<p>Novel urethane compounds, which are derivatives of 1halogen substituted lower molecular weight alkynes having the formula wherein R is alkyl of 1 to 20 carbon atoms, alkenyl of up to 20 carbon atoms, e.g. allyl, cycloalkyl of up to 20 carbon atoms, e.g. cyclohexyl and aromatic hydrocarbon of up to 20 carbon atoms, e.g. phenyl and having from one to three linkages corresponding to m, and "m" and "n" are whole number integers between 1 and 3 and may be the same or different; provided that when m and n are both 1, R is other than aromatic hydrocarbon. These compounds have shown great fungicidal activity and particularly when used in surface coating compositions such as paint formulations.</p> |
