Abstract

292,894. Johnson, J. Y., (I. G. Farben. industrie Akt.-Ges.). March 16, 1927. Divided on 292,655, [Class 146 (iii), Writing-instruments &c.]. Printing-surfaces ; blankets.-Hectograph compositions, inking rollers, and printers' blankets are prepared by incorporating sorbitol, its dehydration products obtained by the application of heat with or without the use of dehydrating agents, or derivatives thereof such as acetyl sorbitol, with the materials usually employed such as gelatine, glue, or the like, and resins, oils, fats, or waxes. The viscosity is determined by the amount of water used, thickeners such as starch being dispensed with. Glycol, glycerine, acetin, and dextrin may also be added. Accord. ing to examples, use is made of an aqueous solution of gelatine and sorbitol, and a solution of gelatine and dehydrated sorbitol in water and glycol.
