ABSTRACT:
The invention provides aqueous multicolor compositions containing discrete hydrated colored globules dispersed in an aqueous dispersing medium containing a film forming material. To impart the enhanced properties of long term stability and resistance to application by means of brush and roller, the globules are obtained by reacting two or more pigment containing hydrophilic colloids selected from carboxylated cellulose colloids, polysaccaride gums and acrylic polymers with at least two metal cations selected from Fe.sup.3+, Al.sup.3+, Ca.sup.2+, and Mg.sup.2+. The thus obtained colored globules contain from 2.5 to 20.0% by weight of pigment and fillers and 10 to 40% by weight of a film forming resin. The globules constitute and are about 60 to 90% by weight of the final composition, while the dispersing medium is 40 to 10% by weight of the final composition. The resistance of the globules to application by brush or roller is further enhanced if the film forming material in the dispersing medium has an average particle size within 4 to 200 microns.
