  • Patent number: 10365070
    Abstract: A ballistic resistant article includes at least one consolidated composite, wherein the at least one consolidated composite includes a layer A and a layer B bonded to one another. Each, layer A and B exhibits a first surface, a second surface opposite to the first surface, and a cross-section extending from the first surface to the second surface, and includes a network of fibers having a strength of at least 800 mN/tex (1100 MPa), and the fibers in each layer A and B are impregnated with a matrix material. The matrix material is distributed along the cross-section of each layer in a concentration gradient in which the concentration starts with a maximum value on the first surface, decreases along the cross-section and reaches a minimum value on the second surface. The matrix material includes a mixture of a polychloroprene, and a random copolymer of vinyl chloride and an acrylic ester.
    Type: Grant

  • Patent number: 6210854
    Abstract: An aqueous developable photosensitive element comprising a support and a photosensitive layer provided thereon, said layer containing (a) an elastomeric microgel binder having an elastomeric core which can be crosslinked and a thermoplastic noncrosslinked shell, (b) an initiator, (c) an ethylenically unsaturated monomer or oligomer and optionally (d) a basic compound capable of neutralizing the acidic functionality and method of use to make an aqueous developable flexographic printing plate is described.
