    摘要： DIAZO-OXIDES OF SULFONIC ACID AMIDES AND/OR ESTERS CONTAINING A PLURALITY OF AROMATIC ETHER GROUPS, E.G. THE BIS-DIAZO-OXIDE OF NAPHTHALENE SULFONIC ACID AMIDE OF THE P-AMINOPHENYL DIETHER OF BISPHENOL A, AND THEIR USE IN PRINTING PLATES, ELECTRONICS, AND OTHER FIELDS WHICH ARE LIGHT-SENSITIVE MATERIALS. UPON EXPOSURE THROUGH A TRANSPARENCY THE DIAZO-OXIDES DECOMPOSE AND THE DECOMPOSITION PRODUCTS CAN BE REMOVED BY ALKALI. WHERE THE DIAZOOXIDE HAS NOT BEEN EXPOSED AND DECOMPOSED THE PLATE WILL ACCEPT PRINTING INK SO AS TO BE ABLE TO PRINT LARGE NUMBERS OF POSITIVE REPRODUCTIONS OF THE ORIGINAL TRANSPARENCY, OR IT MAY RESIST THE ACTION OF ETCHANTS.
