| abstract | 702,614. Photographic emulsions. MEYERSTEIN, W. Oct. 21, 1952 [Sept. 20, 1951; Nov. 20, 1951], Nos. 22071/51 and 27169/51. Class 98(2) Blood is used as the light-sensitive substance in a photographic emulsion. Such an emulsion may have the following composition:-blood 4-8 cc., water 100 cc., sodium chloride 0.9 g, agar-agar 2 g (or alternatively gelatine 10 g). A dye such as eosin or methlene blue may be added. The emulsion my be applied to a glass plate, a film, or a sheet of paper or metal. Development is effected, without reversal, by leaving the exposed emulsion for 24 hours in darkness, and is then arrested by treatment with methyl alcohol or a 10 per cent solution comprising 25 cc. of 40 per cent formaldehyde, 0.9 g of sodium chloride and 75 cc. water. If the exposure time is prolonged excessively the image is reversed. Further, if the final drying after arrestment of development is effected slowly, local swellings occur and a relief image is obtained. |
