Abstract A WELL DISPERSED WATER VEHICLE COATING SUSPENSION AND METHOD OF PREPARING SAME FOR APPLYING A HIGHLY ADHERENT LUMINESCENT COATING ONTO A SUBSTRATE. THE SUSPENSION COMPRISES FINELY DIVIDED ADHERENCE PROMOTING PARTICLES AND FINELY DIVIDED LUMINESCENT MATERIAL UNIFORMLY DISPERSED IN A WATER LACQUER SYSTEM. AN AQUEOUS SOLUTION IS PREPARED IN WHICH DETERMINED AMOUNTS OF ALUMINUM OXIDE ADHERENCE PROMOTING PARTICLES ARE UNIFORMLY DISPERSED. A WATER SOLUBLE POLYACRYLIC ACID BINDER IS THEN MIXED INTO THIS AQUEOUS SOLUTION. THE AMOUNT OF WATER SOLUBLE BINDER ADDED IS CONTROLLED WITH RESPECT TO THE AMOUNT OF ADHERENCE PROMOTING PARTICLES TO INSURE THAT THE PARTICLES REMAIN DISPERSED AND DO NOT FLOCCULATE.
