A process for using a substantially light-insensitive mono sheet direct thermal imaging material for producing a non-retro-reflective readable object attachable to a second object for information purposes, the imaging material including a support, a thermosensitive element and an attaching layer, wherein the thermosensitive element contains a substantially light-insensitive organic silver salt, a reducing agent therefore in thermal working relationship therewith, a binder and does not contain a di- or triarylmethane dye precursor compound possessing within its di- or triarylmethane structure an aryl group substituted in the ortho position to the meso carbon atom with an S-containing moiety ring-closed on the meso carbon atom selected from a thiolactone, dithiolactone and thioether moiety.
