A liquid composition curable by exposure to light of appropriate wavelength, such as ultraviolet light, is a homogeneous liquid containing both vinyl ether groups and maleate or fumarate groups in the presence of a hydroxy or alkoxy-functional acetophenone derivative or a benzoyl diaryl phosphine oxide photoinitiator. These compositions are free from residues of cationic curing catalysts, which cause discoloration and sensitivity to water. Coated metals are better protected against corrosion. Other utilities include use in sterolithography, dentistry, lamination of glass and other fibers and protrusion processes. |
