    Abstract: A coating composition is formed from an acid-set coating varnish and a pigment composition. The pigment composition includes a specific organic dyestuff derivative and a specific basic-group-containing resin-type pigment dispersant. The coating composition excels in pigment dispersibility, nonflocculation properties, noncrystallizability and fluidity. When used as a coating, the coating composition has excellent color tone, gloss, hardness, weather resistance, and solvent resistance.

    Abstract: An aqueous based coating composition contains a polymeric film-forming resin and as an additive from about 1 to about 40 percent by weight based on the resin solids of the composition of an oligomeric ester having an acid value of from about 100 to about 500 of the structure: ##STR1## where X is the residue of a polyol containing from 1 to 50 carbon atoms per hydroxyl group after reaction with an acid or an anhydride, R is an organic moiety from the acid or anhydride and A has an average value of about 2 or greater.The coating compositions are particularly advantageous as metallic pigmented coating compositions for automotive basecoat applications because they exhibit excellent resistance to mottling, have good flop and have reduced sensitivity to fluctuations in relative humidity.

    Abstract: The present invention provides for amino-crosslinkable coating formulations based on a mixture of a di or polyhydroxy functional polymeric component selected from the group consisting of diesters, polyesters, alkyd polymers, acrylic polymers and polycarbonate polymers, a methylol (alkoxymethyl) amino crosslinking agent and a bis-aromatic polyhydric phenol component having the structure of formula I: ##STR1## wherein X is selected from the group consisting of carbon to carbon covalent bond, oxygen, sulfur, --S--S--, --CO--, --SO--, --SO.sub.2 -- and a divalent organic radical having a molecular weight less than about 400, and wherein Y is independently selected from the group consisting of hydrogen, halogen, C.sub.1 to C.sub.4 alkyl and C.sub.1 to C.sub.4 alkoxy.The crosslinkable compositions of this invention may be used to prepare curable coating and paint formulations, and also may contain other ingredients such as a crosslinking catalyst, fillers, pigments and the like. When cured, the coatings of this invention exhibit improved hardness properties when compared with cured coatings which do not contain the aromatic polyhydric phenol additive. The presence of the additive also serves to eliminate the problem of coating softening when the coated substrate is baked for a prolonged period of time. These cured coatings also have good weatherability, good corrosion resistance and hydrolytic stability, enhanced oxidative and radiation stability, good solvent resistance and good adhesion properties.
