  • Electron beam recording media containing 4,4'-bis(3-diazo-3,4-dihydro-4-oxo-1-naphthalene-sulfonyloxy)benzil
    Patent number: 4065306
    Abstract: Recording media comprising a mixture of 4,4'-bis(3-diazo-3,4-dihydro-4-oxo-1-naphthalenesulfonyloxy)benzil and an alkali soluble resin are suitable for recording information with electron beams. These recording media have high sensitivity, high resolving power and can be reproducibly formulated.
    Type: Grant
    Filed: August 23, 1976
    Date of Patent: December 27, 1977
    Assignee: RCA Corporation
    Inventors: Daniel Louis Ross, Lucian Anthony Barton
  • Method of purifying 2,4-bis(6-diazo-5,6-dihydro-5-oxo-1-naphthalenesulfonyloxy benzophenone)
    Patent number: 4024122
    Abstract: A method of purifying crude 2,4-bis(6-diazo-5,6-dihydro-5-oxo-1-naphthalenesulfonyloxy)benzophenone by dissolving in an organic solvent, reprecipitating by adding certain nonsolvents and recrystallizing the reprecipitated product from certain solvents.
    Type: Grant
    Filed: September 11, 1974
    Date of Patent: May 17, 1977
    Assignee: RCA Corporation
    Inventors: Daniel Louis Ross, Lucian Anthony Barton

    Type: Grant
    Filed: April 18, 1975
    Date of Patent: January 25, 1977
    Assignee: RCA Corporation
    Inventors: Daniel Louis Ross, Lucian Anthony Barton
  • Process for improved development of electron-beam-sensitive resist films
    Patent number: 3961101
    Abstract: The development of an exposed electron beam sensitive resist film in a two-stage process, rather than in a single stage, with a water wash between stages, improves the sensitivity and resolution that can be achieved for the resist.
