56  US 9,069,246 B2  55  -continued  R  ~  ~OH  0  OJ!?  0  0  In formulae (Alla) and (AIIb ), R$_{1}$c represents a hydrogen  atom, a methy I group, a trifluoromethy I group or a hydroxym› ethy l group.  R$_{2}$c to R$_{4}$c have the same meaning as R$_{2}$c to R$_{4}$ c in formula  (VIIa).  Specific examples of the repeating unit represented by  formula (Alla) or (AIIb) are illustrated below, but the present  invention is not limited thereto.  The resin (B) preferably contains a repeating unit having an  alicyclic hydrocarbon structure substituted with a polar  group. Thanks to this configuration, the adherence to sub› strate and the affinity for developer can be enhanced. The  polar group is preferably a hydroxyl group or a cyano group.  The hydroxyl group as the polar group forms an alcoholic  hydroxyl group.  The content of the lactone group-containing repeating unit  (in the case of containing a plurality of lactone group-con› taining repeating units, the sum total thereof) is preferably  from 3 to 70 mo!  %, more preferably from 5 to 60 mo! %,  based on all repeating units in the resin (B).  The resin (B) may contain a plurality of repeating units  each containing a lactone group. In this case, either one of (1)  using one repeating unit where Ab in formula (AI) is a single  bond and one repeating unit where Ab is -Ab$_{1 }$-CO$_{2}$-, or (2)  using, in combination, two repeating units where Ab in for› mula (AI) is -Ab$_{1}$-CO$_{2}$-, is preferred.  (Allb)  x:f(\J  ~CN  (Alla)  [Chem. 29]  The repeating unit having a group represented by formula  (VIIa) or (VIIb) includes a repeating unit where at least one of  R$_{13}$’ to R 16 ’ in formulae (II-AB!) and (II-AB2) has a group  represented by formula (VIIa) or (VIIb ), and a repeating unit  represented by the following formula (Alla) or (AIIb).  Examples of the former include a structure where Rs of  -COO Rs is a group represented by formula (VII a) or (VIIb).  The group represented by formula (VIIa) is preferably a  dihydroxy form or monohydroxy form, more preferably a  dihydroxy form.  In formula (VIIa), each of R$_{2}$c to R$_{4}$c independently rep› resents a hydrogen atom, a hydroxyl group or a cyano group,  provided that at least one ofR$_{2}$c to R$_{4}$c represents a hydroxyl  group or a cyano group. A structure where one or two mem› bers out ofR$_{2}$c to R$_{4}$ c are a hydroxyl group with the remain› ing being a hydrogen atom is preferred, and it is more pre› ferred that two members out of R$_{2}$c to R$_{4}$ c are a hydroxyl  group and the remaining one member is a hydrogen atom.  The alicyclic hydrocarbon structure substituted with a  polar group includes, for example, a structure represented by  the following formula (VIIa) or (VIIb):  [Chem. 28]  (Vila)  (Vllb)
