The sensitivity of films sensitised by 3,3’-diethyl-5,6,5’,6’-bis- （15-crown-5） thiacarbocyanine- iodide （Ⅰ）,（Ⅰ）KCI and （Ⅰ）CaCl 2 was the same as that sensitized by 3,3’-dimethyl-9-ethyl-β-naphthyl-thiacarboeyanine chloride （V）.Film sensitized （Ⅰ）NaCl was 1 DIN more sensitive than thai sensitized by（V）. 1984-04-01 2021-04-01 4
