BINDER COMPOSITION FOR CERAMIC MOLDING AND CERAMIC GREEN SHEET USING THE SAME
PROBLEM TO BE SOLVED: To provide a binder composition for ceramic molding which is excellent in baking properties, shows high strength of a green sheet when used in a green sheet and is capable of reducing warp of a ceramic substrate produced in baking and a ceramic green sheet using it.SOLUTION: A binder composition for ceramic molding comprises a (meth)acrylic polymer A which contains a structural unit derived from a (meth)acrylic acid alkyl ester monomer and has a weight average molecular weight of 100,000 or higher and a glass transition temperature of 0°C or higher and a (meth)acrylic oligomer B of a weight average molecular weight of 1,000-30,000, and the glass transition temperature of the (meth)acrylic polymer A is higher than the glass transition temperature of the (meth)acrylic oligomer B.
