Abstract: The invention relates generally to the field of inkjet recording media and inkjet printing methods. More specifically, the invention relates to a porous base layer of an inkjet recording element, the base layer comprising precipitated calcium carbonate having scalenohedral morphology.

Abstract: An inkjet recording element comprising a porous ink-receiving layer having interconnecting voids is disclosed in which an upper surface of the ink-receiving layer has been subjected to plasma treatment, and wherein the upper surface of the ink-receiving layer, prior to the plasma treatment, has a measured carbon elemental content of at least 40 percent. The invention can provide increased dot spread.

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: An inkjet recording system comprising a pigment-based ink in combination with a recording element having a porous substrate with relatively large pores and a relatively thin overlying surface layer which traps pigment particles, from an applied pigmented ink, at or near the surface while not unduly restricting ink flow into the underlying porous substrate.

Abstract: An x-ray intensifying screen is disclosed containing magnesium tantalum niobium oxide as a phosphor in an ordered corundum crystalline form. In addition, small amounts of at least one alkali metal other than lithium can be present. Potassium, rubidium and cesium are each capable of increasing luminescence. The x-ray intensifying screens are useful in radiographic applications where it is important to reduce subject exposure to x-rays and also to create clear, sharp images.
