    Theories of the photosensitive glass are reviewed in this article. Since a new type of photosensitive glass was discovered about 25 years ago at Corning Glass Company, various developments and applications of it have been made. In Chapter 2, general theory of photosensitive glass, (composition, theory of photosensitivity, kinetics of crystallization) is summarised. The applications of it, such as glass ceramics, photochromic glass and photosensitive materials available at high temperature, are summarised in Chapter 3. The last section about the photosensitive materials available at high temperature is developed on the basis of original views.

    Equilibrium constants for the addition of proton and bisulfite ion to 14 indaniline dyes were spectrophotometrically determined. determined. The pK value decreases with some exceptions almost linearly as the λmax increases. The fact is explained by considering the stability of each of the cononical structures.
    The equilibrium constant for the addition of bisulfite ion increases as the absorption maximum shifts toward longer wave lengths. This can be interpreted from the electronic point of view if we assume that the addition takes place at position 3 of the naphoquinone ring, disagreeing with the conclusion of Reeves and Tong. We cannot explain, however, why the adduct will not isomerize to accomplish aromatization as the authors suggested that it would.

    A micro-separation and determination method for nonionic, cationic and anionic surfactants in the photographic emulsion was described.
    Nonionic surfactant and anionic-cationic surfactant complex in the photographic emulsion was extracted with good yield using ethylalcohol but anionic surfactant was not good. When pH of the photographic emulsion raises to 12-13, yield of the anion surfactant increases remarkably.
    An extracted surfactants mixture was separated to cationic, anionic and nonionic surfactant using sephadex SE-[SO3H+]-DEAE-[OH-] columns.
    Sephadex columns shows good sorption and desorption behavior for surfactants than other ionexchanger adsorption columns as for resin and cellulosic.
    Sephadex SE column caught the cationic surfactant and DEAE column also caught the anionic, but the nonionic substances passed through in-to effluent.
    The isolated ionic surfactants were determined by photometrically. The nonionic surfactants were separated by paperchromatography and identification methods for saponin, alkylene oxide condensate derivatives, carbwax and PEG were also investigated.

    The recommended formuras of monobath of developer-fixer were tried for several films. The results show that they give an enough sensitivity, higher gamma than D-76 and a satisfactory low fog level. The paste form of monobath was also used. The application of monobath for papers did not give the good results, because the silver image took a brownish colour for some kinds of paper.
