In General Formulas (aal-2-2) and (aal-3-2), Ra$_{1 }$and Ra$_{2 }$ each independently represent a hydrogen atom or an alkyl group. 

R$_{1}$ , R$_{2}$ , R$_{3}$ , and R$_{4 }$ each independently represent a hydro› gen atom or an alkyl group. 

m $_{1 }$ and m$_{2 }$ each independently represent an integer of O to 5. 

Rf$_{1 }$ and Rf$_{2 }$ each independently represent an organic group which has a fluorine atom. 

Ra$_{1 }$ and Ra$_{2 }$ are preferably a hydrogen atom or a methyl group. 

An alkyl group which is represented by Ri, R$_{2}$ , R$_{3}$ , and R$_{4 }$ is preferably, for example, a straight-chain or branched chain alkyl group with 1 to 10 carbon atoms. The alkyl group may have a substituent group and examples of the substituent group include an alkoxy group, an aryl group, a halogen atom, and the like. 

m$_{1 }$ and m$_{2 }$ are preferably an integer of O to 3, more 60 preferably O or 1, and most preferably 1. 

The organic group which has a fluorine atom as Rf$_{1 }$ and Rf$_{2 }$ is the same as Rf in General Formula (aal-1). 

In addition, in one aspect, the repeating unit (y) is pref- erably a repeating unit which is represented by General Formula (aal-2-3) or (aal-3-3) below.

(aal-3-2) 

In General Formulas (aal-2-3) and (aal-3-3), Ra$_{1 }$ repre- sents a hydrogen atom or a methyl group. 

Rf$_{1 }$ and Rf$_{2 }$ each independently represent an organic group which has a fluorine atom and are the same as Rf in General Formula (aal-1). 

Specific examples of the repeating unit (y) will be shown below; however, the present invention is not limited thereto.
