This invention relates to a transfer mold comprising a transfer pattern layer having a positive protrusion pattern surface comprised of a polymeric material, supported by a base layer comprised of a different material than the transfer pattern layer. The transfer pattern layer is formed from a composition curable at ambient temperature. The invention also relates to methods of producing positive and negative replications of the transfer mold as well as methods of providing a fine structure (e.g. plasma barrier ribs) from a molded replica of transfer mold.
L'invention concerne un moule de transfert comprenant une couche de motifs de transfert munie d'une surface de motifs saillants positifs formée dans un matériau polymère, soutenue par une couche de base formée dans un matériau différent de celui de la couche de motifs de transfert. La couche de motifs de transfert est formée dans une composition durcissable à température ambiante. L'invention porte également sur des procédés permettant de produire des répliques positives et négatives du moule de transfert, et sur des procédés permettant d'obtenir une structure fine (p.ex. des arêtes de barrière plasma) à partir d'une réplique moulée du moule de transfert.
