Prepolymer material, polymer material, imprinting process and their use

An imprinting process for the manufacture of a polymer article comprising a surface with a relief on a surface using at least one mold or stamp comprising an imprinting surface with a relief, being structured inversely to the relief of the polymer article, comprising:

• a) applying at least one surfactant, comprising a fluorinated organo silane, onto the surface of the mold or stamp, wherein the imprinting surface is at least partly coated with a thin film of the surfactant;
• b) bringing the mold or stamp into contact with a prepolymer material wherein the relief of the imprinting surface of the mold or stamp is at least partly filled with the prepolymer material;
• c) polymerizing the prepolymer material while in contact with the mold or stamp, yielding the polymer article with the relief on its surface;
• and
• d) releasing the polymer article from the mold or stamp.
