Abstract: Disclosed are a method of dispersing a pigment, a pigment dispersion, a coating composition comprising said pigment dispersion, an method of making a coating composition, and a method of improving the appearance of a coating composition. The pigment dispersion of the invention requires at least one pigment subjected to an action to decrease the average particle size of the pigment in the presence of an amine functional cellulose ester resin.

Abstract: Disclosed are amine functional cellulose ester resins and methods of making the same. The amine functional cellulose ester resins comprise at least one repeat unit of the structure: wherein R1, R2, and R3 are selected independently from the group consisting of hydrogen, R4C═O, and wherein at least one of R1, R2, and R3 is hydrogen, at least one of R1, R2, and R3 is R4C═O, and at least one of R1, R2, or R3 have the structure R4 is selected from the group consisting of C1-C20 alkyl groups, C1-C20 phenyl groups, C1-C20 napthyl groups, and C1-C20 alkenyl groups, L is a divalent linking group and R6 is selected from the group consisting of H and compounds having at least one secondary amine group, tertiary amine group, and mixtures thereof.

Abstract: Low VOC coating compositions are disclosed. In particular, high solids low volatile organic (VOC) solvent-borne automotive paint composition are disclosed. In addition, low VOC alkyd compositions are disclosed for use alone or that may also be used with conventional high VOC tinting bases. The compositions include a resin consisting of the esterification reaction product of dehydrated castor oil fatty acid, tris-hydroxyethyl isocyanate and hydrated monobutyl tin oxide and an ethyl acetoacetonate chelation reaction product with aluminum alkoxide.

Abstract: A non-isocyanate flexibilizer additive is provided which finds utility in coating systems such as alkyds, polyesters, acrylic/polyester, alkyd/acrylic, carboxy/epoxy, polyether/urethane, epoxy/polyester, other epoxy, and urea and melamine formaldehyde systems. The non-isocyanate functional flexibilizer has the formula; B--C(O)--NW--A--NX--C(O)--K wherein A is selected from the group consisting fundamentally of polyesters, polyamides, polyureas, polyurethanes, acrylics; biuret, allophonate and urethane extended polyesters; wherein B and K are selected from the group consisting of --OR and --Z--R'--SiOR".sub.(3-n) R"".sub.n wherein R' is a divalent lower alkyl radical of from 1 to 18 carbon atoms, R is a lower alkyl radical of from 1 to 18 carbon atoms, Z is a member selected from the group consisting of S and NR", W and X are selected from H and lower alkyl radicals of from 1 to 10 carbon atoms, wherein R", R" and R"" are H or a lower alkyl radical of from 1-18 carbon atoms, and wherein n is 0, 1 or 2.
