Abstract: A method for converting a kinetically stable multiester of a naphthoquinone and an o-quinone diazide sulfonyl halide to a thermodynamically stable compound. The method comprises the steps of dissolving a phenol having at least two free phenolic hydroxyl groups and an o-naphthoquinone diazide sulfonyl halide in an aprotic solvent in the presence of a strong base, there being at least one mole of said naphthoquinone diazide sulfonyl halide per mole of phenol, reacting said phenol with said o-napthoquinone diazide sulfonyl halide until essentially of said o-naphthoquinone diazide sulfonyl halide is reacted with said polyhydroxy phenol, and following completion of said reaction, permitting the reaction product to remain in said solvent for a period of time of at least 15 minutes before recovering said photoactive compound. The photoactive compound formed by the process is suitable for the formation of photoresists and is less apt to precipitate from solution during storage.

Abstract: The invention relates to a conductive dispersions used for diverse purposes such a base for electroplating nonconductors. The dispersion are characterized by use of a stabilizing quantity of a stabilizer having repeating alylkene oxide groups and a hydrophilic-lipophilic balance in excess of 12.

Abstract: The invention is directed to purification of phenolic resins and to a process for preparing an organic photoresist coating composition. The process comprises reacting one or more phenols to form a crude phenolic resin. The crude phenolic resin formed is then separated from its reaction mixture and dissolved in an aqueous insoluble organic solvent in an organic solvent that is a solvent for the photoresist coating composition. The solution so formed is then mixed with an aqueous phase to extract water soluble impurities from the resin solution into the aqueous phase. Finally, the purified resin solution is further diluted with additional photoresist solvent.
