Claim Text:
1. An imprint process for transferring a shape of a desired transfer shape area that a mold has onto a work-material while said work-material is interleaved between said mold and a transfer substrate blank, comprising: an adhesion-layer formation step of forming an adhesion layer on said transfer substrate blank to form a transfer substrate, a filling step of filling said work-material in said transfer shape area while said mold is brought in proximity to said transfer substrate with said work-material interleaved between said mold and said adhesion layer, a curing step of curing said work-material, and a releasing step of releasing said mold off from said work-material, wherein in said adhesion-layer formation step, an adhesive containing a plurality of monomolecular structures each comprising a single tetravalent atom having one hydrolysable group and two inert groups and a reactive functional group bonded to said tetravalent atom is brought into contact with said substrate blank, followed by an adhesive removal step of removing a portion of the adhesive remaining unreacted with the substrate blank, thereby forming an adhesion layer having no bumps of more than 5 nm in height.
