US 9,612,535 B2  108  107  -continued  (B-33)  ~-0  0  ~  \  j  I  (OH)a  (B-34)  ~  ~\,l  ~I  (OH)a  (B-35)  (B-36)  (B-37)  (B-38)  The repeating unit represented by Formula (A) is prefer› ably the repeating unit represented by the following Formula  (Al) or (A2), and more preferably the repeating unit repre› sented by Formula (Al).  (Al)  OH  (A2)  R23  ~  ¢  OH  In Formula (A2), R$_{23 }$ has the same meaning as R$_{23 }$ in  Formula (A).  The resin (P) may contain two kinds or more of the  repeating units represented by Formula (A).  The resin (Ab) may include, in one embodiment, the  repeating unit (B) having the structure that decomposes to  generate an acid upon irradiation with electron beam or  extreme ultraviolet rays (Hereinafter, referred to "the acid  generating repeating unit (B)" or "the repeating unit (B)").  This structural moiety may be, for example, a structural  moiety which decomposes upon irradiation with an actinic  ray or radiation to generate an acid anion in the repeating  unit (B), and a structural moiety which releases an acid  anion to generate a cation structure in the repeating unit (B).  In addition, this structural moiety is preferably, for  example, an ionic structural moiety having a sulfonium salt  structure or an iodonium salt structure.  This structural moiety may be, for example, the same  structural moiety as the structural moiety represented by A  in Formulas (Bl), (B2) and (B3) to be described later.  The repeating unit (B) is, in one embodiment, preferably  at least one selected from the group consisting of the  repeating unit represented by the following Formulas (Bl),  (B2) and (B3). Among these, the repeating unit represented  by the following Formula (Bl) or (B3) is more preferred,  and the repeating unit represented by the following Formula  (Bl) is particularly preferred.
