The present invention is an array of sanitary tissue products. The array of sanitary tissue products comprises a first packaged article and a second packaged article. The first packaged article comprises a first rolled sanitary tissue product wound onto a first fibrous core. The second packaged article comprises a second rolled sanitary tissue product wound onto a second fibrous core. The second rolled sanitary tissue product is wound loosely relative to the first rolled sanitary tissue product. The second fibrous core has an axial strength greater than the first fibrous core.

Paper is disclosed for use in making repositionable or removable adhesive labels. The adhesive can be applied in patches or discrete areas to the paper or to a layer of material that cleans rollers in the manufacturing line and/or in printers. The adhesive can be applied in single or multiple layers. The paper is light weight paper and preferably thermal paper for use in POS printers.

A zirconia sintered body comprises zirconia and multiple different areas, including at least one upper area and at least one lower area having a different chemical composition and a different strength. The sintered body has a translucency and a strength with an inverse relationship. The translucency increases in one direction across the multiple different areas and the strength decreasing in the same direction across the multiple different areas. At least part of the sintered body has a total light transmittance of at least 35% and less than 53% to light with a wavelength at least at a point between 400 nm and 600 nm, and at least 51% and less than 57% to light with a wavelength at least at a point between 600 nm and 800 nm, at a thickness of 0.6 mm. At least a part of the sintered body has a strength of at least 925 Mpa.

A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including increasing amounts of yttria through a thickness of the green body. The green body is substantially opaque with a substantially consistent optical characteristic of non-translucency with respect to visible light across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of increasing translucency through a thickness of the dental prosthesis.

A dental zirconia system to produce translucent zirconia sintered bodies comprises at least two separate zirconia green bodies. At least one zirconia green body comprises zirconium oxide and a lower content of at least one other oxide summing to between 6.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. At least another zirconia green body comprises zirconium oxide and a higher content of at least one other oxide summing to between 7.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. The at least two zirconia green bodies each have at least some particles with a diameter of 100 nanometers to 1000 nanometers. The at least two zirconia green bodies have different amounts of the at least one other oxide with respect to one another.

A thermally expandable sheet includes a base, a thermally expansive layer, and a color adjustment layer. The thermally expansive layer is provided on a first side of the base and includes a thermally expandable material that distends in accordance with an amount of heat absorbed, the heat being generated from a thermal conversion layer that includes a thermal conversion material that converts electromagnetic waves to heat. The color adjustment layer is provided on at least one of the thermally expansive layer and a second side of the base and includes a color adjusting agent. When the thermal conversion layer is provided on the color adjustment layer, the color adjustment layer reduces a visual difference in color between a first region where the thermal conversion layer is provided and a second region where the thermal conversion layer is not provided.

An ink film construction comprising: (a) a printing substrate; and (b) at least one ink film, fixedly adhered to a top surface of the printing substrate, the ink film having an upper film surface distal to the top surface of the substrate, wherein a surface concentration of nitrogen at the upper film surface exceeds a bulk concentration of nitrogen within the film, the bulk concentration measured at a depth of at least 30 nanometers below the upper film surface, and wherein a ratio of the surface concentration to the bulk concentration is at least 1.1 to 1.

A dental zirconia system to produce translucent zirconia sintered bodies comprises at least two separate zirconia green bodies. At least one zirconia green body comprises zirconium oxide and a lower content of at least one other oxide summing to between 6.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. At least another zirconia green body comprises zirconium oxide and a higher content of at least one other oxide summing to between 7.5 wt % to 20 wt % based on a total weight percent of the zirconia green body. The at least two zirconia green bodies each have at least some particles with a diameter of 100 nanometers to 1000 nanometers. The at least two zirconia green bodies have different amounts of the at least one other oxide with respect to one another.

A method of making a translucent colored zirconia dental restoration comprises obtaining a zirconia green body, forming a dental restoration precursor from the zirconia green body, applying a color liquid to the precursor, and sintering the restoration precursor with regular sintering in air without post HIP processing. The zirconia green body comprises between 7 wt % to 20 wt % of stabilizer based on a total weight percent of the zirconia green body, and at least some particles with a diameter of 100 nanometers to 1000 nanometers. The zirconia green body is subsequently finally sinterable with regular sintering in air without post HIP processing to produce a translucent zirconia sintered body having a total light transmittance of at least 36% and less than 50% to light with a wavelength of 400 nm, and less than 55% to light with a wavelength of 600 nm, at a thickness of 0.6 mm.
