Abstract: Provided is a curable silicone composition for a release agent which can form a release film having a silicone adhesive with a low release force even when thin and which does not reduce the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. A release film and laminate are also provided. The curable silicone composition comprises: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing the following components (A1) and (A2) at a mass ratio of 1/99 to 45/55: (A1) a fluoro(poly)ether modified organopolysiloxane having at least two alkenyl groups per molecule along with a fluoro(poly)ether-containing organic group; (A2) a fluoroalkyl group-containing organopolysiloxane having at least two alkenyl groups per molecule along with a fluoroalkyl group having 1 to 12 carbon atoms; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation reaction catalyst; and (D) an organic solvent.

Abstract: Provided is a curable silicone composition for a release agent which can form a release film having a silicone adhesive with a low release force even when thin and which does not reduce the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. Also provided is a release film, laminate, and method of manufacture. The curable silicone composition comprises: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing the following components (A1) and (A2) at a mass ratio of 1/99 to 99/1; (A1) a fluoro(poly)ether modified organopolysiloxane having at least two alkenyl groups per molecule along with a fluoro(poly)ether-containing organic group; (A2) a fluoroalkyl group-containing organopolysiloxane having at least two alkenyl groups per molecule along with a fluoroalkyl group represented by C4F9—CH2CH2—; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation reaction catalyst; and (D) an organic solvent.

Abstract: Provided is a resin-linear organopolysiloxane block copolymer which has a high degree of freedom in formulation due to excellent compatibility with other materials, in addition to exhibiting excellent film forming properties and followability of a film, while the stickiness of a film is suppressed. The resin-linear organopolysiloxane block copolymer has: a resin structure (A1) block that has siloxane units represented by R1SiO3/2 (wherein R1 represents a monovalent organic group, a hydroxyl group, or an alkoxy group having 1 to 6 carbon atoms) and SiO4/2; and a linear structure (A2) block represented by (R2SiO2/2)n (wherein n represents a number of 5 or more while R represents an alkyl group, a fluoroalkyl group, or an aryl group) in each molecule. The resin structure (A1) and the linear structure (A2) are linked to each other by an Si—O—Si bond, and an Si atom bonded to the resin structure (A1) constitutes an RSiO3/2 unit.
