Abstract
Provided is a curable silicone composition for a release agent which can release a release film from a silicone adhesive with low release force without reducing the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. A release film or laminate having the small release force of the silicone adhesive is also provided. The curable silicone composition comprises: (A) a mixture of two or more fluoroalkyl group-containing organopolysiloxanes having a fluoroalkyl group and at least two alkenyl groups per molecule, wherein the contents of the fluoroalkyl groups differ from each other, and the two or more fluoroalkyl group-containing organopolysiloxanes are a combination of those which are not completely compatibilized at 25° C. when mixed in the absence of a solvent; (B) an organopolysiloxane having at least three silicon-bonded hydrogen atoms per molecule; (C) an effective amount of a hydrosilylation reaction catalyst; and (D) an organic solvent.
