Abstract
Provided are permanent tissue markings comprising at least one colored compound comprising a thermally activatable fragmentation group and at least one infrared absorbing compound, wherein the at least one colored compound is capable of being rendered colorless by unimolecular fragmentation of the thermally activatable fragmentation group when the tissue marking is non-imagewise exposed by a source of infrared radiation.

A tissue marking comprising at least one colored compound comprising a thermally activatable fragmentation group and at least one infrared absorbing compound, wherein the at least one colored compound is capable of being rendered colorless by unimolecular fragmentation of the thermally activatable fragmentation group when the tissue marking is non-imagewise exposed by a source of infrared radiation.
A tissue marking comprising:
- at least one colored compound comprising:
- a thermally activatable fragmentation group;
- and
- at least one infrared absorbing compound;
- wherein the at least one infrared absorbing compound comprises a cyanine, phthalocyanine, squarylium, azulenium, indophenol, naphthoquinone, or anthraquinone;
- and
- wherein the at least one colored compound is capable of being rendered colorless by unimolecular fragmentation of the thermally activatable fragmentation group when the tissue marking is non-imagewise exposed by a source of infrared radiation.
