  • Methods of creating patterns on substrates and articles of manufacture resulting therefrom
    Patent number: 6860956
    Abstract: Methods of creating patterns on substrates are presented, and articles of manufacture resulting therefrom. One method comprises applying a first surface energy modifier to an applicator to form a coating on the applicator; contacting the coating with a receiving member, the receiving member having a topography, the coating only contacting and remaining on at least some protrusions; exposing the first modified receiving member to a second surface energy modifier, thereby forming a second modified receiving member having surface modified recesses; applying a composition comprising a polymeric material to the second modified receiving member, the composition substantially conforming to the topography of the surface modified protrusions and the surface modified recesses; and contacting the composition-coated, surface modified protrusions with a substrate for a time and under conditions sufficient to transfer the polymeric material on protrusions to the substrate.
