OXIDATIVELY CURABLE COATING COMPOSITION Russian patent published in 2018 - IPC C09D167/00 

FIELD: chemistry.

SUBSTANCE: invention relates to an oxidatively cured coating composition. Composition comprises an alkyd resin cured by oxidation and a chelating agent of formula in which each of the R¹, R², R³ and R⁴ is independently H, C₁-C₂₄ alkyl, C₆-C₁₀ aryl, or a group comprising a heteroatom capable of coordinating a metal ion; Q is methylene or ethylene in which one or more hydrogen atoms can be optionally independently substituted with C₁-C₂₄ alkyl or C₆-C₁₀ aryl; and Q' is ethylene or n-propylene in which one or more hydrogen atoms can be optionally independently substituted with C₁-C₂₄ alkyl or C₆-C₁₀ aryl. Chelating agent can optionally form a complex compound with a transition metal ion. Invention also describes methods for preparing such compositions and compositions obtained by curing such compositions.

EFFECT: accelerated curing of coating compositions.
