ABSTRACT:
Disclosed are tellurium (IV) compounds represented by the formula: ##STR1## wherein: D is a Lewis base function containing a group VA or VIA donor atom;
Q represents the atoms necessary to complete a 5- or 6-membered ring, when taken together with C, D and Te, when m is 1 and represents the atoms linking C and D when m is greater than 1;
R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, alkyl and aryl;
X is an anion;
n is 1 or 2; and
m is an integer from 1 to 500.
These compounds are useful in an image-forming combination comprising the described Te(IV) compound and a reducing agent. The image-forming combination is useful in a variety of materials, including a dry amplification element.
