POLYVINYL ACETAL RESIN FOR CERAMIC GREEN SHEETS, PROCESS FOR PRODUCTION THEREOF, SLURRY COMPOSITION, CERAMIC GREEN SHEETS, AND LAMINTED CERAMIC CAPACITOR

摘要

Provided is a polyvinyl acetal resin which ensures excellent applicability in forming a ceramic green sheet and enables the formation of a ceramic green sheet having sufficient mechanical strengths and which is only slightly dissolved in an organic solvent contained in an electroconductive paste. A polyvinyl acetal resin characterized by: a degree of polymerization of 3000 to 5000; a vinyl ester unit content of 4 to 23mol%; a degree of acetalization of 60 to 80mol%; and a solution viscosity of less than 300mPa·s as determined at a solution temperature of 20°C with a Brookfield viscometer by using a 5 mass% solution prepared by dissolving the resin in a 1:1 ethanol/toluene mixed solvent.
