| titleOfInvention | Liquid coating compositions |
| abstract | A liquid coating composition is prepared by mixing a clear dispersion of a fatty acid-treated colloidal hydrous iron oxide pigment in a volatile organic liquid with a clear solution of a polymer of methyl methacrylate having a relative viscosity of 1,117-1,196 (measured as a 0,5% solution in ethylene dichloride at 25 DEG C.) the weight of the polymer being at least equal to the weight of the pigment and, based on the total weight of the total fluid mix, the pigment constituting up to 15% and non-volatile solids constituting up to 35%, to provide a clear fluid mixture which, as freshly prepared, yields a cloudy film when applied as a coating and dried, and then ripening the mixture whereby it yields a clear film when applied as a coating and dried. Methylmethacrylate polymers specified are the monopolymers and copolymers with minor amounts of other monomers such as acrylic and methacrylic acids, methyl acrylate, C2-C4 alkyl acrylates and methacrylates, glycidyl methacrylate and styrene, and mixtures of such polymers. The iron oxide pigments used are those obtained by treating colloidal hydrous iron oxide with fatty acids such as caprylic, lauric, myristic, palmitic and naphthenic acids and castor oil, tall oil and coconut oil acids. The solution of the polymer and dispersion of the pigment are made with the aid of solvents such as benzene, toluene, xylene, acetone, methyl ethyl ketone, ethyl acetate and ethylene glycol monoethyl ether. Other specified ingredients are amine-treated bentonite, aluminium paste, phthalocyanine green, nitrocellulose and benzyl butyl phthalate. The ripening of the compositions can be effected by storing at room temperature, but it is hastened by agitation and/or warming to a moderately elevated temperature. Specifications 499,790 and 807,895 are referred to.ALSO:A fatty acid-treated colloidal hydrous iron oxide pigment is prepared from a slurry of hydrous iron oxide in water by adding thereto a solution of coconut oil acids in xylene, and heating at 50-60 DEG C. with agitation for 1 hour. Water is removed from the mixture leaving a clear dispersion of the treated iron oxide in xylene. Specifications 499,790 and 807,895 are referred to. |
