It is an object of the present invention to provide anmodified polyvinyl acetal resin, which is superior innflexibility, an adhesive property to a resin substratenunder high humidities, heat resistance, a thermalndecomposition property, humidity resistance and toughnessnand has low oxygen permeability and an adequate adhesivenproperty and is low in viscosity and high in secularnstability of viscosity in forming a solution thereof, andnan adhesive composition, an ink, a coating materialncomposition, a thermal developing photosensitive material,na slurry composition for a ceramic green sheet, and anceramic green sheet, which use the modified polyvinylnacetal resin. n The present invention is a modified polyvinyl acetalnresin, which is obtainable by acetalizing a modifiednpolyvinyl alcohol having ethylene in a random basis as anconstituent unit of a main chain and an ethylene contentnof 1 to 20 mole % and a saponification degree of 80nmole % or more and, has ethylene in a random basis as anconstituent unit of a main chain. |
