Patent ID: 8211619

Claim:
A positive photosensitive composition comprising: (A) a curable silicone resin having a silanol group, the resin being obtained by a reaction between a cyclic siloxane compound represented by the following general formula (1): (wherein R 1 , R 4 and R 7 are C 1 to C 10 alkyl groups, cycloalkyl groups or aryl groups that may be the same or differrent; R 2 , R 5 and R 8 are C 1 to C 10 alkylene groups that may be the same or different and be substituted by a hydrocarbon group; R 3 and R 6 are C 1 to C 4 alkyl groups that may be the same or different; e is a number of 0 or 1 to 4 and g is a number of 1 to 3, provided that e+g does not exceed 5; h is a number of 0 or 1 to 4 and i is a number of 1 to 3, provided that h+i does not exceed 5; R 9 is a C 1 to C 6 alkyl group or cycloalkyl group that may be the same or different; R 10 is a C 1 to C 3 alkyl group; j is a number of 1 to 3; and m, n and q are numbers satisfying m:n:q=1:0 to 2:0.5 to 3 as well as m+n+q=3 to 6) and an arylalkoxysilane compound represented by the following general formula (2): (wherein R 11 is a C 1 to C 6 alkyl group or cycloalkyl group that may be the same or different; R 12 is a C 1 to C 3 alkyl group; R 13 is a C 1 to C 4 alkyl group that may be the same or different; r is a number of 1 to 3; and u is a number of 0 or 1 to 5); (B) diazonaphthoquinones; and (C) a solvent.
