The addition of minor amounts of acrylic acid to radiation curable compositions containing unsaturated addition-poly-merizable urethane resin and reactive monomer diluent is effective in reducing viscosity and thixotropy of the compositions and in inhibiting separation of the resin phase from the diluent phase. In addition, acrylic acid has been found to render unsaturated addition-polymerizable urethane resins more compatible with higher molecular weight reactive monomer diluents. |
