Abstract
Reaction products of heterocyclic nitrogen compounds, 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 metal with good surface properties and good physical reliability.
