    In a diffusion-transfer-color-development which utilizes non-diffusible color coupler (yellow) releasing diffusible (magenta) dye, acceleration on color development and transfer of released dye images is observed in the case when some of polymethylene-polyamines are introduced in developer.
    In a series of 1, n-diamino-n-alkane NH2-(CH2) n-NH2 with 10% addition of ethanol, accelerating activities increases in linear relation to the increase of chain length of carbon number (n) from 2 to 8, then activity abruptly decreases (at n=10), and finally even retardation is observed (at n=12). In general, including a series of type NH2-[(CH2) n-NH] m-(CH2) n-NH2 polyamines, specific activities (As) vary linearly with equivalent chain length or chain numbers (NE) calculated upon some assumptions, according to the equation; NE = 3As + 2.5.
    Effects of addition of various alcohols to the developer with or without a diamine accelerator are also studied and found to be sharply dependent on the chain length of alcohols.
    It is concluded that acceleration occurs mainly in transfer stage of released dyes to a mordant layer and the mechanism is closely related to a surface-chemical phenomenon which involves a formation of micelles consisting of released anionic dyes and molecules of polymethylene-polyamines, sometimes together with alcohols, and the mechanism is also related to charge neutralization of the anionic dyes in the micelles by chelation with the polymethylenepolyamines for easier migration and transfer through layers.

    Photodegradation and UV lithographic characteristics of poly (tert-Butyl vinyl ketone) and its copolymers of methyl methacrylate and styrene were investigated in solution and film state.
    Photodegradation of these polymers takes place th ough Norrish type I reaction.
    The degradations of poly (tert-Butyl vinyl ketone) and its copolymer were decreased in the presence of oxygen.
    It was found that photodegradations of these polymers were increased with increase of irradiation temperature.
    The irradiated films were effectively developed by several developer.

  • Formation of Metal Image by a New Peel Apart System (III)

    A new type imaging system based upon the peel apart procedure has been described. In this system metal images are formed by using the sensor which consists of a photosensitive layer and a thin metal layer deposited on a substrate.
    In this paper, the peel force between the photosensitive layer and the metal layer was measured by changing the process factors such as, the concentration of the photosensitive materials, the thickness of the photosensitive layer and the heating period after exposure. The experimental results indicated that light illumination caused a change in the adhesive force between the photosensitive layer and the metal layer. Heat-treatment resulted in “ Fogging ” under certain conditions because the adhesive force between the metal layer and the substrate was decreased. An intermediate layer of PVC between the photosensitive layer and the metal layer accounted for decreasing fog and increasing the shelf life.
