A resist composition comprises a metal compound obtained from reaction of a starting metal compound having formula (A-1) or a (partial) hydrolyzate or condensate or (partial) hydrolytic condensate thereof, with a di- or trihydric alcohol having formula (A-2). 1. A resist composition comprising a metal compound obtained from reaction of at least one metal compound selected from the group consisting of a metal compound having the general formula (A-1) and a metal compound obtained from (partial) hydrolysis or condensation , or (partial) hydrolytic condensation of the metal compound of formula (A-1) , with a di- or trihydric alcohol having the general formula (A-2) ,{'br': None, 'sup': '1A', 'sub': '4', 'M(OR)\u2003\u2003(A-1)'}{'sup': '1A', 'sub': 1', '6, 'claim-text': {'br': None, 'sup': '2A', 'sub': 'm', 'R(OH)\u2003\u2003(A-2)'}, 'wherein M is an element selected from the group consisting of titanium, zirconium, and hafnium, and Ris a straight or branched C-Calkyl group,'}{'sup': 2A', '2A, 'sub': 2', '20', '1', '6, 'wherein m is 2 or 3, when m is 2, Ris a divalent group selected from the group consisting of a straight, branched or cyclic C-Calkylene, alkenylene, alkynylene or aralkylene group, a straight or branched alkylene group substituted with a cyclic alkyl, cyclic alkenyl or aryl moiety, and a straight or branched alkylene group having an intervening cyclic alkylene, cyclic alkenylene or arylene moiety, said divalent group may have a cyano moiety or be separated by a carbonyl, ester, ether, thiol or NR moiety wherein R is hydrogen or a straight or branched C-Calkyl group, and when m is 3, Ris a trivalent group corresponding to the divalent group with one hydrogen eliminated.'}2.
