Abstract: A photolithographic resist with sensitivity for actinic radiation in the short wavelength, ultraviolet region is produced from (1) an organic film-forming material, and (2) an oxime carboxylate ester which releases a carboxylic acid on exposure to deep ultraviolet radiation, thereby rendering the composition more soluble in a developer in the exposed regions than in the unexposed regions. A process for the formation of an image is also disclosed comprising (1) exposing the above composition to actinic radiation in a pre-determined pattern and (2) treating the composition with aqueous base developer to remove the exposed areas. The image-forming process may be used in the production of printing plates and microelectronic circuits.

Abstract: A process for the preparation of isomerically pure sulfonic acids of 2-aminonaphthalenes having a fiber reactive substituent of the formula --(SO.sub.2 X) wherein X is --CH.sub.2 --CH.sub.2 --Z and Z is a substituent such as thiosulfato, phosphato or sulfato. The process comprises a first step of acylating the amino group of the substituted 2-aminonaphthalene to form a N-acyl derivative of the formula, R--CO--NH--A--SO.sub.2 X wherein A represents a naphthalene nucleus.
