prepared by refluxing together in pyridine containing triethylamine 2 - (b - acetanilidovinyl) - 5 : 6 - methylenedioxybenzselenazole ethiodide and 2-methyl-5 : 6-dimethylbenzthiazole ethyl p - toluenesulphonate, and adding aqueous potassium iodide to an alcohol solution of the precipitated dye...
(Ph. Eur. method 2.2.2)♢ A solution is colourless if it has the appearance of water R or the solvent used for the preparation of the solution to be examined, oris not more intensely coloured than reference solution B 9 .Report the results together with the method used (method I, me...
13. The colour laser markable document according to any one of claims 9 to 12 wherein the colour laser markable document contains on the same side of the opaque white core support as the colour forming layer at least one second colour forming layer capable of forming a different colour. 14....
Alternatively, it may contain silver chloride or bromide mixed with excess of potassium iodide. The images in the layers may be copied successively onto double-coated film or simultaneously onto separate films, e.g. as shown in Fig. 3 in which the images on the film 10 illuminated by the ...
Potassium iodideColourThis study evaluated whether the presence of the salivary acquired pellicle (AP) had any effect on the dentin's darkening and on the caries arresting effect after the use of SDF+KI, in a cariogenic challenge.#Human dentin specimens were standardised, submitted to artificial ...
A further variation consists in exposing to a red-record positive, and developing in a bath of potassium ferrocyanide. A filter dye less fugitive than tartrazine, e.g. Brilliant Yellow, may be used in the emulsion layer if this is thin, so that the dye is not completely eliminated in the...
A new supersensitive spectrophotometric method for the determination of tellurium (IV) has been developed which is based on the formation of an ion-association complex with potassium iodide and rhodamine B (RhB) in the presence of polyvinyl alcohol (PVA) and polyethylene glycol octyl phenyl ether ...
In the present process the positive printed from the negative of violet-blue sensation is coloured yellow by means of a solution of auramine in the presence of basic aluminium acetate. The positive, after printing, is treated with a solution of potassium ferricyanide, potassium iodide, and ...
It is printed from the blue record and the latent image developed in a solution comprising sodium sulphite, metol, hydroquinone, sodium carbonate, potassium bromide and water and toned in a bath containing potassium iodide and iodine to a yellow image of silver iodide. This image is dyed with...
