ABSTRACT:
The aqueous base polish composition, which is particularly adaptable for use as a household floor polish, contains a non-volatile, solid film former, such as an acrylic copolymer, dispersed in the aqueous phase or base, a water-soluble, acid-base indicator, such as thymolphthalein, which is colored at a pH above a predetermined level and is colorless at a lower pH, in a sufficient amount to impart a distinctive original color to the composition and a sufficient amount of an alkaline material, such as potassium hydroxide, to raise the overall pH of the composition above that predetermined level, e.g., above about 11 or higher. Upon being applied on the surface of flooring, the colored polish composition retains its original color for a finite period of time while in the liquid state, e.g., 30 seconds to 2 minutes, and becomes colorless as the water evaporates during formation of a protective film finish. The color indicator becomes an integral part of the dried clear and colorless film. Upon the application of an aqueous cleaning or stripping solution used for removing one or more coats of the dried film after use and having a pH above a determined level, the film reverts to the original color of the composition so that one can readily observe whether the old film has been completely removed before the floor becomes dry.
The film former can include optional ingredients, such as a wax, an alkali-soluble resin and a permanent plasticizer to improve the wear resistance and finish properties of the resultant film. The polish composition can also include fugitive plasticizers or coalescing aids to facilitate the formation of a smooth, continuous protective film and a chelating agent to increase the color retention time after application.
