  • N,N'-diorgano dicarboxamides as oxygen inhibitors in radiation sensitive acrylate compositions
    Patent number: 4782005
    Abstract: Radiation sensitive compositions comprising acrylic or methacrylic acid esters with decreased oxygen inhibition attained by use of minor amounts of N,N'-diorgano dicarboxamide additives. The acrylated ester compositions are suitable for ultraviolet curable coatings.
    Type: Grant

  • Water developable diazo printing plate composition with quaternary nitrogen stabilizer
    Patent number: 4568628
    Abstract: A water developable printing plate is provided with a photopolymerizable system as a latex comprising a water soluble diazopolymer reaction product of a diazoaryl amine and an aldehyde and an aqueous cationic or nonionic dispersion of a water insoluble polymer. The inclusion of a water miscible organic solvent improves the shelf-life of the photopolymerizable system and the printing plate especially under high humidity conditions.

  • Planographic printing plate having cationic compound in interlayer
    Patent number: 4552827
    Abstract: An improved planographic printing plate comprised of a metal substrate, a sealing layer, an interlayer formed from a monomer or polymer of an organic compound having at least one cationic, quaternary substituted ammonium group, and a photosensitive layer on the surface of the interlayer. The printing plates are water developable and characterized by cleaner non-imaging areas during printing operations. The method of preparing such planographic printing plates is also described and illustrated.
