Title: Improvements in or relating to the manufacture or treatment of lacquers, varnishes, films, plastic masses or paints
IPC: C08K5/103

Abstract: Lacquers, films, paints, varnishes, or plastic masses containing nitrocellulose or other cellulose derivatives, comprise as solvent, gelatinizing, or softening agent one or more esters of high molecular polyhydric unsaturated aliphatic alcohols with organic or inorganic acids.  The ester may be of ricinoleic alcohol, grape seed alcohol, or of an alcohol obtained by hydration of linoleic alcohol or a hydrocarbon such as squalene. Formic, acetic, butyric, lactic, lauric, ricinoleic, abietic, naphthenic, benzoic, salicylic, anthranilic, succinic, tartaric, adipic, sebacic, citric, cyclohexane diacetic, phthalic, hydrophthalic, phosphoric, sulphuric, and boric acid are specified acid components of the esters.  These esters are solvents for resins including artificial resins such as polymerized vinyl compounds or oil soluble glycerol-phthalic acid resins, and they are solvents for india rubber, asphalt, dyestuffs particularly oil soluble tar dyestuffs, oils, waxes, and fats. These additional substances may thus be incorporated with the cellulose derivative compositions.  The diacetate of ricinoleic alcohol is specially mentioned in this respect.  In an example, a varnish comprises nitrocellulose, a polymerized vinyl resin, diacetate of ricinoleic alcohol, acetone, butanol, and butyl acetate.  A leather dressing comprises nitrocellulose, castor oil dilactate of ricinoleic alcohol, ethyl alcohol, cyclohexanone, butyl acetate, and toluene.  A lacquer comprises benzyl cellulose, dibenzoate of ricinoleic alcohol, toluene, and tetrahydronaphthalene.  The Specification as open to inspection under Sect. 91 comprises also the use of esters of high molecular polyhydric unsaturated aliphatic alcohols as solvents or softening agents in lacquers, films, pastes, paints, and plastic masses, without limitation to those containing cellulose derivatives, and in rubber compositions.  The esters are stated to be of use in the vulcanization of rubber since they facilitate the incorporation of other materials.  Resin, artificial resin, rubber, asphalt, dye stuffs, oils, and fats are specified ingredients of the varnishes, paints, films, or plastic masses.  In an example, a coating which may be applied to a foundation such as Japan tissue paper in the production of duplicating stencils comprises collodium, ditartrate of ricinoleic alcohol, esterification products of hydrated linoleic alcohol and acetic acid, benzene, acetone methyl alcohol and barium sulphate.  A coating which may be applied to paper and then hardened comprises gelatine, water, salicylic acid, ammonia, glycerine ester of adipic acid, ditartrate of grape stone alcohol, and bolus.  This subject-matter does not appear in the Specification as accepted.ALSO:Esters of high molecular polyhydric unsaturated aliphatic alcohols with organic or inorganic acids are employed as solvents for resins, including artificial resins such as polymerized vinyl compounds or oil soluble glycerol-phthalic acid resins, indiarubber, asphalt, dyestuffs particularly oil soluble tar dyestuffs, oils, waxes and fats.  The diacetate of ricinoleic alcohol is specially mentioned in this respect.  The ester may be of ricinoleic alcohol, grape seed alcohol, or of an alcohol obtained by hydration of linoleic alcohol or a hydrocarbon such as squalene.

The Specification as open to inspection under Sect. 91 comprises also the use of esters of high molecular polyhydric unsaturated aliphatic alcohols as solvents or softening agents in lacquers, films, pastes, paints, and plastic masses, other than those containing cellulose derivatives, and in rubber compositions. The esters are stated to be of use in the vulcanization of rubber since they facilitate the incorporation of other materials. Resin, artificial resin, rubber, asphalt, dyestuffs, oils and fats are specified ingredients of the varnishes, paints, films, or plastic masses.
