Patent ID: 8367190

Claim:
A composition for preparing a protecting film, comprising: a) organosiloxane polymer; b) photobase generator; and c) organic solvent, wherein the organosiloxane polymer a) is polymerized from a silane compound represented by the following Formula 1 or Formula 2: SiR 1 p R 2 4-p [Formula 1] wherein, R 1 is each independently hydrogen; fluorine; aryl; vinyl; allyl; linear or branched alkyl having 1 to 20 carbon atoms that is unsubstituted or substituted with fluorine, R 2 is each independently a hydrolyzable functional group including linear or branched alkoxy having 1 to 4 carbon atoms, acetoxy, or chlorine, p is an integer of 0 to 2, and R 3 q R 4 3-q Si-M-SiR 5 r R 6 3-r [Formula 2] wherein, R 3 and R 5 are each independently hydrogen; fluorine; aryl; vinyl; allyl; or linear or branched alkyl having 1 to 20 carbon atoms that is unsubstituted or substituted with fluorine, R 4 and R 6 are each independently a hydrolyzable functional group including linear or branched alkoxy having 1 to 4 carbon atoms, acetoxy, or chlorine, M is alkylene having 1 to 6 carbon atoms or arylene, q and r are each independently an integer of 0 to 2.
