Title: Improved manufacture of coloured or pigmented cellulose derivatives and products having a cellulosic base
IPC: D06P1/44
Filed: 1927-09-22
Abstract: 277,989. Stubner, E. C. de. June 7, 1927. [Convention date]. Incorporating paint ingredients.-Soluble cellnlose derivatives of cellular structure, such as nitrocellulose, for use in the manufacture of lacquers, enamels. &c., are pigmented or coloured by treatment with a colloidal solution of a pigment or colouring matter in such a manner that the pigment is deposited on the derivative. Thus. the cellulose derivative is steeped in a colloidal solution or suspension of the pigment and a precipitant added to deposit the pigment. Alternatively, the cellulose derivative may be first treated so as to cause the pigment to deposit thereon; for example, aluminium hydrate is first precipitated on the derivative, which is then treated with a colloidal solution of ultramarine, the deposition of the hydrate giving on the negatively-charged derivative a positively-charged surface capable of adsorbing the negatively-charged ultramarine; by depositing other hydrates, such as those of iron, copper or cadmium, the cellulose derivative is made capable of adsorbing the sulphides of antimony, lead, and zinc; in the case of colloidal metals such as silver, gold or platinum the necessary change of electrical sign is obtained by the addition of titanic acid, albumen or agar. Pigments that mav be so applied are :-lamp black, carbon black, bone black, zinc oxide, lithopone, white lead, ultramarine, vermilion, prussian blue, zinc yellow, lead chromates, chromium oxides, red lead, and lakes. The pigmented cellulose derivative after separation from the water or other liquid used for the preparation of the colloidal solution of the pigment, may he used directly for the manufacture of lacquer &c., or it may be dehydrated as described in Specification 277,949. Specification 211,178, [Class 1 (ii), Chemical processes &c.], also is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to pigmentation with sulphur and vat colours and acid dyes. This subject-matter does not appear in the Specification as accepted.
