FIELD: chemistry.
SUBSTANCE: invention relates to a coating composition comprising an oxidatively curable alkyd resin and a complex compound of a chelating agent of formula (I):
(I),
in which: each R is independently selected from C1-C24 alkyl; Q is a C2-C6 alkylene bridge; and each R1, R2, R3 and R4 is a hydrogen atom; and a manganese ion, wherein the complex compound is not defined. Process for the preparation of said composition, a coating composition obtained as a result of its curing, and a kit for producing a coating composition comprising a chelating agent of formula (I) and a method for coating a substrate of the above composition are also disclosed.
EFFECT: obtaining fast curing coating compositions by using unidentified manganese complex compounds including ligands based on bis-triazacyclonone of formula (I), which were found to be much more active with respect to oxidative curing reactions.
