Abstract: A decorative dye colorant for use on various types of natural stone, such as granite, marble, limestone, and soapstone. The colorant is formed by mixing a solvent soluble dye with a suitable solvent, such as a ketone or an alcohol to form a dye solution. The solvent enables the dye to penetrate easily into the pores or openings located in the surface of the stone to color the stone so as not to mar the appearance of the surface of the stone. The dye is resistant to removal or discoloration, but may be removed by extended contact of certain chemicals with the dye. To permanently prevent the removal of the dye, a sealer is applied over the dye to prevent any such materials from contacting the dye. The sealer is comprised of an aliphatic urethane mixed with the alcohol xylol that also includes ultraviolet light resistant properties to prevent the dye from fading over time.

Abstract: The present invention is directed to polishing pads useful in determining an end to the useful wear life thereof. In a simple embodiment of the present invention, a polishing pad that is used with slurries is dyed on one side in a manner that causes the dye to permeate the pad to a limited depth that does not cause total coloring.

After dyeing the pad, the pad is attached to the polishing platen. During the polishing operation, a color change signals a time to stop the polishing operation and change the pad. With multiple colors in the pad, limited only by the ability to dye the pad with uniform depth levels, characteristic wear patterns can be observed and adjustments made accordingly to prolong and optimize pad life.
