PROBLEM TO BE SOLVED: To provide a solventless silicone releasing agent composition of an addition reaction-type and giving a releasing silicone cured film having excellent coating, releasing and slipping properties, and to provide a release paper having a cured film of the composition on it. SOLUTION: The silicone releasing agent composition contains, as essential components, (A) an alkenyl-containing organopolysiloxane having a viscosity of 5-25 mPa.s at 25 deg.C, (B) an organopolysiloxane expressed by formula (1) (R<1> R2 SiO1/2 )2 (R<2> R2 SiO1/2 )a (R2 SiO)m (RSiO3/2 )a ...(1) (wherein, R is a monovalent hydrocarbon group containing no aliphatic unsaturated bond; R<1> and R<2> are each R, OH or an alkenyl; 1,000<=m<=10,000; a is 0 or 1; and the content of the alkenyl is <=0.1 mol% of the total of R, R<1> and R<2> ), (C) an organohydrogenpolysiloxane and (D) a platinum group metal catalyst. The composition has a viscosity of 100-500 mPa.s at 25 deg.C and containing no organic solvent.
