Abstract
PURPOSE: To prepare the title composition having excellent workability, and giving a coating film having excellent apperance without causing skimming and sagging, by polymerizing a specific acrylic monomer in a solution comprising a specific acrylic polymer dissolved in a water-miscible solvent, and partly neutralizing the resulting polymer with an amine.
CONSTITUTION: An acrylic polymer having an acid value of 15W40, a hydroxyl value of 25W100 and a number average molecular weight of ≥8,000 is prepared by polymerizing a monomer selected from (a) an unsaturated carboxylic acid, (b) a (meth)acrylic acid ester, and (c) a vinyl monomer copolymerizable with the component (a) or (b), in a solution prepared by dissolving (A) a polymer having an acid value of 50W150, a hydroxyl value of 25W100 and a number average molecular weight of 4,000W10,000 and obtained by polymerizing a monomer of (a) to (c), in (B) a solvent which is miscible with water. The polymer thus obtaied is neutralized by adding an amine in an amount necessary to neutralize more than 20% of the total acid equivalent of the polymer, and then adding water thereto. The weight ratio of the polymer in the solution to the polymer obtained is 20/80W60/40, and the amount of water in the water-miscible solvent is 50W90wt%.
