HYDROLYTICALLY STABLE TELLURIUM (IV) COMPOUNDS AND COMPOSITIONS

摘要

Disclosed are tellurium(.V) compounds represented by the formula: 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; R1 and R2 are independently selected from the group consisting of hydrogen, alkyl and aryl; x is an anion; n is 1; 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 simplification element.
