Patent ID: 7029754

Claim:
A hiding layer-forming silicone composition comprising (A) 100 parts by weight of a linear diorganopolysiloxane comprising structural units of the following formula (1) and having an average degree of polymerization of at least 50, wherein R 1 is a substituted or unsubstituted alkyl or aryl group having 1 to 20 carbon atoms, R 2 is R 1 , alkenyl, alkoxy, alkoxyalkoxy, hydroxyl or epoxy group, each of R 1 and R 2 is identical or different, and O is shared between adjoining structural units to form a siloxane bond, said linear diorganopolysiloxane comprising 5 mol % or less of tri- and tetrafunctional structural units, (B) 10 to 200 parts by weight of an organopolysiloxane comprising structural units of the following formulae (2) and (3): (R 1 —) n (R 2 —) 3−n Si—O— (2) wherein R 1 and R 2 are methyl or phenyl, each of R 1 and R 2 is identical or different, n is an integer of 1 to 3, and O is shared between adjoining structural units to form a siloxane bond, said branched diorganopolysiloxane comprising 30 mol % or less of di- and trifunctional structural units, (C) 200 to 500 parts by weight of an inorganic powder opacifier, selected from the group consisting of aluminum, brass, oxidized brass, copper, and carbon black, per 100 parts by weight of components (A) and (B) combined, (D) an effective amount of a curing catalyst for causing components (A) and (B) to cure, and (E) an organic solvent.
