    摘要： A water resistant slide fastener, comprising:
    a pair of stringer tapes (14,16) each having first and second opposed surfaces (18,20) said stringer tapes (14,16) being positioned substantially parallel and side-by-side so as to provide said stringer tapes (14,16) with inner and outer edges;
    a series of gripper elements (22) positioned along said inner edges for releasably securing said stringer tapes (14,16) together; and
    a water resistant layer (26) on at least one surface of said first and second surfaces (18,20) and overlying said inner edges and said series of gripper elements (22), wherein
    said water resistant layer (26) comprises a polyurethane film having a multilayer structure including an inner layer (60) arranged facing said stringer tapes (14,16) and having a first Shore A hardness, and an outer layer (62) having a second Shore A hardness, wherein said second Shore A hardness is greater than said first Shore A hardness.
