1. In an article having a substrate and a multilayer coating composition adhered thereto, said composition comprising:
- A. a dried nonaqueous base film produced from a composition comprising;
1. a first film-forming material selected from the group consisting of alkyd resins, polyester resins, acrylic resins, and polyurethane resins, wherein said first film-forming material contains from about 2 to about 50 weight percent, based on the film-forming solids, of a cellulose ester,2. uniformly dispersed pigments, and3. volatile organic solvents for said first film-forming material, andB. a baked transparent coating composition deposited on said base film in a relationship to maintain substantially no intermixing and no intersolution of said base film and said transparent coating composition, said transparent coating composition comprising;
1. a second film-forming material selected from the group consisting of alkyd resins, polyester resins, acrylic resins and polyurethane resins, and2. volatile organic solvents for said second film-forming material, the improvement comprising;
said second film-forming material consisting essentially of polyester resins comprising a crosslinking resin containing hydroxyl groups obtained by esterifying polycarboxylic acids selected from the group consisting of aliphatic polycarboxylic acids, cycloaliphatic polycarboxylic acids, and mixtures thereof with polyols selected from the group consisting of aliphatic polyols, cycloaliphatic polyols and mixtures thereof.

Abstract
An article having a substrate and a multilayer coating composition adhered thereto. The multilayer coating has a pigmented base film and deposited on the base film is a transparent coating which has no intermixing and no intersolution between the base coating and the transparent coating. The transparent coating is a cross linking resin containing hydroxyl groups obtained by esterifying polycarboxylic acids with polyols.

13. In a process for preparing an article having a substrate and a multilayer coating composition adhered thereto, comprising:
-
A. depositing a nonaqueous base film with drying a composition comprising; 1. a first film-forming material selected from the group consisting of alkyd resins, polyester resins, acrylic resins, and polyurethane resins, wherein said first film-forming material contains from about 2 to about 50 weight percent, based on the film-forming solids, of a cellulose ester, 2. uniformly dispersed pigments, and 3. volatile organic solvents for said first film-forming material, and B. depositing with baking a transparent coating composition on said base film in a relationship to maintain substantially no intermixing and no intersolution of said base film and said transparent coating composition, said transparent coating composition comprising; 1. a second film-forming material selected from the group consisting of alkyd resins, polyester resins, acrylic resins and polyurethane resins, and 2. volatile organic solvents for said second film-forming material, the improvement comprising;
said second film-forming material consisting essentially of polyester resins comprising a crosslinking resin containing hydroxyl groups and obtained by esterifying polycarboxylic acids selected from the group consisting of aliphatic polycarboxylic acids, cycloaliphatic polycarboxylic acids and mixtures thereof with polyols selected from the group consisting of aliphatic polyols, cycloaliphatic polyols and mixtures thereof. - View Dependent Claims (14)
