  • Patent number: 5162399
    Abstract: Disclosed is a process for preparing ink millbase by use of a polymer blend of compatible polyesters and acrylic polymers. The polyesters are water-dispersible as a result of sulfonate groups on the polyester backbone. Use of the polymer blend results in an improvement in pigment particle size reduction during grinding.

  • Patent number: RE34730
    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.
