Silicone release agent composition and a release paper or film

Abstract

The present invention provides a silicone release agent composition comprising the components (A), (B), (C) and (D): 50 to 99.9 parts by mass of (A) linear or branched organopolysiloxane represented by the general formula (1) and having at least two alkenyl group-containing organic groups and at least one aryl group-containing organic group in one molecule and having no fluorine-containing organic group, wherein a percentage of the number of the alkenyl group-containing organic group is 0.005 to 5% and a percentage of the number of the aryl group-containing organic groups is 0.1 to 40%, each based on the total number of groups each bonded to a silicon atom; 50 to 0.1 part by mass of (B) linear or branched organopolysiloxane having at least one alkenyl group-containing organic group and at least one fluorine-containing organic group in one molecule, wherein a percentage of the number of the fluorine-containing organic group is 3% to 50%, based on the total number of groups each bonded to a silicon atom, provided that the total amount of components (A) and (B) is 100 parts by mass; (C) organohydrogenpolysiloxane having three or more hydrogen atoms each bonded to a silicon atom in one molecule and having no fluorine-containing organic group, in such an amount that a ratio of the number of the SiH group in component (C) to the total number of the alkenyl group in components (A) and (B) is from 0.5 to 15; and a catalytic amount of (D) platinum group metal catalyst, provided that the silicone release agent composition does not comprise (E) organohydrogenpolysiloxane having one or more hydrogen atoms each bonded to a silicon atom and having a fluorine-containing organic group.
