Patent ID: 8883391

Claim:
A positive-type photosensitive resin composition which comprises: (a) a polymer having, as a main component, a structure represented by the following general formula (1) and/or a polymer having, as a main component, a structure represented by the following general formula (2), (b) a quinonediazide compound, (c) a silane coupling agent having a structure represented by the following general formula (3), (d) a silane coupling agent having an epoxy, or an oxetanyl group, and (e) a solvent, wherein the positive-type photosensitive resin composition comprises 100 to 4,000 parts by weight of (d) the silane coupling agent having an epoxy, or an oxetanyl group, and having an alkoxysilyl group based on 100 parts by weight of (c) the silane coupling agent having a structure represented by general formula (3); wherein in the above general formula (1), R 1 and R 2 each independently represent a bi- to octavalent organic group having two or more carbon atoms; R 3 and R 4 each independently represent hydrogen or a monovalent organic group having 1 to 20 carbon atoms; n represents a number in the range of 10 to 100,000, l and m each independently represent an integer of 0 to 2, and p and q each independently represent an integer of 0 to 4, where p+q>0; wherein in the above general formula (2), R 5 represents a tetra- to decavalent organic group and R 6 represents a bi- to octavalent organic group; R 7 and R 8 represent a phenolic hydroxyl group, a sulfonic acid group or a thiol group, and may each be a single group or a combination of different groups; t represents a number in the range of 3 to 100,000, and r and s represent an integer of 0 to 6; wherein in the above general formula (3), R 9 to R 11 each independently represent hydrogen or an alkyl group having 1 to 3 carbon atoms; and R 12 to R 14 each independently represent an alkyl group having 1 to 6 carbon atoms, an alkenyl group having 2 to 4 carbon atoms, a phenyl group, a substituted phenyl group or an alkoxyl group having 1 to 6 carbon atoms, and at least one of R 12 to R 14 is an alkoxyl group having 1 to 6 carbon atoms.
