Abstract
Alcohol solutions for use as fountain solutions in the printing industry are disclosed. The solutions include isopropyl alcohol in amounts of 40% to 95%, ethyl alcohol or other alcohols in amounts of 5% to 60% and ethylene diamine in an amount of 0.015% to 0.040%. The addition of a small amount of ethylene diamine markedly reduces the emission of fumes from the fountain solutions.
