Title:
IMAGING ELEMENT CONTAINING A BLOCKED PHOTOGRAPHICALLY USEFUL COMPOUND
Document Type and Number:
WIPO Patent Application WO2001096946
Kind Code:
A3
Abstract:
Blocked photographically useful groups decompose thermally via a Lossen rearrangement reaction, including, for example, compounds represented by the following structure: F. In the above structure, the substituents are as defined in the application. Such compounds have good reactivity and can by used to block photographically useful compounds such as developing agents until thermally activated under preselected conditions. Compounds according to the present invention are especially useful in color photothermographic imaging elements.
