Abstract
This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to the discovery that incorporating a long-chain carboxylic acid of at least 50% by weight of the carboxylic acid component used to make polyester resins which are further incorporated into polyurethane resins provides basecoat composition exhibiting low temperature flash characteristics. These low temperature flash characteristics are exhibited even where the basecoat is deposited at 50-90% relative humidity.
