Abstract
Disclosed are aromatic enol ethers that have utility as film-hardening additives for coating formulations. The aromatic enol ethers have particular utility as film-hardening additives for water-based coating formulations. The aromatic enol ethers provide improvements in hardness and hardness related properties such as block resistance without contributing to the volatile organic content of the composition.
