Abstract
PURPOSE: The titled composition, capable of giving a film having improved corrosion resistance, weather resistance and surface smoothness, and prepared by incorporating (reacting) a polyfunctional epoxy compound with a polyester resin having a carboxyl group and a specific copolymer having a carboxyl group.
CONSTITUTION: A composition prepared by incorporating (A) a polyester resin having a carboxyl group, a number-average molecular weight of 800W5,000, a softening point of 50W150°C and an acid value of 10W150 with (B) a copolymer having a number-average molecular weight of 2,000W50,000 and a softening point of 50W150°C obtained by copolymerizing (i) 2W30wt% an α,β-unsaturated carboxylic acid, e.g. acrylic acid, with (ii) 98W70wt% another copolymerizable ethylenically unsaturated compound, e.g. styrene, and (C) a polyfunctional epoxy compound at a weight ratio between (A) and (B) of 95:5W5:95 and an equivalent ratio between the epoxy group in the constituent (C) and the total COOH group in the constituents (A) and (B) of 0.2:1W3:1. Alternatively, the constituents (C) and (A) and/or the constituent (B) are partly reacted and incorporated.
