<p>A non-photographic method for making patterns in organic polymer films comprising the sequential steps: (a) applying to a substrate an unpatterned first layer comprising a solid organic polymer which is dispersible in a predetermined eluant; (b) applying to the unpatterned first layer a patterned second layer comprising an agent which is capable of changing the dispersibility of the solid organic polymer in the predetermined eluant; (c) effecting patterned diffusion of the dispersibility-changing agent into the underlying solid organic polymer layer; and (d) removing the areas of the underlying solid organic polymer which are dispersible in the eluant by washing them with the predetermined eluant.</p> |
