94  93  US 9,052,590 B2  -continued  -continued  (VI-112)  (VI-107)  (VI-108)  (VI-109)  (VI-110)  (VI-111)  (V-1)  Particular examples of the repeating units of general for› mula (V’) will be shown below, which however in no way  limit the scope of the present invention.  L’s,  R’ss  and R’s$_{6 }$ have the same meanings as those of Ls,  Rss  and Rs$_{6 }$ of general formula (V), respectively, except that  L’s,  R’ss  and R’s$_{6 }$are neither aromatic ring groups nor groups  having aromatic ring groups.  In general formula (V’), Rs$_{1 }$ to Rs$_{4 }$ are as defined above in  connection with general formula (V).  The repeating unit (C) is preferably any of those of general  formula (V’) below.  The resin (P) may further contain a repeating unit (C) that  contains an acid-decomposable group but does not contain  any aromatic ring group.  [Repeating Unit (C)]  The ratio between repeating unit (A) and repeating unit  (B2) (number of moles of A/number of moles of B) in the  resin is preferably in the range of0.04 to 1.0, more preferably  0.05 to 0.9 and most preferably 0.06 to 0.8.  In the resin (P) of the present invention, the content of  repeating units containing acid-decomposable groups (in› cluding the repeating unit (B2) and the repeating unit (C) to be  described hereinafter), based on all the repeating units of the  resin, is preferably in the range of 3 to 90 mo!  %, more  preferably 5 to 80 mo!  % and most preferably 7 to 70 mo! %.
