Abstract
Official abstract text for this publication.
Catalysts include five-membered nitrogen containing heterocyclic compounds as ligands for metal ions which have catalytic activity. The catalysts are used to electrolessly plate metal on metal clad and un-clad substrates.
First claim

1 - 6 . (canceled) 7 : A catalyst consisting essentially of metal ions and one or more compounds having formula: wherein R 1 may be hydrogen, substituted or unsubstituted, linear or branched (C 1 -C 6 )alkyl, hydroxyl, ester or (C 1 -C 4 )alkoxy; R 2 and R 3 may be the same or different and may be hydrogen, substituted or unsubstituted, linear or branched (C 1 -C 4 )alkyl, hydroxyl, ester (C 1 -C 4 )alkoxy or ureido; and Z is either wherein R 4 and R 5 may be the same or different and may be hydrogen, linear or branched, substituted or unsubstituted (C 1 -C 4 )alkyl, hydroxyl or (C 1 -C 4 )alkoxy; and R 6 may be hydrogen, substituted or unsubstituted, linear or branched (C 1 -C 6 )alkyl, hydroxyl, ester or (C 1 -C 4 )alkoxy. 8 : The catalyst of claim 7 , wherein the one or more compounds are chosen from hydantoin, 1-methylhydantoin, 1,3-dimethylhydantoin, 5,5-dimethylhydantoin, allantoin, 1,3-dihydroxymethyl-5,5-dimethylhydantoin and succinimide. 9 : The catalyst of claim 7 , wherein a molar ratio of the one or more compounds to metal ions is from 1:1 to 4:1. 10 : The catalyst of claim 7 , wherein the one or more compounds are in amounts of 25 ppm to 1000 ppm.
