Abstract: Select metal salts of mono and di aromatic sulfonic acids and aliphatic sulfonic acids are effective latent acid catalysts in coating compositions capable of acid catalyzed crosslinking and provide coating compositions with lower cure temperature and quicker cure times than encountered with conventional sulfonic acid catalysts, have excellent storage stability and avoid drawbacks of epoxy and amine blocked sulfonic acid catalysts.

Abstract: A golf ball having a coating of a water-based, water-reducible polyurethane, and a related method of forming a coating on a golf ball which avoids the problems of foaming of the coating. The coating is formed by the addition of a first component comprising a compound having hydroxyl functionality, an organic solvent, an optical brightener and water, to a second component comprising an aliphatic polyisocyanate and an organic solvent. In addition, a method of forming a top coat on a golf ball having a SURLYN.RTM. outer layer which avoids the use of a primer coat or adhesion promoting layer is disclosed.
