Abstract:
1. An actinic ray-sensitive or radiation-sensitive resin composition comprising: (P) a resin which contains (A) a repeating unit having an ionic structure moiety capable of producing an acid upon irradiation with an actinic ray or radiation, wherein a cation moiety of the ionic structure moiety has an acid-decomposable group or an alkali-decomposable group, provided that an anionic moiety of the ionic structure moiety is bonded to a main chain of the resin (P) via covalent bond, and the cationic moiety is free as a counter cation; wherein the repeating unit (A) is a repeating unit represented by any one of the following formulas (III) to (V): wherein in formulas (III) to (V), each of R R each of X R each of R A represents the ionic structure moiety which produces an acid upon irradiation with an actinic ray or radiation and in which the counter cation is a cation having an acid-decomposable group or an alkali-decomposable group, and the repeating unit (A) contains a repeating unit represented by formula (III), and an acid generated from the repeating unit represented by formula (III) has an acid anion represented by the following formula: wherein R Ar R R
