    摘要： Positive lithographic patterns are produced by imagewise exposing to actinic light, x-ray or e-beam a polymer having pendant recurring groups selected from the group consisting of--COO--CH.sub.2 --CH(OH)--(CH.sub.2).sub.x --H wherein x is 0-20;--COO--CH.sub.2 --CH(OH)--(CH.sub.2).sub.y --HE--(CH.sub.2).sub.z --H; and mixtures thereof; wherein HE is O or S; and each y and z individually is 1-18; and mixtures thereof; and then developing the polymer in an aqueous base developer. The developer can be any of the conventional or commonly used ones as well as the special developers discussed below.Positive lithographic patterns are also produced by imagewise exposing to actinic light, x-ray or e-beam a photosensitive polymeric material to provide free carboxylic acid groups; and then developing by contacting with an aqueous developer solution of about 0.001% to about 1% by weight of a compound containing at least one amino group and at least two sulfonate groups selected from the group consisting of alkali metal sulfonate group, ammonium sulfate group, and mixtures thereof; or developing by contacting with an amine in vapor form and contacting with an aqueous solvent.
