ABSTRACT OF THE DISCLOSURE An aqueous dispersion having a pH of about 7 to about 10.5 and comprising (A) a specific urethane diamine having a molecular weight of about 5,500 to about 25,000, (B) about 0.5 to about 20 parts by weight, per 100 parts by weight of the urethane diamine (A), of a polyoxy- ethylene ether as an emulsifier having a hydrophilic-lipophilic balance (HLB) of about 11 to about 16 and selected from the group consisting of polyoxyethylene aryl ethers and poly- oxyethylene lauryl ether, (C) about 50 to about 300 parts by weight, per 100 parts by weight of the urethane diamine (A), of water, (D) an acid as a pH adjusting agent in an amount sufficient to adjust the pH of the aqueous dispersion to about 7 to about 10.5, and (E) a filler in an amount which is within the range of 0 to about 300 parts by w?ight per 100 parts by weight of the urethane diamine (A) and which does not cause phase separation of the aqueous dispersion. An aqueous coating composition which will give coatings of high adhesion strength and good weatherability can be prepared from the aqueous urethane diamine dispersion and an aqueous dispersion of a diepoxy compound.
