ABSTRACT:
A marking composition is provided which comprises a mixture of colored pigment, preferably red, and white pigment in amounts sufficient to provide an effective reflectance in the visible and infrared regions of from about 600 to about 1000 nm, e.g., a reflectance of at least 31.6 percent. The composition can therefore be suitable for the imprinting of indicia in a negative mode for reading by a code indicia scanning apparatus, e.g., such as those used in processing a Universal Product Code symbol. The present invention is particularly applicable to the marking of red product code symbols on a substrate which provides a background of low reflectance.
