Title: Improvements in or relating to the manufacture of varnishes, lacquers, or putty masses
IPC: C09D191/00
Filed: 1932-07-04
Abstract: As constituents of oil lacquers or varnishes or putty compositions, use is made of esters of fatty acids containing not more than six carbon atoms in the molecule with alcohols corresponding to soap-forming carboxylic acids.  Specified alcohols from which the esters may be prepared are those corresponding to cocoanut oil acids, naphthenic acids, and resin p  acids, and also oleic, cetyl, myristic and lauryl alcohols.  Free alcohols corresponding to soap-forming carboxylic acids may also be included in the products.  In the examples, (1) a lacquer is prepared from linseed oil, cetyl acetate, oleic alcohol, varnish benzine, and a pigment; (2) a putty composition is prepared from linseed oil varnish, turpentine oil, cetyl acetate, myristic alcohol, slate dust, and white lead. Reference is made to the inclusion in the lacquers of copal resin and like substances, and siccatives such as cobalt naphthenate. Specification 375,002 is referred to.  The Specification as open to inspection under Sect. 91 describes the use of the esters specified above as constituents of lacquers or varnishes in general.  It also describes the use, as constituents of lacquers or varnishes or putty compositions, of esters of the specified alcohols with soap-forming carboxylic acids such as resin acids or the acids of linseed oil or sunflower oil.  It states also that the alcohols may be used as alternatives to their esters.  The following examples are given: (1) a lacquer is prepared from asphalt, oleic alcohol, wood oil, cobalt linoleate, and a diluent such as varnish benzine; (2) colophony and wood oil are heated to 300 DEG  C. with alcohols obtained by reducing palm-kernel oil acids, and the product is mixed with cobalt naphthenate and a diluent to produce a lacquer; (3) a lacquer is prepared by heating dammar resin and linseed oil with myristic alcohol, and diluting the product, e.g. with a mixture containing benzene homologues; (4) linseed oil is heated with alcohols obtained by reducing naphthenic acids or cocoanut oil acids, and the product is mixed with copal and lead-manganese oleate to produce a varnish. This subject-matter does not appear in the Specification as accepted.ALSO:As constituents of putty compositions, use is made of esters of fatty acids containing not more than six carbon atoms in the molecule with alcohols corresponding to soap-forming carboxylic acids.
