COATING MATERIAL FOR THICK GREEN SHEET, PROCESS FOR PRODUCING THE SAME, AND PROCESS FOR PRODUCING ELECTRONIC COMPONENT WITH THE COATING MATERIAL

摘要

A coating material for thick green sheet that can realize relatively thick coating and that with respect to a sheet resulting from the coating, excels in cutting property (strength capable of cutting), also excelling in air permeability and handling easiness, which coating material enables formation of a sheet of high bonding strength; a process for producing the coating material for thick green sheet; a process for producing a thick green sheet; a thick green sheet; and a process for producing an electronic component. There is provided a coating material for thick green sheet comprising a ceramic powder, a binder resin composed mainly of a butyral resin, and a solvent, wherein the solvent contains a good solvent capable of dissolving the binder resin to a high degree and a poor solvent whose capability of dissolving the binder resin is lower than that of the good solvent. The poor solvent is contained in a ratio ranging from 30 to 60 mass% based on the whole solvent. The good solvent is an alcohol, while the poor solvent is toluene, xylene, mineral spirit, benzyl acetate, solvent naphtha, etc.
