摘要:
This invention is directed to water-dilutable alkyd and acrylate resins. More particularly, this invention is directed to a method for the preparation of water-dilutable resin preparations based upon alkyd and acrylate resins which comprises the steps of:(a) preparing an aqueous alkyd resin dispersion, wherein the alkyd resin has an acid number of from about 5 to 40 and a hydroxyl number of from about 150 to 300 and the dispersion has a solids content of from about 30 to 90 percent by weight; and(b) polymerizing monomers of acrylic acid derivatives or methacrylic acid derivatives in the dispersion from step (a), optionally in the presence of additional water, to obtain a total solids content of from about 30 to 80 percent by weight, the weight ratio of alkyd resin to acrylate resin being from about 1:4 to 9:1.This invention is also directed to the use of these binders in water-dilutable lacquer systems.
