Patent ID: 8013044

Claim:
A curable liquid medium comprising: a) from 1 to 90 wt % of an alkyd-based resin; and, b) from 0.0001 to 0.1 wt % of a siccative, wherein the siccative is an iron or manganese complex of a tetradentate, pentadentate or hexadentate nitrogen donor ligand, wherein the ligand is: wherein each R is independently selected from: hydrogen, F, Cl, Br, hydroxyl, C1-C4-alkylO—, —NH—CO—H, —NH—CO—C1-C4-alkyl, —NH2, —NH—C1-C4-alkyl, and C1-C4-alkyl; R1 and R2 are independently selected from: C1-C24-alkyl, C6-C10-aryl, and, a group containing a heteroatom capable of coordinating to a transition metal; 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) n C(O)OR5 wherein R5 is independently selected from: hydrogen, C1-C4-alkyl, n is from 0 to 4, and mixtures thereof; and, X is selected from C═O, —[C(R6) 2 ] y - wherein Y is from 0 to 3 each R6 is independently selected from hydrogen, hydroxyl, C1-C4-alkoxy and C1-C4-alkyl.
