    When 1-Pheyl-5-Mercaptotetrazole (H (PMT)) was crystallized from solutions, two different types of crystals were obtained, depending on the solvent. One, denoted here by (I), crystallized from e.g. benzene solution, while the other, (II), from aqueous ethanol solution. Comparisons of powder X-ray diffraction patterns, results of elemental analyses, IR spectra and melting (decomposition) points of (I) &(II) showed them to be polymorphs.(I) was triclinic with a=9.403 (1), b=11.867 (2), c=3.9615 (5)Å, α=93.92 (1)°, β=95.66 (1)° and γ =68.32 (1)°, whereas (II) was monoclinic with a=12.2, b= 3.95, c=8.81 Å and β =112°. No refinement of the latter parameters could be made because of difficulties in preparing suitable single crystals. The polymorphs could be converted into each other by recrystallizing from appropriate solvents, but could not by varying the temperature. The melting (decomposition) point of (I) (151°C) was slightly higher than that of (II) (145-146°C), the latter being thermally somewhat less stable.

  • Preferred Viewing Illuminant for Japanese-Paper-Albumen-Print
    Hiroko ARAI, Yoichi MIYAKE, Souichi KUBO

    A preferred viewing illuminant for the Japanese-paper-albumen-print is examined. Among the test illuminants, CIE Illuminants D65, C, D50 and A and fluorescent lamp, CIE Illuminant A showed preferable result to the perceived puality of the Japanese-paper-albumen-print. The purpose of this paper is to analyze the reason of the above phenomenon by means of colorimetrical procedure.
    It was found that CIE Illuminant A provides observer's perception of not only reddish sepia tint but also higher saturation and lightness for viewing of the print. This observer's perception is also analytically predicted by examination of colorimetric parameters.

    Fundamental principles and characteristics of excimer lasers are described briefly for the chemists working in the field of imaging technology. The applications of excimer lasers to such imaging technology as contact lithography, self-developing lithography (direct dry photoetching lithography), ablative photodecomposition (UV-laser ablation), projection lithography, and producing gratings and printing plates are reviewed.

    Radical photoinitiated polymerization system of improved sensitivity for image recording are reviewed. Researches include (1) screening the improved photoinitiating system consisting of an effective radical precursor and a sensitizer, (2) selecting monomers which polymerize to be an insoluble, crosslinked polymer effectively and (3) constituting a polymer binder in which the monomers can rapidly polymerize to make the binder insoluble.
    Application of radical “living polymerization” re-initiated by an iniferter (initiator-chain transfer agent-terminator) might be another way to improve the intrinsic sensitivities of photopolymerizing systems. Forty references are cited.
