R" represents a hydrogen atom, an alkyl group, a  lactone-containing cyclic group, a carbonate-containing  cyclic group, or a -SO$_{2}$-containing cyclic group. A" rep› resents an oxygen atom, a sulfur atom or an alkylene group  having 1 to 5 carbon atoms which may contain an oxygen  atom or a sulfur atom. p’ represents an integer of0 to 3, and  q’ represents 0 or 11  [0328]  In Formulae (ax3-r-2) and (ax3-r-3), A" has the  same definition as that for A" in Formulae (a2-r-2), (a2-r-3)  and (a2-r-5).  [0329]  Examples of the alkyl group, the alkoxy group, the  halogen atom, the halogenated alkyl group, -COOR",  ---OC(=O)R", and the hydroxyalkyl group as Ra’$^{31 }$include  the same groups as those described above in the explanation  ofRa’$^{21 }$in Formulae (a2-r-1) to (a2-r-7).  [0330]  Specific examples of the groups represented by  Formulae (ax3-r-1) to (ax3-r-3) are shown below.  [0325]  The "carbonate-containing cyclic group" indicates  a cyclic group having a ring (a carbonate ring) containing  -O----C(=O)-O- in the ring structure thereof. In a case  where the carbonate ring is counted as the first ring and the  group contains only the carbonate ring, the group is referred  to as a monocyclic group. Further, in a case where the group  has other ring structures, the group is referred to as a  polycyclic group regardless of the structures. The carbonate› containing cyclic group may be a monocyclic group or a  polycyclic group.  [0326]  The carbonate ring-containing cyclic group is not  particularly limited, and an optional group may be used.  Specific examples thereof include groups represented by  Formulae (ax3-r-1) to (ax3-r-3) shown below.
