Title: Drier composition
IPC: C07D487/04

Abstract: Film-forming compositions containing drying or semi-drying oils comprise, as drying accelerators, substances of the general formul <FORM:0822365/III/1> <FORM:0822365/III/2> and <FORM:0822365/III/3> where X and Y are hydrogen, halogen, hydroxy, nitro, carboxy, or aliphatic or aromatic organic radicals, and R and Z represent the atomic groupings necessary to form a fused carbocyclic, aromatic or heterocyclic ring on the diazine nucleus.  X and Y may be alkyl, alkoxy, hydroxyalkyl, haloalkyl, carbalkoxy, acylamino, dialkylamino, aryl, haloaryl, nitroaryl, oxyaryl, arylsulphonyl, arylsulphonamido, acyl, or heterocyclic, e.g. furyl, thienyl, pyrryl, quinolyl, diazinyl, oxazinyl and the like.  The fused nuclei resulting from substitution of R and Z include the ring structures of benzene, naphthalene, anthracene, acenaphthene, chrysene, perylene, pyrene, phenanthrene and the like and derivatives thereof such as alkyl, alkoxy, hydroxyalkyl, halogen, nitro, carboxy, carbalkoxy, acyl, acylamino or sulphonamido-substituted derivatives.  Heterocyclic structures resulting from fusion of groups R and Z are similar to those radicals which are suitable for X and Y.  Many specific examples of suitable compounds are given.  Suitable film-forming materials include drying and semi-drying oils, or drying or semi-drying oil-modified resins such as alkyd resins, coumarone-indene resins, phenolic resins, ester gums, modified rosins and natural resins. In examples of compositions using such compounds as driers or as drier accelerators in conjunction with metallic driers, the film-forming agent may be an oil-modified alkyd resin, a rosin-modified phenol resin plus tung oil and linseed oil, linseed oil, or dehydrated castor oil, and drying agents specfied are dibenzophenazine, acenaphthoquinoxaline, indoloquinoxaline, 2 : 3-diphenylquinoxaline, the compound <FORM:0822365/III/4> 7-methoxy-5-p-tolyl sulphonamido-quinoxaline, benzo-furo quinoxaline, 7-chloro-pyrido-pyrazine, 2 : 3-quinoxaline dicarboxylic dimethyl ester, 2 : 3 - dimethyl - 6 - acetyl - quinoxaline, and 1 - methoxy - phenazine.  The compositions may also contain fillers, pigments, extenders, resins, thinners, plasticisers, and similar modifiers.ALSO:Film-forming compositions containing drying or semi-drying oils comprise, as drying accelerators substances of the general formul  <FORM:0822365/IV (a)/1> where X and Y are hydrogen, halogen, hydroxy, nitro, carboxy, or aliphatic or aromatic organic radicals, and R and Z represent the atomic groupings necessary to form a fused carbocyclic, aromatic or heterocyclic ring on the diazine nucleus.

The compositions may also contain fillers, pigments, extenders, resins, thinners, plasticisers, and similar modifiers.
