| abstract |
An improvement in the method of effecting polymerization and particularly visible light photopolymerization of photopolymerizable ethylenic systems, or compositions thereof, by the use of a mixture of a selective combination of photo-oxidant dye material and catalyst cooperative therewith in initiating polymerization in combination with a light sensitizing activator to induce the reaction of said selective combination and to effect more rapid polymerization, and compositions thereof and therefor. |
