INVESTIGATION OF THE PHOTOPOLYMERIZATION PROCESS

Abstract

Photopolymerizable coatings were prepared from formulations containing (a) manganic ion, an organic acid and monomer, (b) manganic ion, a light-sensitive ferric salt and monomer, and (c) manganic ion, a light-sensitive ferric salt, mercuric chloride, and monomer. Such coatings require only waterwash after exposure to produce a resist. Required minimum exposure varies with formulations used, but is in most cases longer than that required for ferric salt-peroxide coatings. Stability of coatings tested did not exceed two weeks. A print out process was developed from ferric ammonium citrate and sodium manganic pyrophosphate, when monomer is omitted. The polymerization of acrylamide was controlled so as to yield a water-soluble product, useful as a colloid-type carrier for coating ferric salts (such as glyoxylate) which are not compatible with gelatin. Benzoyl leucomethylene blue does not initiate polymerization of vinyl monomers. (Author)
