Patent ID: 8557351

Claim:
A method of adhering a layer to an imprint lithography substrate, said method comprising: (i) depositing a composition comprising a cross-linker and a multi-functional reactive compound upon said imprint lithography substrate, wherein the multi-functional reactive compound comprises: (a) an organic backbone group; and (b) a first functional group and a second functional group coupled to opposing ends of the organic backbone group, wherein the functional groups are different, and wherein the first functional group is acrylate and the second functional group is selected from the group consisting of a carboxylic group and an epoxy group; (ii) thermally curing said composition, wherein thermally curing comprises: (a) forming interactions between the imprint lithography substrate and the multi-functional reactive compound through the second functional group; (b) forming interactions between the substrate and the second functional group of the multi-functional reactive compound through the cross-linker; and (c) forming covalent or ionic bonds between the cross-linker and the multi-functional reactive compound through the second functional group; (iii) depositing a polymerizable material on said thermally cured composition to form said layer; and (iv) exposing the polymerizable material to actinic energy to polymerize the polymerizable material, wherein polymerizing the polymerizable material comprises forming covalent bonds between the polymerizable material and the multi-functional reactive compound in the thermally cured composition through the first functional group.
