Abstract

A developing solution comprising (A) at least one aromatic hydrocarbon having a boiling point of from 150.degree. to 300.degree. C.; (B) at least one alcohol represented by the following formula (I): R.sup.1 OH (I) wherein R.sup.1 represents an aliphatic or alicyclic alkyl group having from 5 to 12 carbon atoms, --C.sub.n H.sub.2n Ar, --(C.sub.m H.sub.2m O).sub.p C.sub.q H.sub.2q+1, a furfuryl group or a hydrogenated furfuryl group, an alkyl group substituted by an acyl group or an epoxy group, or --CH.sub.2 CH.sub.2 (OCH.sub.2 CH.sub.2).sub.r OR.sup.2 ; in which Ar represents an aromatic group; n represents an integer of from 1 to 3; m represents an integer of from 2 to 6; p represents 1 or 2; q represents 0 or an integer of from 1 to 4; R.sup.2 represents a hydrogen atom or an alkyl group; and r represents 0, 1 or 2; and (C) at least one compound represented by the following formula (II): ##STR1## wherein R.sup.3 and R.sup.4 are the same or different and each represents an alkyl group having from 3 to 6 carbon atoms; the proportions of components (A), (B), and (C) being from 25 to 70% by weight, from 20 to 50% by weight, and from 0.001 to 40% by weight, respectively, each based on the sum of components (A), (B), and (C).
