ABSTRACT:
Polyfunctional compounds containing .alpha.-diazo-.beta.-keto ester units and sulfonate units are disclosed. The polyfunctional compounds have high sensitivity in the deep UV and high thermal stability. Processes for producing the compounds are disclosed. A preferred process first synthesizes .beta.-ketoester/sulfonate precursors and then uses diazo transfer to convert the precursors into the novel compounds. Radiation-sensitive mixtures containing the compounds are also disclosed.
