Patent ID: 8507171

Claim:
A photosensitive composition, comprising: a compound (A) represented by the following general formula (I); a siloxane polymer (B), which has alkali solubility and is synthesized by hydrolytic condensation of materials including two or more kinds of alkoxysilane compounds having different numbers of alkoxyl groups; a 1,2-quinone diazide compound (C); and a solvent (D) for dissolving the above-mentioned (A) to (C): wherein the alkoxysilane compounds include di-, tri- and tetra-functional alkoxysilane compounds, where: R's independently represent hydrogen, an alkyl group having 1 to 45 carbon atoms, a cycloalkyl group having 4 to 8 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms; X's independently represent hydrogen, —Si(CH 3 ) 2 H, —Si(CH 3 ) 3 , —Si(CH 3 ) 2 (CH 2 ) 3 —OOCC(CH 3 )═CH 2 , —Si(CH 3 ) 2 (CH 2 ) 3 COOH, or a group represented by the following formula (II); in each of the alkyl group having 1 to 45 carbon atoms represented by R and the cycloalkyl group having 4 to 8 carbon atoms represented by R, any hydrogen may be replaced by fluorine, and any —CH 2 — may be replaced by —O— or a cycloalkylene group having 5 to 18 carbon atoms so long as the —CH 2 — is unadjacent to another —CH 2 —; and in a benzene ring of the substituted aryl group represented by R, any hydrogen bonded to the benzene ring may be independently replaced by an alkyl group having 1 to 10 carbon atoms or a halogen.
