Photography developers

Materials such as methyl alcohol, acids, ammonia, irritating gases, mercury compounds, and photography developers can cause eye irritation if splashed into the eye. With prolonged contact, eye inflammation and even cataracts can result.

Use Textiles, manufacture rayon, rubber, fertilizers, refrigeration, condensation polymerization, photography (development of latent images), pharmaceuticals, ammonia soaps, lubricants, fireproofing wood, ink manufacture, explosives, ceramics, ammonium compounds, saponifying fats and oils, organic synthesis, detergents, food additives, household cleanser. 

Use Textile industry, photography (developers), coloring brasses, bronzes, iron control in soda ash production, synthetic flavors. 

Benzothiazines have been used in industry as dyes and as antioxidants of rubber and natural elastomers. They have been used widely to prepare azodye compounds with specific properties, such as water insolubility, which is useful in the dyeing of polypropylene fibers, and increased stability to gas fading.72,73 Several reports are concerned with the antioxidant properties of benzothiazines,74-77 and their use as color photography developers.78... 

MAJOR USES Used in the production of foods, rubber, dyes, paints, varnishes, acrylic monomers, motor fuels, oils and pharmaceuticals photography development polymerization inhibitor. 

One way to make sodium thiosulfate, known as hypo and used in photographie developing, is described by the equation Na2COj + 2 NajS + 4 SOj 3 Na2S203 + CO2. How many grams of sodium carbonate are required to produce 681 grams of sodium thiosulfate ... 

It is used for hair dyeing, as a rubber accelerator and as a photographic developer. Derivatives are extensively used as developers in colour photography. 

Photography. Photography (qv) represents one of the oldest industrial uses of iodide. The sensitive silver salt in rapid negative emulsions contains up to 7% or mote silver iodide [7783-96-2], Agl. Erom 1969 to 1985 estimates on iodine consumption for this purpose varied from 150 to 270 t/yr (66). Ttiphenylphosphonium iodide is also among the iodine derivatives used in photography. This derivative permits faster development and higher contrast photography. 

Phthalocyanines have been used to incorporate semiconductor properties in polymers (182) or to develop a thin-film transistor (183). Phthalocyanines and their derivatives can act as dyes in color photography (qv) (184) or electrophotography (185). Light-sensitive compositions for use on Hthographic plates are comprised in part of copper phthalocyanine blue (186). Dichlorosilicon phthalocyanine [19333-10-9] has been used in the... 

Miscellaneous. Chloroplatinic acid is used in the production of automobile catalysts. Platino-type prints based on reduction of Pt(II) to Pt(0) by a photosensitive reducing agent such as iron(III) oxalate are used in art photography (261,262). Infrared imaging devices based on a platinum siLicide detector have been developed (263).
