Abstract: Novel multifunctional unsaturated polyester polyols, UV-curable top coat formulations including these polyols, and a one-step process for preparing these polyols, are disclosed. Surface coverings and surface covering components including these top coat formulations are also disclosed. The polyols are generally formed by the ring opening polymerization of a lactone with a compound of the formula (R1)aR(OH)b, where a+b>2. R1 is a double bond-containing moiety such as allyl, vinyl, vinylidene, vinyl ether, acrylate, and the like. R is generally an alkyl, aryl, aralkyl, alkaryl, ether or ester group, including substituted versions thereof. R can be a polymer, including polymers with a plurality of functional groups. Examples of lactone groups which can be used include caprolactone, lactide and glycolide.

Abstract: An instrument for evaluating fluorescence of a heterogeneous tissue includes means for exciting a two-dimensional portion of the tissue surface with excitation radiation at a plurality of excitation wavelengths, means for collecting emission radiation from the two-dimensional portion of the tissue surface simultaneously with excitation of the portion, and means for forming a two-dimensional excitation-emission map of the excitation radiation and the simultaneously collected emission radiation and spatially averaging the excitation and emission radiation.

Abstract: Waterborne coating compositions, methods of applying such compositions, and substrates coated with such compositions are described. The compositions include an aqueous dispersion of a polyurethane resin, an epoxy resin, and a polyvinyl chloride resin. The compositions can also include an aminoplast such as a melamine, and one or more curing agents. Additionally, the compositions can include flatting agents, colored metallic and/or polymeric particles, hard particles, surfactants, rheology modifiers, defoamers, and coalescing aids. The coating composition can be applied to virtually any surface and cured using conventional heat curing techniques, whether or not there is a chemically embossed layer. However, it is advantageously used in surface coverings in combination with a chemically embossed layer. In one embodiment, the surface covering includes a chemically embossed layer and a cured top layer, which are both cured in a single heating step or plurality of heating steps.
