stability the novel aqueous dispersion of this invention can be pigmented in the aforementioned pigment to binder ratio the pigments can be blended with the novel dispersion composition and then ground by conventional techniques such as sand milling pebble milling or ball milling to uniformly disperse the pigment in the composition preferably the pigment is formed into a mill base by grinding the pigment in either a dispersion of the polysulfone resin or a dispersion of another resin if one is used or a solution of one or both of any of the above resins the mill base is then blended with the coating composition the following are examples of the great variety of pigments which can be used in the coating composition of this invention metallic oxides preferably titanium dioxide zinc oxide and the like metal hydroxides metal flakes such as aluminum flake metal powders zinc powders sulfides sulfate carbonates carbon black silica silicates hydrophobic silicates such as silicone treated with silicone dioxide talc china clay iron oxide iron blues organic reds maroons and other organic dyes and lakes for high temperature use temperature resistant pigment such as carbon black or red iron oxide are used the novel dispersion of this invention can be applied to a variety of substrates for example metal glass or plastics by any of the usual application methods such as spraying electrostatic spraying dipping brushing flow coating roller coating.
