-continued  16  US 10,394,127 B2  15  monocyclic cycloalkyl group having 3 to 8 carbon atoms,  such as a cyclopropyl group, a cyclopentyl group, and a  cyclohexyl group.  The aryl group as R$_{03 }$or R$_{019 }$is preferably an aryl group  having 6 to 15 carbon atoms. Examples of such the aryl  group include a phenyl group, a tolyl group, a naphthyl  group, and an anthryl group.  The aralkyl group as R$_{03 }$or R$_{019 }$is preferably an aralkyl  group having 6 to 20 carbon atoms. Examples of such the  aralkyl group include a benzyl group and a phenethyl group.  Each of these alkyl, cycloalkyl, aryl, and aralkyl groups  may have a substituent. Examples of this substituent include  a hydroxyl group; a halogen atom such as fluorine, chlorine,  bromine, and iodine atoms; nitro group; cyano group; amido  group; a sulfonamido group; an alkyl group such as a methyl  group, an ethyl group, a propyl group, an isopropyl group,  an n-butyl group, a sec-butyl group, a hexyl group, a  2-ethylhexyl group, an octyl group, and dodecyl group; an  alkoxy group such as a methoxy group, an ethoxy group, a  hydroxy ethoxy group, a propoxy group, a hydroxypropoxy  group, and a butoxy group; an alkoxycarbonyl group such as  a methoxycarbonyl group and an ethoxycarbonyl group; an  acyl group such as a formyl group, an acetyl group, and a  benzoyl group; an acyloxy group such as an acetoxy group  and a butyryloxy group; and a carboxy group. Further, these  substituents preferably have 8 or less carbon atoms.  The arylene group as Ar$_{1}$ a  preferably has 6 to 14 carbon  atoms. Examples of such the arylene group include a phe› nylene group, a tolylene group, and a naphthylene group.  This arylene group may have a substituent. Examples of  this substituent include the same substituents as those  described for R$_{03 }$ and  R$_{019 }$ above.  Examples of a preferred partial structure of General  Formulae ( 1-1) and ( 1-1 ’) ( a partial structure other than X or  H and a partial structure represented by General Formula  (1-1-2). Ra, Rb, Re, and L$_{1 }$ have the same definitions as  those in General Formula (1-1), respectively) include the  following ones.  * Lt  ib i•  ,tn  L1  I  O=S=O  I  0  I  (1-1-2) 40  0-0-S03- •~•  C=O  I  O~S03- •~•  C=O  I  0~  S03-
