Title:
RELEASE FILM FOR GREEN SHEET PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2014/155895
Kind Code:
A1
Abstract:
Provided is a release film for green sheet production that comprises a substrate and a release agent layer. The release agent layer is formed by applying a material for release agent layer formation that contains an active energy ray-curable compound (A) comprising at least one reactive functional group that is selected from the group consisting of a (meth)acryloyl group, an alkenyl group, and a maleimide group, a polyorganosiloxane (B), and a carbon nanomaterial (C) to a first surface and irradiating the coating layer that is thereby formed with active energy rays. The release film for green sheet production is characterized in that the arithmetic average roughness (Ra1) of the outer surface of the release agent layer is 8 nm or less and the maximum protrusion height (Rp1) of the outer surface of the release agent layer is 50 nm or less. The present invention makes it possible to provide a release film for green sheet production that prevents the occurrence of pinholes, localized variation in thickness, or the like in the surface of a green sheet and that makes it possible to produce a highly reliable green sheet.
