glycol which does not volatilize in heat treatment are added. A water-insoluble coating film having excellent heat and moisture resistance (hot water resistance) and flexibility can be formed on one surface or both surfaces of the cloth.
