ABSTRACT:
4'-Azidobenzal-2-methoxyacetophenone is an excellent photosensitive compound and can give a photosensitive composition together with an alkaline-aqueous-solution-soluble polymer which can be insolubilized in an alkaline aqueous solution by photochemical curing with 4'-azidobenzal-2-methoxyacetophenone, and if necessary together with an organic solvent, said composition showing a very small change in viscosity with the lapse of long time.
