Abstract : With the objective of improving the speed of dye-sensitized photopolymerizable compositions, the effectiveness of several electron donors was studied in conjunction with photoreducible dyes. N-phenylglycine was more effective than N phenyliminodiacetic acid and more stable than N-phenyl N-methylglycine. High monomer concentration favored formation of a resist with relatively short exposures when an optimum ratio of electron donor to dye was employed. Increased speed of photopolymerizable compositions sensitized by ferric ammonium oxalate, was achieved by addition of relatively high concentrations of acrylamide to several formulations saturated with N,N'-methylenebisacrylamide. A water soluble sulfonated derivative of cumene hydroperoxide was prepared and found to be satisfactory in photopolymerizable coatings. Use of acrylated gelatin in coatings containing ferric ammonium oxalate and N,N'-methylenebis acrylamide gave a 3.5 stop increase in speed over control coatings prepared with ordinary gela/in.
