Ribbons for impact printing and thermal transfer printing are made in many cases with ink formulations based on polyamides, such as EMEREZ* or VERSAMIDE**. It could be desirable to extend the use of such ribbons to color printing without altering the basic formulations except for the pigment, for example, by incorporating reactive dyes. Color ribbons for impact printing and thermal transfer printing can be made for use in color printing without altering the basic formulations except for the pigment by the availability of a family of commercial dyes, called reactive dyes. These dyes are extensively used in the fabric-dying industry for dying cotton, wool and nylon.
