Patent number: 5510148Abstract: A method of forming a multilayer coating on a substrate utilizes a pigmented aqueous based coating composition. The 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.Type: GrantFiled: May 2, 1994Date of Patent: April 23, 1996Assignee: PPG Industries, Inc.Inventors: Dennis Taljan, James E.

Patent number: 5215811Abstract: A protective and decorative polymeric sheet material for bonding to substrates by thermoforming comprises a flexible carrier film, a paint layer on one surface of the carrier film containing a colorant or light reflective flakes or both; and a transparent topcoat overlying the paint layer. At least a portion of the transparent topcoat is a rubbery cushioning layer formed of a non-crosslinked, or lightly crosslinked polymeric composition of low Tg.The sheet material has an unextended state and is heat softenable to a plastic state in which it is extendable to an extended state at least 50% greater in area than the unextended state. The paint and topcoat layers have substantially uniform quality and appearance in both the unextended and extended states. In a preferred embodiment, the thickness of the transparent topcoat is at least 0.1 millimeter. The thick topcoat provides improved retention of gloss and distinctness of image when the sheet material is stretched.Type: GrantFiled: December 20, 1990Date of Patent: June 1, 1993Assignee: Eastman Kodak CompanyInventors: Gerald G.
