Abstract: A protective floor film includes a base film layer and a U.V. cured wear layer disposed on the base film layer. The wear layer has a thickness in a range of 2 to 25 micrometers. Methods of making protective floor film and methods of protecting a floor are also disclosed.

Abstract: A method of making an optochemical sensor, the method comprising: providing a reflective substrate having a major surface; affixing a detection layer comprising at least one intrinsically microporous polymer to at least a portion of the major surface; depositing a substantially continuous semi-reflective metallic layer on at least a portion of the detection layer, the semi-reflective metallic layer comprising palladium and having a network of fine irregular cracks therein; and heating the detection layer and semi-reflective metallic layer in the presence of molecular oxygen at a temperature sufficient to cause the cracks to widen. Sensors prepared according to method are also disclosed.

Abstract: A repellent article is disclosed comprising a layer of a thermoplastic polymer, and an adhesive layer having a fluorochemical repellent additive dispersed therein. The additive migrates from the adhesive layer to the thermoplastic polymer layer, rendering it oil- and/or water repellent.

Abstract: An antimicrobial article is disclosed comprising a layer of a thermoplastic polymer, and an adhesive layer having a antimicrobial agent dispersed therein. The antimicrobial article is useful, for example, surgical tapes, surgical drapes and wound dressings, and as disposable surfaces for food preparation and handling.

Abstract: A hydrophilic article is disclosed comprising a layer of a thermoplastic polymer, and an adhesive layer having a surfactant dispersed therein. The hydrophilic article is useful, for example, as ink-receptive substrates for aqueous inks, for fluid transport articles, wipes and absorbent articles.

Abstract: A stabilized fibrous article has fabric in contact with an adhesive layer containing one or more ultraviolet light stabilizers.

Abstract: Novel catalyst systems in cationically curable compositions provide colorless cationically cured compositions with improved degree of cure and thermal stability. The curable composition comprises at least one cationically curable monomer and a curing agent comprising Photocurative A or Photocurative B. Photocurative A comprises an effective amount of an accelerating photochemically active salt comprising a photochemically active cation and an accelerating anion, and an effective amount of an inhibiting non-photochemically active salt comprising a non-photochemically active cation and an inhibiting anion. Photocurative B comprises an effective amount of an inhibiting photochemically active salt comprising a photochemically active cation and an inhibiting anion, and an effective amount of an accelerating non-photochemically active salt comprising a non-photochemically active cation and an accelerating anion.
