Photochemical Stability of Dyes in the Solid State

IT has recently been shown1 that it is possible to produce level transparent dye films upon thin quartz plates by the method of vacuum deposition. This technique makes it possible to compare under similar conditions the photochemical stability of dyes in the solid state with their stability when present as a dyeing on a polymer film. For this purpose we have used several aminoanthraquinone compounds purified by repeated recrystallizations from ethyl alcohol. Polymer films were dyed with these compounds from an alcohol solution, and solid deposits upon small quartz plates were prepared with an Edwards high-vacuum coating unit. These samples were then sealed inside quartz cells through which it was possible to maintain a flow of dry oxygen or dry nitrogen (oxygen-free) continuously during exposure to a high-pressure mercury-vapour lamp (in glass) and while absorption measurements were being made on a Unicam SP 500 quartz spectrophotometer.
