Abstract

818,937. Electrolytic recording paper. MUIRHEAD & CO. Ltd. Aug. 21, 1957 [Dec. 20, 1956], No. 38856/56. Addition to 786,496. Class 96. [Also in Group XL (b)] The electrolytic recording medium for facsimile and phototelegraphic receivers of the parent Specification contains efflorescent sodium sulphate in addition to the polyhydroxyphenolic compound, oxidant and electrolyte. Examples of aqueous impregnating solutions are, in parts by weight, 10 parts sodium sulphate decahydrate, 7.5 parts sodium chlorate, 4.5 parts sodium nitrate, 3.5 parts catechol and minor amounts of citric acid and thiourea; and, where the sodium sulphate is used as both the electrolyte and the agent for promoting drying, 8.6 parts each of sodium sulphate decahydrate and. sodium chlorate, 3.5 parts catechol and minor amounts of citric acid and thiourea.
