Patent ID: 8262757

Claim:
An abrasive article comprising: a backing; abrasive grains; a polymer binder; and about 0.0000001 weight percent to about 0.01 weight percent based on the weight of the polymer binder of an infrared radiation absorbing dye, wherein the polymer binder, the infrared radiation absorbing dye, and the abrasive grains are disposed over the backing, and wherein the infrared radiation absorbing dye is selected from the group consisting of cyanine dyes, croconium dyes, metal phthalocyanine dyes, metalated azo dyes, metalated indoaniline dyes, amminium dyes, metal complex dyes, and combinations thereof having a peak absorption intensity in the infrared radiation spectrum within a wavelength of about 0.7 to 1.3 microns and an absorption intensity at all wavelengths in the non-infrared spectrum of less than about fifty percent (50%) of the peak absorption intensity within the infrared spectrum.
