Photographic chemistry

The unreduced silver halide must then be completely removed by com-plexation with Na2S20s or (NH4)2S203 solution  [Pg.255]

Within (say) the red-sensitive layer of a color-negative film, silver halide grains become sensitized by red light to form a latent image and are reduced to silver metal by a developer just as in black-and-white photography. In [Pg.255]


An illustration of the technological significance of the relaxation phenomenon can be taken from photographic chemistry. Dyes of the cyanine class where Y = S, 0, CH—CH— n = 0,1,2,3...X = haUde, etc, are used as spectral sensitizers to extend photochemical response of the photographic silver hahdes, which only absorb blue and ultraviolet light, into the visible spectral regime. [Pg.389]

BAEKELAND, L. EL (1863-1944). Born in Ghent, Belgium. He did early research in photographic chemistry and invented Velox paper (1893). After working for several years in electrolytic research, he under took fundamental study of the reaction products of phenol and formaldehyde, which culminated in his discovery in 1907 of phenol-formaldehyde polymers originally called Bakelite. The reaction itself had been investigated by Bayer in 1872, but Baekeland was the first to learn how to contiol it to yield dependable results on a commercial scale, The Bakelite Co, (now a division of Union Carbide) was founded in 1910. [Pg.170]

Sodium carbonate is one of the most commonly used ingredients in photographic chemistry. [Pg.330]

The discussion above grossly oversimplifies the complexity of silver halide photographic chemistry. A more detailed discussion is beyond the scope of this review. The interested reader is referred to monographs on the topic [7]. More germane to the present review is the evolving picture of the electron transfer photochemistry which occurs during the spectral sensitization of silver halide materials. [Pg.204]

Baekeland, Leo Hendrik A scientist born in Ghent, Belgium (1863—1944), who did early work in photographic chemistry and invented Velox paper (1893). After moving to the United States, he discovered the phenol-formaldehyde plastic originally called Bakelite (1909). [Pg.105]
