Abstract
Abstract This invention is directed to photocopolymerizable compositions comprising an epoxide containing two or more epoxy groups, a poly (active hydrogen) organic compound, a photoinitiator and, as a reactive diluent, a substituted cycloaliphatic monoepoxide. The photocopolymerizable compositions have low viscosity and can be applied to suitable substrates by conventional methods and, after being cured to dry coating films, can have utility as automotive finishes, can finishes, appliance finishes, general metal finishes, adhesives, printing inks and the like.
