INORGANIC FINE PARTICLE DISPERSION PASTE COMPOSITION, INORGANIC FINE PARTICLE DISPERSION SHEET, AND METHOD FOR PRODUCING INORGANIC FINE PARTICLE DISPERSION SHEET

摘要

PROBLEM TO BE SOLVED: To provide a methacrylic copolymer for a binder which does not thermal degrade easily, has excellent low-temperature decomposability and can provide a sheet having high mechanical strength when used in an inorganic fine particle-dispersion paste composition, and to provide an inorganic fine particle-dispersed paste composition and an inorganic fine particle dispersion sheet.SOLUTION: There is provided a methacrylic copolymer for a binder formed from three or more methacrylic monomers, which has a segment derived from n-butyl methacrylate, wherein the content of the segment derived from n-butyl methacrylate is 10 to 60 wt.% and the methacrylic copolymer has a glass transition temperature of 10 to 35°C and a weight average molecular weight of 100000 to 3000000.
