Abstract: An inkjet recording element comprising an ink-permeable microvoided substrate comprising a porous ink-receiving layer over and adjacent to an ink-permeable microvoided substrate layer comprising, in a polyester continuous phase, a polyester ionomer, wherein the microvoided substrate layer and the porous ink-receiving layer both having interconnecting voids. Also disclosed is an inkjet printing process, comprising the step of providing an ink-jet printer with such an inkjet recording element.

Abstract: A phosphor screen comprises an inorganic phosphor capable of absorbing X-rays and emitting electromagnetic radiation having a wavelength greater than 300 nm. The phosphor is disposed on a support that has a reflective substrate comprising a continuous poly(lactic acid) first phase and a second phase dispersed within the continuous poly(lactic acid) first phase. The second phase contains microvoids that in turn contain barium sulfate particles. This support provides improved reflectivity particularly at shorter wavelengths.

Abstract: A reflective optical film comprises a layer containing a polyester voided with inorganic particles such as barium sulfate in a size and an amount sufficient to provide a visible light reflectivity of at least 93%, a void volume of 40 to 70%, the film at least (1) having a thickness of less than 150 ?m, or (2) containing UV particles in amounts sufficient to provide a UV light reflectivity of less than 40%.

Abstract: An inkjet recording element comprises a permeable microvoided polylactic-acid-containing layer having interconnecting voids. The invention is also directed to method of using such recording elements in an inkjet printing process and to sheets useful for making such inkjet recording elements and other media.

Abstract: A single or multilayer sheet comprising a microvoided layer permeable to low surface tension liquids has a continuous phase comprising a polylactic-acid-based material and interconnecting microvoids, said microvoided layer having a total absorbent capacity of at least about 14 cc/m2. The invention is also directed to an a method of making a sheet material comprising such a permeable microvoided layer, which method comprises extruding a sheet comprising a layer of a polylactic-acid-based material containing inorganic particles by extrusion, and stretching the sheet biaxially to form interconnected microvoids around the inorganic particles.

Abstract: A reflective optical film comprising a layer containing a polylactic acid voided with inorganic particles in a size and an amount sufficient to provide a visible light reflectivity of at least 96%. Optionally the film contains UV particles in amounts sufficient to provide a UV light reflectivity of less than 40%.
