Abstract
Abstract A resin composition is described consisting essentially of from 0.5 to 100 parts by weight of a water-soluble polyamide and from 0.5 to 100 parts by weight of a vinyl alcohol-based polymer. The resin composition has excellent transparency and can be used, for example, to form light-sensitive resin compositions and adhesives.
