A method for producing a primary laminate including a tabstock by feeding a seal laminate comprising bottom food contact layers including a foil layer and a top polyester layer to a laminating station wherein either the foil layer of the underside of the polyester layer has been printed; simultaneously feeding a tabstock, which is narrower than the seal laminate, to the laminating station such that the bottom of the tabstock and the top polyester layer of the seal laminate come into contact to form a primary substrate, simultaneously feeding a plastic film stock; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock.

A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The cyclic olefin polymer (A) may comprise a cyclic olefin copolymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.

This invention relates to a multilayer coating system derived from Titanium dioxide free aqueous coating compositions. The multilayer coating system comprises at least two layers including a layer of base coating which provides good hiding function for substrates and a second layer of clear top coating which provides surface protection functions for the coating system. The base coating composition comprises an opaque (co)polymer having at least one void per (co)polymer particle. The top coating composition comprises a duller (co)polymer chosen from a multi-stage (co)polymer, a single stage crosslinked (co)polymer, and mixtures thereof.

A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.

Broadband reflectors include a UV-reflective multilayer optical film and a VIS/IR-reflective layer. In various embodiments, the VIS/IR reflective layer may be a reflective metal layer or a multilayer optical film. Concentrated solar power systems and methods of harnessing solar energy using the broadband reflectors and optionally comprising a celestial tracking mechanism are also disclosed.

Packaging and a method of making the packaging is disclosed. The packaging includes a substrate with an asymmetrical coextrusion attached there to. The coextrusion includes an ethylene vinyl alcohol layer that is disposed toward the substrate.

The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied. The coating agents are useful for providing a coating that can be further functionalized (for example, by application of additional coating layers), or for providing desirable properties to a surface.

An anisotropic conductive film includes a first connection layer and a second connection layer formed on one side of the first connection layer. The first connection layer is obtained by photo-radical polymerization of a photo-radical polymerizable resin layer containing an acrylate compound and a photo-radical polymerization initiator. The second connection layer includes a thermal- or photo-, cationic or anionic polymerizable resin layer containing an epoxy compound and a thermal- or photo-, cationic or anionic polymerization initiator, or a thermal- or photo-radical polymerizable resin layer containing an acrylate compound and a thermal- or photo-radical polymerization initiator. Conductive particles for anisotropic conductive connection are arranged in a single layer on a second connection layer-side surface of the first connection layer.

The subject of the present invention is a semi-rigid or flexible and low-gloss impact-reinforced acrylic material. The acrylic material according to the invention comprises a nanostructured matrix constituted of at least one thermoplastic acrylic block copolymer and at least one highly crosslinked acrylic copolymer. The matrix comprises at least one thermoplastic acrylic block copolymer. The highly crosslinked acrylic copolymer comprises, as sole monomer or as predominate monomer, MMA, that is to say that it comprises, by weight, more than 50%, advantageously more than 65% of MMA. The acrylic material according to the invention comprises from 60% to 99% by weight of matrix for 40% to 1% by weight of crosslinked copolymer. These materials may be converted by injection molding, extrusion, co-extrusion, extrusion-blow molding for producing parts, profiles, sheets or films for example.
