Jan. 13, 2011  48  US 2011/0008728 Al  -continued  (blc-0-214)  [Chemical Formula 58]  -continued  (b 1 c-0-251)  (blc-0-221)  (blc-0-222)  (b 1c-0-252)  (blc-0-253)  (blc-0-223)  (blc-0-231)  (blc-0-232)  (blc-0-241)  (blc-0-233)  (blc-0-242)  (blc-0-243)  [0441]  In general formula (blc-0-3), R$^{71 }$represents a single  bond or a divalent linking group.  [0442]  Examples of the divalent linking group for R 71  include an alkylene group and a group containing a hetero  atom (hereafter, referred to as "hetero atom-containing link› ing group").  [0443]  The alkylene group is preferably a linear or  branched alkylene group, more preferably an alkylene group  of 1 to 5 carbon atoms, and still more preferably an alkylene  group ofl to 3 carbon atoms (a methylene group, an ethylene  group or a propylene group).  [0444]  The "hetero atom" within the hetero atom-contain› ing linking group is an atom other than carbon and hydrogen,  and examples thereof include an oxygen atom, a sulfur atom  and a nitrogen atom.  [0445]  Examples of the hetero atom-containing linking  group include non-hydrocarbon, heteroatom-containing link› ing groups, such as an oxygen atom (ether bond:  -0-), a  sulfur atom (thioether bond:  -S-),  an  -NH- bond  (H  may be substituted with a substituent such as an alkyl group or  an acyl group), an ester bond  (-COO-),  an amide bond  (-CONH-)  and a carbonyl group  (-CO-),  a carbonate  bond  (-OCOO-);  and a combination of the aforemen› tioned non-hydrocarbon, hetero atom-containing linking  group with the aforementioned alkylene group. An example  of such combination include -R 98  -0- (in the formula,  R$^{98 }$represents an alkylene group). In the formula, the alky› lene group for R$^{98 }$include the same alkylene groups as those  described above as the divalent linking group for R 71 .  [0446]  The divalent linking group for R$^{71 }$is preferably an  oxygen atom, a sulfur atom or  -R $^{98 }$---0-, and an oxygen  atom or -R 98  -0-is particularly desirable.  [0447]  Among these, R$^{71 }$is preferably a single bond or an  alkylene group, and a single bond is particularly desirable.  [0448]  In general formula (blc-0-3), R$^{72 }$represents a group  that is not dissociable by the action of an acid (hereafter,  referred to as "acid non-dissociable group").  [0449]  The acid non-dissociable group for R$^{72 }$is not par› ticularly limited as long as it is a group that is not dissociated  by the action of an acid, and is preferably a hydrocarbon  group that is not dissociated by the action of an acid and  which may have a substituent.  [0450]  The hydrocarbon group for R $^{72 }$may be an aromatic  hydrocarbon group or an aliphatic hydrocarbon group.
