Abstract: An essentially linear polyester oligomer having hydroxyl and carboxyl terminal groups for subsequent cure and its production are disclosed. This polyester oligomer is produced by first adducting approximately equimolar amounts of diol carrying two primary hydroxyl groups and a dicarboxylic acid anhydride to form an hydroxy acid.

This hydroxyl-terminated oligomer is then adducted with a polycarboxylic acid monoanhydride having a carboxyl functionality of at least 3, this monoanhydride being used in an amount of 0.01 to 0.15 equivalents of anhydride per hydroxyl equivalent in the hydroxyl-terminated oligomer.

Abstract: Pigmented coating solutions are disclosed which deposit coatings possessing improved resistance to ultraviolet radiation-induced auto-oxidation. These solutions contain organic solvent, including aromatic hydrocarbon solvent, having dissolved therein an aromatic hydrocarbon-soluble, normally liquid, polysulfide or polydisulfide derivative having terminal -SH groups which have been reacted with a monofunctional reactant providing a C.sub.1 -C.sub.22 alkyl terminal group to provide an essentially nonreactive derivative.
