N2 - The lithographic potential of the photo-Fries reaction rests on the ability to selectively dissolve either the exposed or the unexposed areas of a polymer film. Typically, it is expected that in the case of polymers containing phenolic ester groups, the photoproducts, being substituted phenols, should dissolve in aqueous base while the unchanged starting polymer should remain undissolved. Similar results should also be within reach using the photo-Fries reaction on polymers containing aromatic amide groups. Although it is anticipated that, in some cases, the photostabilizing effect of the rearrangement products might have a deleterious effect on the imaging characteristics of the polymers, it is nevertheless likely that imaging of thin films should remain possible. The polymers used in this study included poly(p-acetoxystyrene), poly(p-formyloxystyrene), poly(p-acetamidostyrene), poly(phenyl methacrylate), and poly(methacryl anilide).
