Abstract

The present invention provides a releasable film forming composition comprising (1) an organopolysiloxane having hydroxyl groups at the ends of the molecular chain, (2) a finely divided silica, (3) a phenyl-containing organosilane or organopolysiloxane, (4) an organohydrogenpolysiloxane containing at least three SiH groups per molecule, (5) a metallic salt of an organic acid and (6) an organic solvent, and a process for preparing same, as well as a releasable film forming composition comprising (1) an organopolysiloxane containing at least two silicon atom-bonded alkenyl groups per molecule, (2) a finely divided silica, (3) a phenyl-containing organosilane or organopolysiloxane, (4) an organohydrogenpolysiloxane containing at least two SiH groups per molecule, (5) a platinic compound and (6) an organic solvent, and a process for preparing same. These compositions exhibit a superior printability and a stable releasability from adhesive materials and are less slippery.
