Claims8
An ultraviolet radiation curable vehicle consisting essentially of (a) 1-25%, by weight, of a blend of a difunctional or trifunctional polyester acrylate or methacrylate and 1-25%, by weight, of a difunctional or trifunctional polyurethane acrylate or methcacrylate;
- (b) 10-50%, by weight, of at least one monofunctional polyether acrylate or methacrylate;
- (C) 1-35% by weight, of at least one pentafunctional aliphatic pentaacrylate or pentamethacrylate;
- and (d) a blend of0.5-5.0%, by weight, of a substituted thioxanthone compound, 0.5-5.0%, by weight, of an ester of an aminobenzoic acid and 0.5-15.0%, by weight, of a 2-phenyl acetophenone derivative.
