Abstract:
To provide a release film for producing a ceramic green sheet capable of molding a ceramic green sheet having less defects even in the case of an ultra-thin layer product having a thickness of 1 μm or less by providing a release layer which has excellent solvent resistance, small curing shrinkage and low peeling strength and is uniform while maintaining high smoothness of a release layer surface of a release film.SOLUTION: There is provided a release film for producing a ceramic green sheet which is obtained by providing a release layer on at least one surface of a polyester film, wherein the release layer is obtained by curing a composition comprising a radically curable substance (a) having one or more radical curable functional groups selected from a (meth) acryloyl group and an alkenyl group, a thiol group-containing compound (b), a releasing agent (c) and a radical initiator (d) and the curl amount measured by heat-treating the release film for one minute at 90°C under no tension is 2.0 mm or less.SELECTED DRAWING: None
