This invention relates to a method for preparing at least one mold part of a two-part mold useful for transferring a hydrophobic top coat from a mold onto an optical substrate. Further, the invention relates to a method for easily transferring a hydrophobic top coat from a mold onto the anti-reflecting coating of a coated optical substrate. Additionally, the invention relates to a method which provides improved adhesion of the hydrophobic top coat onto an optical substrate and in particular onto an anti-reflecting coating of a coated optical substrate. The invention also discloses a mold part useful in such methods.
