A release film for pressure-sensitive silicone adhesives which comprises: any of various bases; a primer layer (first layer) disposed on at least one surface of the base, the primer layer having a specific thickness and comprising as a main component an organosilicon compound having a plurality of silanol groups in the molecule; and a release layer (second layer) disposed on the outer surface of the primer layer, the release layer having a specific thickness and comprising as a main component a cured object obtained from a hydrolyzable fluorinated compound. A release coating film having excellent releasing properties can be stably and easily imparted to various bases, and the primer layer and the release layer can be formed even by room-temperature (25° C.) application.
A release film adapted for silicone pressure-sensitive adhesive, comprising a substrate, a primer layer disposed on at least one surface of the substrate as a first layer, and a release layer disposed on the outer surface of the primer layer as a second layer,
A layered structure comprising a release film adapted for silicone pressure-sensitive adhesive which comprises a substrate, a primer layer disposed on at least one surface of the substrate as a first layer, and a release layer disposed on the outer surface of the primer layer as a silicone second layer, and a pressure-sensitive adhesive disposed on the release layer of the release film,
