Title
(EN) RELEASE FILM FOR CERAMIC GREEN SHEET PRODUCTION
(FR) FILM ANTI-ADHÉSIF POUR LA PRODUCTION DE FEUILLES CÉRAMIQUES NON CUITES
(JA) セラミックグリーンシート製造用離型フィルム
Abstract
(EN)
[Problem] To provide a release film for ceramic green sheet formation, wherein the release film has excellent light peeling properties and damage such as cracks is unlikely to occur in a half-cut test for ultra-thin ceramic green sheets formed therewith. [Solution] A release film for ceramic green sheet production in which a release layer is laminated onto at least one surface of a polyester film either directly or with another layer therebetween, the release layer being formed by curing a coating that includes at least an energy ray-curable compound (I), a polyester resin or polyester urethane resin (II), and a release component (III), and the hydroxyl value of the energy ray-curable compound (I) being no more than 45 mg KOH/g.

La présente invention concerne un film anti-adhésif pour la production de feuilles céramiques non cuites ayant d'excellentes propriétés de pelage et peu susceptible de développer des endommagements tels que des fissures pendant un essai de demi-coupe pour des feuilles de céramique ultra-minces non cuites à mouler. Plus particulièrement, l'invention concerne un film anti-adhésif ayant une couche anti-adhésive stratifiée, directement ou par l'intermédiaire d'une autre couche, sur au moins une surface d'un film de polyester. La couche anti-adhésive comprend un revêtement durci comprenant au moins un composé durcissable par rayonnement d'énergie (I), une résine de polyester ou une résine de polyester-uréthane (II), et un constituant anti-adhésif (III). La valeur hydroxyle du composé durcissable par rayonnement d'énergie (I) n'est pas supérieure à 45 mg KOH/g.
