PROBLEM TO BE SOLVED: To provide an organohydrogenpolysiloxane mixture which is useful as a crosslinking agent and an adhesion improver of an addition-reaction curable silicone composition, and a releasable cured-film forming silicone composition which can form a releasable cured-film excellent in adhesion to the surface of various base materials. SOLUTION: There are provided an organohydrogenpolysiloxane mixture which comprises a partially branched, straight-chain organohydrogen polysiloxane having two or more silicon-atom-bonding hydrogen atoms in the molecule, has a viscosity at 25 deg.C of 80-700 mPa.s, and has a dispersion degree (weight average molecular weight/number average molecular weight) of 2.0-10.0, and a releasable cured-film forming silicone composition composed primarily of (A) an organopolysiloxane having a viscosity at 25 deg.C of 40 mPa.s or more and having two or more alkenyl groups in the molecle, (B) the organohydrogenpolysiloxane mixture, and (C) an addition-reaction accelerating catalyst.
