Abstract

PURPOSE: To provide a coating composition excellent in hardness, flexibility, water resistance and corrosion resistance, comprising by mixing an oil-free alkyd resin obtained by using a polyphenolic carboxylic acid as one component of a starting material with an amino resin.
CONSTITUTION: (i) A polyphenolic carboxylic acid, e.g., 2,3-dihydroxybenzoic acid, gallic acid, (ii) a polybasic carboxylic acid, (iii) a polyhydric alcohol and, according to necessity, (iv) a monobasic carboxylic acid are subjected to esterification reaction according to a conventional method by using a component (i) in an amount of 1W15wt% based on a total amount of all components to obtain an oil- free alkyd resin with an acid value of 50KOHmg/g or less and a hydroxyl value of 50W250KOHmg/g, 50W95pts.wt. of this alkyd resin (A) and 5W50pts.wt. of an amino resin (B) are mixed by a sand mill or the like to obtain the titled composition. This composition is painted on a steel plate or the like by a brush painting or an immersion painting method and, by heating and drying a paint coating at 100W200°C, a cured paint coating is formed.
USE: This composition is suitable for painting a steel plate or a nonferrous metal (Al plate).
