Abstract: A preservative agent for cellulosic materials, particularly those used in building, such as wood, straw, &c., consists of a mixture of a fluoride or sulphate of copper or zinc with a phenol other than a nitro phenol or phenol-sulphonic acid, or with a naphthol.  The composition is particularly applicable to building slabs and blocks made from straw or reeds, for example, the material known under the registered Trade Mark "Solomite."  The composition prevents the growth of bacteria and fungi, and also protects the material from attack by rats and other rodents.  In an example zinc sulphate is dissolved in excess of alkali, and carbolic acid is added. Specification 290,827, [Class 87 (i), Bricks &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes compositions consisting of a substance exerting an anticryptogamic action, and any phenol or naphthol.  As anticryptogamic substances, fluorides, sulphates or other salts of copper, zinc, &c. are referred to.  The following are given as examples; the sodium salt of dinitro-naphthol, and tricresol; dinitro-ortho-cresol and ortho-cresol or tricresol; zinc sulphate and carbolic acid; and resorcin and sodium fluoride.  It is also stated that naphthol, b -naphthol, or a polybromic naphthol may be used alone.  This subject-matter does not appear in the Specification as accepted.
