Abstract

PURPOSE:To prevent segregation and improve storage stability, gloss, pigment dispersion and atomization in spraying by compounding a specific acrylic water- soluble resin and an alkyd resin. CONSTITUTION:A copolymer is obtained by copolymerizing 30-60wt.% (hereinafter abbreviated to %) methyl methacrylate, 10-30% styrene, 10-40% 4-18C (meth)acrylate, 3-10% OH-containing (meth)acrylate, 3-10% ethylenically unsaturated carboxylic acid, and 0-20% other copolymerizable monomers. The copolymer is neutralized with a volatile basic material in an amount with which 60-150% of the COOH groups of the copolymer are neutralized, and then diluted with water to obtain an acrylic water-soluble resin having a number-average molecular weight of 5,000-20,000, a glass transition temperature of 30-60 deg.C and an SP value of 9.5-10.5. The obtained resin is blended with 2-20% alkyd resin to obtain the title composition.
