Description

technical field

[0001] The present invention relates to a flexible, adhesive to resin substrates under high humidity, heat resistance, pyrolysis, moisture resistance, toughness and low oxygen transmission rate, moderate adhesiveness, prepared as a solution Modified polyvinyl acetal resin with low viscosity and excellent temporal stability of viscosity, and adhesive composition, ink, coating composition, heat-developable photosensitive material, and slurry composition for ceramic green sheets using the same objects, and ceramic green sheets. Background technique

[0002] Conventionally, polyvinyl acetal resins such as polyvinyl butyral resins have excellent toughness, film-forming properties, dispersibility of inorganic and organic powders such as pigments, and adhesion to the coated surface, so they have been used in In various applications such as inks, paints, baking enamel, coatings for etching, cellulose coatings, dispersants, adhesives, ceramic green sheets, heat-devel...
