Abstract
An improved process for the manufacture of vesiculated beads has been developed which can be used for the production of semi-gloss or satin finished paints. The process involves mixing an oil-phase containing a cross-linkable polyester resin in solution with a monomer co-polymerizable with the resin and an aqueous phase containing an emulsifying agent under conditions such that globules of the oil-phase are formed having a diameter of less than 1.5 microns. The emulsion containing the globules also contains a base and the amount of the emulsifying agent is from 3 to 16 grams per 100 ml of the oil-phase and the volume fraction has a value of 0.2 to 0.4 and X as defined is from 4 to 8. Preferably the beads are pigmented with titanium dioxide pigment.
