-continued  In the case of containing a silicon atom, the hydrophobic  resin (HR) is preferably a resin having, as a silicon atom› containing partial structure, an alkylsilyl structure (prefer- ably a trialkylsilyl group) or a cyclic siloxane structure.  The alkylsilyl structure or cyclic siloxane structure specifi› cally includes, for example, the groups represented by the  following formulae (CS-1) to (CS-3):  In formulae (CS-1) to (CS-3), each ofR$_{12 }$to R$_{26 }$indepen› dently represents a linear or branched alkyl group (preferably  having a carbon number of 1 to 20) or a cycloalkyl group  (preferably having a carbon number of 3 to 20).  Each of L$_{3 }$ to L$_{5 }$ represents a single bond or a divalent  linking group. The divalent linking group includes a single  group or a combination of two or more groups, selected from  the group consisting of an alkylene group, a phenylene group,  an ether group, a thioether group, a carbonyl group, an ester  group, an amide group, a urethane group and a urea group.  n represents an integer of 1 to  5. n is preferably an integer  of2 to 4.  Specific examples of the repeating unit having a group  represented by formulae (CS-1) to (CS-3) are illustrated  below, but the present invention is not limited thereto. In  specific examples,  X$_{1 }$ represents a hydrogen atom, ----CH$_{3}$ ,  -F  or  --CF  3 •  -continued  88  US 9,069,246 B2  87  (CS-3)  I  Ls  R20  \  /  /Si-07Si  R 22 -......  __,..o  I  .,..o  I  Si-O-Si-R21  I  6  I  o  O  I O  I  I  R23 _,....Si-1-0 /Si,  __,..O  _,..0  R24  Si-0-Si  R2l’_,..  \  R2s  (CS-2)  (CS-1)  [Chem.46]
