studied. Those substrates possesing an electron-withdrawing group in a 1,3 relationship with the coordinating (-CH2OMe) group underwent regioselective metalation by the action of n-BuLi/THF. Highlysubstituted phenols can thus be readly prepared.
An electrophotographic lithographic printing plate precursor which utilizes an electrophotographic light-sensitive material comprising a conductive support having provided thereon at least one photoconductive layer containing photoconductive zinc oxide and a binder resin, wherein the binder resin contains at least one graft-type copolymer comprising at least (1) a monofunctional monomer containing a functional group which has at least one atom selected from a fluorine atom and a silicon atom and is capable of forming at least one hydrophilic group selected from a sulfo group, a phosphono group, a carboxy group and a hydroxy group through decomposition, and (2) a monofunctional macromonomer which has a weight average molecular weight of from 1.times.10.sup.3 to 2.times.10.sup.4, and has a polymerizable double bond group represented by the general formula (I) described herein bonded to only one terminal of the main chain thereof.
