Claim 6:
7. A method of forming a patterned layer, the method comprising:
providing a layer of an imprinting composition, the imprinting composition being capable of solidification under the influence of a basic organic group;
contacting the imprinting composition layer with a stamp comprising a patterned surface such that the layer is solidified by crosslinking and a relief feature pattern is imprinted into the layer of the cured imprinting composition;
wherein the stamp comprises an elastomer stamp body including an organic polymeric bulk portion containing an amount of a basic organic substance, the substance comprising an amount of the basic organic group suitable to influence solidification of the imprinting composition upon contacting of the stamp with the imprinting composition;
retaining the contact between the layer of the imprinting composition and the stamp until the imprinted composition has reached a desired degree of solidification; and releasing the stamp from the solidified layer of the imprinting composition to yield the patterned layer.
