Further, examples of the substituent for the phenyl group or  naphthyl group represented by R $^{9 }$include the same groups as  those described above for substituents which the substituted  aryl group represented by R 1 " to R 3 " may have. Specific  examples thereof include an alkyl group, an alkoxy group, a  halogen atom, a halogenated alkyl group, a hydroxy group, an  oxo group (=0), a cyano group, an aryl group, an alkoxy› alkyloxy  group,  an  alkoxycarbonylalkyloxy  group,  -C(=0)---0-R 6 ’,  -0----C(=0)-R 7 ’,  ---O-R 8 -0-R 9 ’,  a halogenated alkylsulfonyoxy  group  and  -0-Ql-[0-Rll11_s+(R2111)(R3111)lx•  As the alkyl group which may have a substituent for R 9 ,  the  same alkyl group which may have a substituent as those  described above for R 1 " to R 3 ".  R $^{10 }$represents a phenyl group, a naphthyl group, an alkyl  group and an alkoxy group which may have a substituent.  In the formulas (ca-14) and (ca-15), u is an integer of 1 to  3, and most preferably 1 or 2.  R $^{9 }$represents a phenyl group, a naphthyl group or an alkyl  group which may have a substituent.  -continued  Examples of the substituent for the phenyl group or naph› thyl group represented by R$^{10 }$include the same groups as  those described above for substituents which the phenyl  group or naphthyl group represented by R $^{9 }$may have.  As the alkyl group in the alkyl group and alkoxy group  which may have a substituent for R  10 , the same alkyl group as  those described above for R 1 " to R 3 " can be mentioned.  As the alkylene group for R 4 ’,  a linear or branched alkylene  group is preferable. The alkylene group preferably has 1 to 12  carbon atoms, more preferably 1 to 5 carbon atoms, and most  preferably 1 to  3  carbon atoms.  Further, examples of the substituent which the alkylene  group represented by R 4 ’  may have include the same groups  as those described above for substituents which the substi› tuted alkyl group represented by R 1 " to R 3 " may have. Spe› cific examples thereof include an alkoxy group, a halogen  atom, a halogenated alkyl group, a hydroxy group, an oxo  group (=0), acyano group, anaryl group, analkoxyalkyloxy  group, an alkoxycarbonylalkyloxy group, -C(=0)-0- R 6’, -0----C(=0)-R 7 ’, ---O-R 8 ’, ---O-R 9 ’, a haloge› nated alkylsulfonyoxy group and ---O-Q 1 -[0-R $^{11}$"-S+  (R21")(R31")lx•  Preferable examples of the cation represented by the for› mula (ca-14) or (ca-15) are shown below.
