ABSTRACT:
Acid-curable thermoset enamel compositions coming in contact with copper or copper-containing alloys are discolored and degrade more rapidly due to leaching of copper into the compositions. The presence of small amounts of benzotriazole or tolutriazole effectively prevents the discoloration and concomitantly retards degradation.
