Abstract: An electronic signature capture system and process meets the legal requirements of a valid electronic signature while also providing electronically signed documents that have the appearance, and thus equivalent acceptability, of a traditional pen-and-ink signature. The documents can be signed using a mouse, a stylus, a touch screen, a graphics tablet, or other suitable input device to draw a signature analogue on the screen similar to signing a paper document with a pen. A fingerprint image, retinal scan image, or other similar biometric input may be captured in addition to or instead of a signature. The signature analogue is saved and linked to a particular user and to particular documents. The signature analogue may be combined with the document in a composite image file, or the signature analogue may be applied dynamically to appropriate document components to assemble an executed document as needed.

Abstract: The invention is a pressure sensitive adhesive (PSA) composition, which is the ultraviolet radiation (UV) cured reaction product of a polyester-polyether-based urethane acrylate, one or more acrylate monomers, and a UV photosensitizer. The polyester-polyether-based urethane acrylate is the reaction product of between about 50 and 90 wt-% of a polyester diol having a molecular weight ranging from about 500 to 3200; between about 10 and 50 wt-% of a polyether polyol having a molecular weight ranging from about 1000 to 6000; between about 1 and 5 wt-% of a hydroxy-functional acrylate; and a polyisocyanate.

Abstract: The present invention relates to flexible package laminates useful in food packaging that are prepared using a liquid, UV curable, oligomeric, adhesive composition that does not require a photoinitiator.

Abstract: The subject invention relates to a foundry binder system which cures in the presence of a volatile amine curing catalyst comprising (a) an epoxy resin, (b) an acrylated organic polyisocyanate, (c) a reactive unsaturated acrylic monomer, acrylic polymer, or mixtures thereof, and (d) an oxidizing agent comprising a hydroperoxide. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes which are used to make metal castings.

Abstract: A crystalline grindable end-blocked prepolymer useful in providing a polyurethane elastomer having a 100% modulus less than approximately 250 psi, tensile of 3500 to 6500 psi, and less than 30% initial tensile set, said prepolymer being the product of reacting an organic polyisocyanate, a long chain crystalline diol having an average molecular weight of approximately 500 to 5000, a polyhydroxy cross-linking agent, and an end-blocking agent.

Abstract: Novel polyurethanes especially suited for applications requiring initial heat resistance in a non-alcohol, non-exotic solvent system such as methyl ethyl ketone and having peel strengths of at least 5 pounds per linear inch (pli) uncrosslinked at about 180.degree. to about 200.degree. F., optionally containing crosslinkers, and which are typically used in the automobile industry, are described.

Abstract: Improved adhesive compositions for laminating plastic and particularly vinyl films to metal are described which contain about 15 to 30 percent by weight of a phenolic resol having a methylol content of about 15 to 50 percent by weight, about 25 to about 40 percent by weight of certain nonfunctional polyurethanes having a molecular weight of at least 20,000 and preferably 60,000 to 300,000 and about 35 to 55 percent by weight of a vinyl solution polymer, all in an organic solvent. The nonfunctional polyurethanes are thermoplastic polyesterurethanes devoid of reactive isocyanate and hydroxyl groups and are derived from monomeric polyisocyanates and polyhydroxy compounds chain-extended with a low molecular weight diol, preferably a cycloaliphatic diol, to the desired molecular weight. When the polyhydroxy compound is a polycaprolactone polyol, it is essential that chain extension be effected with a cycloaliphatic diol, preferably dimethylolcyclohexane.
