Aqueous alkaline developable, uv curable urethane acrylate compounds and compositions useful for forming solder mask coatings |
| abstract |
A UV curable, aqueous alkaline developable, urethane acrylate composition characterized by: (a) 40-70% by weight of (i) a urethane acrylate compound which is obtained by reacting substantially equal molar quantities of an aliphatic or cycloaliphatic diisocyanate, and a hydroxyalkyl acrylate, with a polyol having at least three hydroxyl groups, and at least one mole of a dicarboxylic acid anhydride per mole of said polyol; or (ii) a mixture of 20-99 wt. % of said urethane acrylate and 1-80 wt. % of a urethane diacrylate, made by reacting a diisocyanate with 2 moles of a hydroxyalkyl acrylate; (b) 20-50% of a reactive monomer diluent; (c) 0.5-10% of a photoinitiator; and (d) 0-8% of triphenylphosphite. |
