PHOTOSENSITIVE COMPOSITION

摘要

Aromatic diazonium salt is prepd. for use as a highly photosensitive composition. Thus, 2,6-dimethyl aniline (50g) is suspended in water, and methylation of the amino group is performed with sodium hydroxide. The obtained N,N-dimethyl compd. is dissolved into hydrochloric acid and zinc chloride is added. Recrystallization with diluted hydrochloric acid gives 2,6-dimethyl-N,N-dimethylaniline hydrochloric zincchloric complex salt I.
