Abstract

Reaction products of guanidine compounds or salts thereof, polyepoxide compounds and polyhalogen compounds may be used as levelers in metal electroplating baths, such as copper electroplating baths, to provide good throwing power. Such reaction products may plate with good surface properties of the metal deposits and good physical reliability.
