Abstract
PURPOSE: To provide a title composition allowing low-temperature baking and giving nonlifting, smooth coating layer excellent in clarity and boiling water resistance, which consists of a specific resinous product and a polycarboxylic cpd.
CONSTITUTION: A polyester (a) having an acid value of 1W40 is provided by reacting 100pts.wt. of a prepolyester with an acid value less than 20, in which a dibasic acid unit is occupied in 50mol% or more by a terephthalic acid unit and occupied in 50mol% or less by an isophthalic acid unit and/or a hexahydrophthalic acid unit, with 0.1W18pts.wt. of a polybasic acid not contg. polymerizable unsaturated gp. In the presence of 5W80wt% of the polyester (a), 10W50wt% of a vinyl monomer (b) contg. one or more glycidyl gps in molecule, 10W70wt% of a styrene monomer (c), and 0W50wt% of another vinyl monomer (d) are polymerized to a resinuous product (A). To one eq. of glycidyl gp. in the product (A), 0.5W2eqs. of a polycarboxylic cpd. (B), such as sebacic acid or phthalic anhydride, is compounded.
