On May 9, 1990, Metoki, Iku; Sato, Kiyoshi published a patent.Electric Literature of 26172-54-3 The title of the patent was Photographic material with excellent antislatic properties. And the patent contained the following:
A high-sensitivity photog. material having improved antistatic properties at high humidity is composed of a support and ≥1 Ag halide photosensitive layer spectrally sensitized by adding a spectral sensitizer during the grain formation process, the phys. ripening process, and the desalting process, and also containing a 3-isothiazolinone derivative (I; R1 = H, alkyl, cycloalkyl, alkenyl, aralkyl, alkoxy, aryl, heterocyclyl, carbamoyl, thiocarbamoyl, and sulfamoyl; R2, R3 = H, halogen, alkyl, cycloalkyl, aryl, CN, alkylthio, arylthio, alkylsulfoxide, alkylsulfonyl, heterocyclyl, or R2 and R3 together can form a benzene ring). Thus, a PET film was coated with a gelatin-Ag halide emulsion (the spectral sensitizer was added after the grain growth process) containing II. The resultant emulsion showed a relative sensitivity of 130 and a surface sp. resistance (at 20° and 55% relative humidity) of 7 × 1011. The experimental process involved the reaction of 2-Methylisothiazol-3(2H)-one hydrochloride(cas: 26172-54-3).Electric Literature of 26172-54-3
