In formula (3b ), RO and R $^{1 }$are as defined above. When q is  equal to 0, p is a substituted or unsubstituted C$_{1 }$-C$_{20 }$ alkyl  group or a substituted or unsubstituted C$_{6}$-C$_{15 }$ aryl group.  When q is equal to 1, p is a single bond, a substituted or  unsubstituted C$_{1 }$-C$_{20 }$ alkylene group or a substituted or  unsubstituted  CcC$_{15 }$ arylene group. EWG is a cyano, trifluo› romethyl, perfluoroethyl, perfluoropropyl, 5H-perfluoropen› tyl, 6H-perfluorohexyl, nitro or methyl group. When q is  equal to 1, two EWG’s may bond together to form a ring of 6  carbon atoms with the carbon atoms to which they are  attached. The skeletons of the oxime sulfonates are described  in U.S. Pat. No. 6,261,738, JP-A 9-95479, JP-A 9-208554,  JP-A 9-230588, JP 2,906,999, JP-A 9-301948, JP-A 2000- 314956, JP-A 2001-233842, and WO 2004/074242.  Exemplary skeletons of oxime sulfonates excluding the  sulfonate moiety are given below wherein the broken line  denotes a bonding site to the sulfonate moiety.  A further embodiment of the invention is an oxime sul› fonate compound having the general formula (3b ).  ~N---- ~N---- .>-----N---- ,r--=N-- -- ,r--=N---- ,>-----N---- ,r---N-- -- Oxime Sulfonate  -continued
