From F. M. Hamer, Q2cart. Revs. London, 4, 327 (1950), Plate I . ll For various scientific purposes it is convenient to have photographic material which is sensitive to a particular region of the spectrum. Photography in colour depends on the availability of Photographic material which has been sensitised to different colours. Some cyanines absorb infrared light and sensitise to the infrared. Dicyanine (see section 3-G) was an early infrared sensitiser, which was used for spectrum photography,la but kryptocyanine (see section 3°F; IV-2-C) was easier to use; by means of it, the most distant photographs on record were taken by A.

5. Cyanines in which the Nucfei are Directly Linked (Apocydnes) A. General According to a patent of 1903,81the action of caustic alkali on hot alcoholic solutions of quinoline alkiodide gave red and yellow dyes, which differed from cyanine and isocyanine in that their aqueous solutions were not instantly decolorised by mineral acids. The compounds prepared from quinoline ethiodide, methiodide, and methochloride, and from some substituted quinolinium alkiodides were specified. Both types were said to be useful in photography, but no details were given.
