<p>A photosensitive, solventless, low viscosity, oil free coating composition is made by admixing: (A) about 40 wt.% to about 90 wt.% of an alkyd component, consisting essentially of a polyhydric alcohol and a dibasic aromatic and aliphatic acid mixture with (B) about 10 wt.% to about 60 wt.% of an acrylate monomer and (C) an effective amount of a photoinitiator; the composition characterized by having a viscosity of up to about 2,000 cps. at 25 DEG C., and being capable of forming an ultraviolet radiation cured, hard, pin hole free film, having a thickness of under about 5 mils.</p> |
