Abstract
It is an object of the present invention to provide a polyvinyl acetal resin composition capable of giving a ceramic green sheet which has sufficient flexibility and is hardly damaged even when being formed into a thin film and comprises a polyvinyl acetal resin composition containing a polyvinyl acetal resin A and a polyvinyl acetal resin B incompatible with the polyvinyl acetal resin A, which is formed by acetalizing a mixed polyvinyl alcohol containing two or more kinds of polyvinyl alcohols wherein a phase composed of the polyvinyl acetal resin A and a phase composed of the polyvinyl acetal resin B form a sea-island structure.
