ESTERS OF OXIMSULPHONIC ACIDS AND THEIR USE AS LATENT SULPHONIC ACIDS. THE INVENTION REFERS TO THE USE OF OXIMSULFONIC ACID ESTERS ACCORDING TO FORMULA I IN WHICH M IS 0 O 1, X IS 1 O 2; R1 REPRESENTS FOR EXAMPLE FENYL SUBSTITUTED, R2 HAS FOR EXAMPLE, ONE OF THE DEFINITIONS OF R1 OR DENOTA FENYL INSUBSTITUTED, ALCANOYLL WITH 1 TO 6 CARBON ATOMS, INSTITUTED BENZOYLON, 2-AXYLOXYBUTYL, AND OR R1 AND R2, FOR EXAMPLE, IN THEIR CASE TOGETHER FORM A RING WITH GROUP CO, R3 WHEN X IS EQUAL TO 1 REPRESENTS FOR EXAMPLE I RENT WITH 1 TO 18 ATOMS OF CARBON, PHENYLL OR FENANTRILE, IN WHICH THE PHENYL AND PHENYL RADICALS THEY MAY BE OF THE INSUBSTITUTED OR SUBSTITUTED TYPE OR R3 WHEN X IS EQUAL TO 2, DENOTED FOR EXAMPLE ALKYLENE WITH 2 TO 12, PHENYLENE OR WELL OXIDIPHENYLENE, AS THE SUBSTITUTED, OXIDIFENYLENE, OR SUBSTITUTE TYPES ARE OF A SUBSTITUTE OR SUBSTITUTE TYPE. LATENT ACIDS, ESPECIALLY IN THE CASE OF WAVE LENGTHS OF MORE THAN 390 NM, INCLUDING THE USE OF SUCH COMPOUNDS FOR THE ELABORATION OF PHOTO-RESISTANT MATERIALS. |
