POLYVINYL ACETAL RESIN, COMPOSITION FOR CERAMIC GREEN SHEET, CERAMIC GREEN SHEET AND LAMINATED CERAMIC CAPACITOR

摘要

To provide a polyvinyl acetal resin from which a composition that exhibits high viscosity even with a small addition amount and has high coating property without using an excessive solvent can be produced and a ceramic green sheet having excellent mechanical strength even when being formed into a thin layer can be produced; and to provide a composition for a ceramic green sheet, a ceramic green sheet and a laminated ceramic capacitor using the polyvinyl acetal resin in the manufacture of a laminated electronic component such as a laminated ceramic capacitor.SOLUTION: A polyvinyl acetal resin has an average degree of polymerization of more than 4,500 and 10,000 or less, and has an acetal group content of 45-80 mol%, a hydroxyl group amount of 18-50 mol%, and an acetyl group content of 0.5-20 mol%.SELECTED DRAWING: None
