Patent ID: 7108951

Claim:
A photosensitive resin composition comprising: (A) a resin containing (A1) a repeating unit having at least two groups represented by the following general formula (Z), wherein the resin is alkali-soluble, or the resin is decomposed by the action of an acid to increase its solubility in an alkaline aqueous solution; and (B) a compound capable of generating an acid by the action with one of an actinic ray and a radiation: wherein R 50 to R 55 each independently represents a hydrogen atom, a fluorine atom, or an optionally substituted alkyl group, provided that at least one of R 50 to R 55 represents a fluorine atom or an alkyl group in which at least one hydrogen atom is substituted with a fluorine atom; and R represents an organic group, wherein the repeating unit (A1) is represented by the following general formula (1), (2) or (3): wherein Q 1 represents an alicyclic hydrocarbon group; L 1 represents a single bond or a connecting group; X 1 represents a connecting group having a valence of(m+1); R b represents a hydrogen atom, an optionally substituted organic group, or a halogen atom; 1 represents an integer of from 0 to 3; m represents an integer of 2 or more; and Z represents the group represented by the general formula (Z): wherein, R x1 and R y1 each independently represents a hydrogen atom, a halogen atom, a cyano group, or an optionally substituted alkyl group; L 2 represents a single bond or a connecting group; X 2 represents a connecting group having a valence of (n+1); n represents an integer of 2 or more; and Z represents the group represented by the general formula (Z): wherein, Q 1 , Rb and 1 have the same meaning as shown in the general formula (1); L 3 represents a connecting group; p represents an integer of 2 or more; and Z represents the group represented by the general formula (Z).
