A sprayable energy-curable coating composition comprises an epoxide monomer or oligomer, a cationic photoinitiator, and a cyclic carbonate, wherein the cyclic carbonate is present in an amount of at least 7 wt. % based on the composition. The cyclic carbonate may be present in an amount of 8-35 wt. %, preferably 15-25 wt. % and may be selected from propylene carbonate, glycerine carbonate, vinyl ethylene carbonate, ethylene carbonate, or butylene carbonate. The composition may additionally comprise an oxetane, which may be in the form of a monomer or a polymer. The composition may have a viscosity of 7-50 cps at 25{C and may be a varnish, paint, or printing ink especially when formulated for inkjet printing. A process for preparing a cured coating composition is also disclosed, wherein the composition is applied to a substrate before exposure to radiation to cause curing. The radiation is typically ultraviolet radiation. |
