ABSTRACT:
The present invention resides in the discovery that ethylenically unsaturated organic compounds can be readily photopolymerized by adding to such compounds a catalytic formulation including certain FDA approved food color additives and an amount of an organic amine activator. Particularly improved results are obtained by employing as said food color additive the combination of FD&C red No. 3 dye, with either FD&C red No. 2 dye, FD&C red No. 40 dye, or with both FD&C red No. 2 and FD&C red No. 40 dyes.
