Claim 0:
1. A method of providing a patterned layer, the method comprising: providing a substrate comprising a surface to which a layer of a compound is applied, the compound comprising: at least one condensable group reactive with surface groups of said surface by condensation reaction and a basic group for accepting protons, wherein the basic group comprises a Bronsted base group;
applying a layer of a polycondensable imprinting composition onto the layer of the compound; and
imprinting the imprinting composition layer with a patterned stamp, wherein polycondensation of the imprinting composition occurs during the imprinting providing said patterned layer
wherein the at least one condensable group comprises an alkoxy silyl group, the compound being thereby grafted to the surface via oxygen-silicon bonds; and
the condensable group comprises two or three alkoxy groups bonded to the same silicon of the alkoxy silyl group.
