NOVEL DIAZONAPHTHOQUINONESULFONIC ACID BISPHENOL DERIVATIVE USEFUL IN PHOTO LITHOGRAPHIC SUB MICRON PATTERNING AND A PROCESS FOR PREPARATION THEREOF

The present invention provides novel diazonaphthoquinonesulfonic acid bisphenol derivatives. More particularly, the present invention relates to photo restive coating comprising alkali-soluble resin, a photoactive compound and a surfactant. The photoresist film prepared has less then one micron. The photoactive compound is soluble or swellable in aqueous alkaline solutions and is diazonaphthoquinonesulfonic bisphenol esters of the general formula (A), wherein DNQ represents a 2-Diazo-1-naphthoquinone-4-sulfonyl, 2-Diazo-1-naphthoquinone-5-sulfonyl, 1-Diazo-2-naphthoquinone-4-sulfonyl groups and R1 R1 represents an alkyl, aryl and substituted aryl groups. The invention also provides a process for coating and imaging the light-sensitive composition.

Polymer electrolyte and process for producing the same

A polymer electrolyte having, in a main chain, a structural unit represented by the following formula (1):-[Ar1-(SO2-N-(X+)-SO2-Ar2)m-SO2-N-(X+)-SO2-Ar1-O]- wherein Ar1 and Ar2 independently represent a divalent aromatic groups, m represents an integer of 0 to 3, and X+ represents an ion selected from hydrogen ion, an alkali metal ion and ammonium ion, which is excellent in proton conductivity, thermal resistance and strength. The polymer electrolyte is soluble in solvents and has excellent film forming property and recycling efficiency.
