COATING COMPOSITION CONTAINING AUTOXIDIZABLE ALKYD RESIN AND COMPOSITION OF DRIER Russian patent published in 2018 - IPC C08K5/00 C08K5/98 C09D167/08 C09F9/00 C09D11/105 

FIELD: chemistry.

SUBSTANCE: invention relates to a coating composition comprising a self-oxidizing alkyd resin and a desiccant composition. Desiccant composition comprises: a) an iron-ligand complex containing iron and at least one bispidine ligand; and b) a vanadium compound. Amount of the vanadium compound in the desiccant is such that the coating composition contains vanadium in a concentration in the range of from 0.01 to 1.0 % by weight. based on the weight of the solid alkyd resin. Amount of the iron-ligand complex in the desiccant is such that the coating composition contains iron in a concentration in the range of 0.5×10^-4 up to 5×10^-3 wt.% based on the weight of the solid alkyd resin.

EFFECT: invention provides coatings that dry out over a short period of time, with a low tendency to yellowing, with good initial and final hardness.
