[0064] L 11 represents a single bond or an m+ 1-valent linking group. 

[0065] The m+l-valent linking group represented by L 11 is not particularly limited, and examples thereof include groups represented by (Al) to (A). Further, in (Al) to (A), *I represents a bonding position to P 11 , and *2 represents a bonding position to y 11 -. 11 

[0066] It should be noted that in a case where y - which will be described later is an anionic functional group represented by General Formula (Y) which will be described later, L$^{11 }$represents *I----CO-O-LsI_*2. LsI represents a divalent linking group which includes no -O----CO-. Further, in a case where y 11 - which will be described later is an anionic functional group represented by General Formula (Y2) which will be described later, L $^{11 }$includes neither a phenylene group nor a lactone structure. 

[0067] The LsI is preferably an alkyl group having 1 to 20 carbon atoms (which may be in any of linear, branched, and cyclic forms).

[0068] In (Al) to (AS), T 11 represents a single bond, a divalent hydrocarbon ring group, or a divalent heterocyclic group, TI $^{2 }$represents a trivalent hydrocarbon ring group or a trivalent heterocyclic group, TI $^{3 }$represents a tetravalent hydrocarbon ring group or a tetravalent heterocyclic group, TI 4 represents a pentavalent hydrocarbon ring group or a pentavalent heterocyclic group, and TI $^{5 }$represents a hexava› lent hydrocarbon ring group or a hexavalent heterocyclic group. 

[0069] The hydrocarbon ring group may be an aromatic hydrocarbon ring group or an aliphatic hydrocarbon ring group. The number of carbon atoms included in the hydro› carbon ring group is preferably 6 to 18, and more preferably 6 to 14. 

[0070] The heterocyclic group may be either an aro› matic heterocyclic group or an aliphatic heterocyclic group. The heterocycle is preferably a 5- to IO-mem› bered ring, more preferably a 5- to 7-membered ring, and still more preferably a 5- or 6-membered ring, each of which has at least one N atom, 0 atom, S atom, or Se atom in the ring structure. 

[0071] In addition, in (Al) to (AS), L$^{2}$I to L 40 each independently represent a single bond or a divalent linking group. 

[0072] Examples of the divalent linking group repre› sented by each of L $^{2}$I to L 40 include -N N-, ---0-, -S-, -NRa-, -CO-, an alkylene group (which may be in any of cyclic, branched, and linear forms), an alkenylene group, an alkynylene group, or a divalent group formed by combination of these groups. Ra represents a hydrogen atom or a substituent (for example, an alkyl group). 

[0073] The alkylene group preferably has 1 to 10 carbon atoms, more preferably has 1 to 6 carbon atoms, and still more preferably has 1 to 4 carbon atoms. 

[0074] The alkenylene group preferably has 2 to 10 carbon atoms, more preferably has 2 to 6 carbon atoms, and still more preferably has 2 to 4 carbon atoms. 

[0075] The alkynylene group preferably has 2 to 10 carbon atoms, more preferably has 2 to 6 carbon atoms, and still more preferably has 2 to 4 carbon atoms. 

[0076] The alkylene group, the alkenylene group, and the alkynylene group represented by each ofL $^{2}$I to L 40 may each have a substituent. As the substituent, a halogen atom is preferable, and a fluorine atom is more preferable. 

[0077] y 11 - represents a group selected from the group consisting of anionic functional groups represented by Gen› eral Formulae (Yl) to (YS).
