Abstract
A positive photosensitive resin composition exhibiting excellent heat resistance is provided, which comprises an alkali-soluble resin component (A) and a photosensitizer (B), the component (A) including a resin component (A1) having a structural unit (a1) represented by general formula (a1) shown below: wherein R0 represents a hydrogen atom or a methyl group; R1 represents a single bond or an alkylene group of 1 to 5 carbon atoms; R2 represents an alkyl group of 1 to 5 carbon atoms; and a represents an integer of 1 to 5, and b represents 0 or an integer of 1 to 4, with the proviso that the sum of a and b is 5 or less, and when two or more R2 are present, R2 may be the same or different.
Claims8
A photosensitive resin composition comprising an alkali-soluble resin component (A) and a photosensitizer (B),
- said component (A) comprising a resin component (A1) having a structural unit (a1) represented by general formula (a1) shown below:
- wherein R0 represents a hydrogen atom or a methyl group;
- R1 represents a single bond or an alkylene group of 1 to 5 carbon atoms;
- R2 represents an alkyl group of 1 to 5 carbon atoms;
- and a represents an integer of 1 to 5, and b represents 0 or an integer of 1 to 4, with the proviso that the sum of a and b is 5 or less, and when two or more R2 are present, R2 may be the same or different,
- wherein the amount of the structural unit (a1) based on the combined total of all structural units constituting the resin component (A1) is 100 mol %, and the content of the component (A1) within the component (A) is 100 mol %,
- wherein said photosensitizer (B) is a guinonediazide group-containing compound.
