Abstract: Blends of low molecular weight hydroxy-terminated polyesters, based on diols, such as 2,2,4-trimethyl-1,3-pentane diol, and diacids or their esters, such as isophthalic acid, and methyl esters of short chain aliphatic diacids, are provided. The blends can be crosslinked with conventional crosslinking agents such as nitrogen resins or polyisocyanates. The formulated coatings have high solids content of relatively low viscosities and are useful on e.g. metallic substrates forming, upon curing, coatings having excellent tensile strength, hardness, and resistance to staining, weathering, and corrosive conditions.

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. The solvent also has dissolved therein a polar polymeric binder (preferably thermosetting) which degrades by a photo-oxidative mechanism and which has only limited compatibility with the derivative. The pigment protects the bulk of a deposited coating, and the limited compatibility causes a heated film of the coating solution to stratify as the solvent evaporates to concentrate the derivative at the surface of the cured coating to protect the same.
