Abstract
Coating compositions comprise: a curable compound comprising: a core chosen from a C6 carbocyclic aromatic ring, a C2-5 heterocyclic aromatic ring, a C9-30 fused carbocyclic aromatic ring system, a C4-30 fused heterocyclic aromatic ring system, C1-20 aliphatic, and C3-20 cycloaliphatic, and three or more substituents of formula (1) wherein at least two substituents of formula (1) are attached to the aromatic core; provided that no substituents of formula (1) are in an ortho position to each other on the same aromatic ring of the core; a polymer; and one or more solvents, wherein the total solvent content is from 50 to 99 wt % based on the coating composition.
