, (2008/06/13)
This invention relates to a color-shifted dye compounds containing at least one thermally unstable carbamate moiety which are useful in thermal imaging. These compounds may be represented by the formula [M--(X)q ]p D wherein M is a carbamate moiety; X is --N=, --SO2 -- or --CH2 --; D taken with X and M represents the radical of a color-shifted organic dye, said carbamate moiety M comprising a tert-alkoxycarbonyl group, STR1 wherein R' is halomethyl or alkyl.
