Curable silicone composition, release coating agent comprising said composition, release film obtained using said release coating agent, and layered product including said release film

A curable silicone composition, comprising:

• (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 wherein 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 capable of compatibilizing the entire composition by uniformly compatibilizing the mixture of two or more fluoroalkyl group-containing organopolysiloxanes serving as component (A);
• wherein component (A) is a mixture of:
• (A1) one or more linear or branched organopolysiloxanes comprising fluoroalkyl group-containing organodisiloxane units, wherein the fluoroalkyl group is a 3,3,4,4,5,5,6,6,6-nonafluorohexyl group, and wherein the units are 39 mole % or more of the total organosiloxane units;
• and
• (A2) one or more linear or branched organopolysiloxanes comprising fluoroalkyl group-containing organodisiloxane units, wherein the fluoroalkyl group is a 3,3,4,4,5,5,6,6,6-nonafluorohexyl group, and wherein the units are 36 mole % or less of the total organosiloxane units.
