Abstract: In a method of detecting a leak in a water impermeable membrane applied on a roof substrate, an electrical potential is created between a conductive detector on top of the membrane and the roof substrate causing current to flow between the roof substrate and the conductive detector through moisture in any leak in the membrane. The membrane is attached to the roof support substrate by an intervening layer therebetween which can be a primer or an adhesive layer which is caused to be electrically conductive by the addition an electrically conductive material. This allows the conductor on the roof substrate to which the potential difference is applied to be attached onto the roof substrate and covered by the layer underneath the membrane.

Abstract: An article having a nonwoven material and a coating contacting the nonwoven material, the coating comprising at least one fluorochemical and at least one antimicrobial agent. The fluorochemical comprises at least one fluoropolymer. The add-on value of the at least one antimicrobial agent on the nonwoven material is less than 0.75% and the coating provides at least a 4-log reduction within 5 minutes when measured using AATCC Method 100. The at least one antimicrobial agent is selected from the group consisting of a benzalkonium salt, a benzethonium salt, a octenidine salt, a chlorhexidine salt, free base chlorhexidine, triclosan and combinations thereof. The coating provides at least a 2-log reduction within 5 minutes when measured using AATCC Method 100.

Abstract: Thermal printers and methods for operating a thermal printer that applies donor material from donor patches on a donor ribbon to a received medium, the donor material being organized into sets, each set including at least one colored donor material patch and a protective material donor patch. A non-visible light is applied to a location on the donor ribbon, and a portion of the non-visible light that is not absorbed by the donor ribbon is sensed. The sensed non-visible light determines whether the portion of the donor ribbon to which the non-visible light has been applied has unused protective donor material thereon.

Abstract: A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes a binder including an hydroxyalkanoic acid polyester and one or more co-binder, wherein the co-binder is not polyester.

Abstract: A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes hydroxyalkyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.

Abstract: A dye-donor element, a method of printing using the dye-donor element, and a print assembly including the dye-donor element are described, wherein the dye-donor layer of the dye-donor element includes ethyl cellulose as a binder. The dye-donor element is capable of printing a defect-free image on a receiver element at a line speed of 2.0 msec/line or less while maintaining a print density of at least 2.0.

Abstract: A print assembly including a dye-donor element and a receiver element, wherein the print assembly has a donor having a dye-donor layer having a first glass transition temperature and at least one dye, and a receiver having a dye-receiving layer having a second glass transition temperature on a support, wherein the print assembly has a receiver/donor dye partition coefficient of at least 2.5 when the print assembly is heated above the higher of the first or second glass transition temperature for a time sufficient to achieve an equilibrium state of dye distribution between the dye-donor layer and dye-receiving layer. The print assembly can be used at fast print speeds of 2.0 msec/line or less.
