Abstract:
1. A resin comprising: at least one repeating unit (A) selected from repeating units represented by any one of the following general formulae (III) to (V); a repeating unit (B) represented by the following general formula (I); and a repeating unit (C) represented by the following general formula (VI): wherein each of R R each of X R each of R A represents an ionic structural site capable of decomposing upon irradiation with an actinic ray or radiation to generate an acid in a side chain of the resin, wherein the repeating unit represented by the formula (III) is a repeating unit represented by the following general formula (III-1) or (III-4): wherein in formulas (III-1) and (III-4) Ar R R R wherein in formula (I) each of R Ar each of n Ys independently represents a hydrogen atom or a group capable of leaving by the action of an acid, provided that at least one of Ys represents a group capable of leaving by the action of an acid; and n represents an integer of from 1 to 4, wherein Y in the general formula (I) is represented by the following general formula (II): wherein each of L M represents a divalent linking group obtained by combining an alkylene group with —O—; Q represents an alkyl group, a cycloalkyl group, an alicyclic group which may contain a hetero atom, an aromatic ring group which may contain a hetero atom, an amino group, an ammonium group, a mercapto group, a cyano group or an aldehyde group; the group represented by -M-Q is a group constituted of from 5 to 20 carbon atoms; and at least two of Q, M and L and further provided that the repeating unit represented by the general formula (I) is selected from the group consisting of the following repeating units:  and wherein in formula (VI) each of R Ar n represents an integer of from 1 to 4; wherein a content of a group capable of decomposing by the action of an acid is expressed by a number (B) of a repeating unit having a group capable of decomposing by the action of an acid in the resin and a number (S) of a repeating unit having an alkali-soluble group which is not protected by a group capable of leaving by the action of an acid (B/(B+S)), and the content is from 0.05 to 0.40.
