Abstract: The present invention relates to multilayer composites which show special visual effects while maintaining other beneficial properties such as melt strength and impact strength. In one embodiment the present invention relates to a multilayer composite comprising, in sequence, (i) optionally, an outer layer comprising an acrylic resin which is substantially transparent to visible light, (ii) a second layer comprising a first rubber modified thermoplastic resin which is substantially transparent to visible light, and at least one additive to provide a special visual effect; (iii) a third layer comprising a light-blocking layer; (iv) a fourth layer comprising a second rubber modified thermoplastic resin different from said first rubber modified thermoplastic resin; (v) optionally, a fifth layer comprising a tielayer; and (vi) optionally, a substrate layer. In other embodiments the present invention relates to articles made from the composite.

Abstract: The present invention relates to formed resinous articles derived from compositions comprising an ASA resin and a special visual effect additive.

Abstract: A method to attach hydrophilic and/or ionogenic coatings to metallic surfaces robustly. Important applications for the invention extend to sensor types, various biomedical devices, and additional technologies requiring metal coatings with specified properties, such as sensors that employ the Quartz Crystal Microbalance (QCM) principle. This is a method to produce an adherent hydrogel against a metal surface by gelling a liquid mixture of components. The implementation of the invention for QCM ion sensors employs poly(allylamine) (PAH) hydrogels. The reaction of PAH with N-Acetylhomocysteine thiolactone (AHTL) (Fluda) in water under basic conditions produces thiol groups. This reaction removes ion exchange functionality and permits robust attachment of the hydrogel to the QCM's gold electrode.
