Title:
セラミックグリーンシート製造用離型フィルム
Document Type and Number:
Japanese Patent JP6813124
Kind Code:
B2
Abstract:
[Problem] To provide a mold release film for ceramic green sheet production, which is suppressed in deterioration of the surface roughness of a mold release layer due to aggregation during drying, thereby having high smoothness, and which has excellent releasability by adjusting the amount of a silicone component in the surface of the mold release layer. [Solution] A mold release film for ceramic green sheet production, which uses a polyester film as a base material, and which is configured such that: the base material has a surface layer A on at least one surface, said surface layer A substantially containing no particles; and a mold release layer is superposed on the surface of the surface layer A on at least one surface directly or with another layer being interposed therebetween. The mold release layer is obtained by curing a composition that contains a binder component and a silicone-based mold release agent; the Si element ratio in the mold release layer surface is from 2.0 at% to 10.0 at% (inclusive); and the mold release layer surface has a maximum profile peak height (P) of 50 nm or less and an area average roughness (Sa) of 1.5 nm or less.
