COMPOSITION PREVENTING FORMATION OF SURFACE FILM Russian patent published in 2016 - IPC C09D7/04 C09D167/08 

FIELD: chemistry.

SUBSTANCE: invention relates to paints, dyes and other coating compositions, particularly to alkyd-based compositions, containing metal driers, such as iron and manganese-containing compounds which exhibit low susceptibility to formation of a surface film during storage. Invention relates to a method which involves bringing an oxidation-curable alkyd-based coating composition containing an organic solvent as solvent into contact with an aqueous solution containing a complex of Fe or Mn with accelerating polydentate nitrogen-containing ligand of formula (I):

where each R is independently selected from hydrogen F, Cl, Br, hydroxyl, C₁-C₄-alkyl-o-, -NH-CO-H, -NH-CO-C₁-C₄-alkyl, -NH₂, -NH-C₁-C₄-alkyl C₁-C₄-alkyl; R1 and R2 are independently selected from C₁-C₂₄-alkyl C₆-C₁₀-aryl and a group consisting of one or two heteroatoms, able to coordinate with Fe or Mn; R3 and R4 are independently selected from hydrogen, C₁-C₈-alkyl, C₁-C₈-alkyl-O-C₁-C₈-alkyl, C₁-C₈-alkyl-O-C₆-C₁₀-aryl, C₆-C₁₀-aryl, C₁-C₈-hydroxyalkyl and - (CH₂)_nC(C)OR5, where R5 is independently selected from hydrogen, C₁-C₄-alkyl, n has values from 0 to 4 and X is selected from C=O, -[C(R6)₂]_y-, where y is from 0 to 3 and each R6 is independently selected from hydrogen, hydroxyl, C₁-C₄-alkoxy C₁-C₄-alkyl.

EFFECT: compounds which exhibit low susceptibility to formation of surface film during storage.
