  • Patent number: 4049452
    Abstract: In the method disclosed, a supporting surface, such as the inner surface of the faceplate of the tube, is coated with a photosensitive polymeric film containing about 5 to 80 weight percent of at least one member of the group consisting of certain diol ethers and diol alkanes. Then the film is exposed to a light image to produce regions of greater solubility and regions of lesser solubility. The film regions of greater solubility are removed, and then the entire faceplate with its regions of less solubility is overcoated with a layer containing particles of screen structure material. The retained film regions and the overcoating thereon are removed leaving the screen structure adherent in the areas of greater solubility. By including a diol ether or diol alkane in the film, the exposure time may be shortened significantly without substantial loss of adherence.
