A recording sheet for ink jet printing is described, which consists of a support having coated onto said support at least two ink-receiving layers, wherein the ink-receiving layer situated next to the support contains nanoporous silicon dioxide with a positively charged surface and at least one binder and the ink-receiving layer situated further away from the support contains nanocrystalline, nanoporous aluminium oxide or aluminium oxide/hydroxide and at least one binder and, optionally, nanoporous silicon dioxide with a positively charged surface.

Recording sheet for ink jet printing

A recording sheet for ink jet printing is provided, which consists of a support having coated thereon at least one ink-receiving layer consisting of binders and at least one nanoporous inorganic compound, wherein the recording sheet contains a polynuclear aluminum hydroxo complex with 30 aluminum atoms. In a preferred embodiment, the surface of the nanoporous inorganic compound is modified by a treatment with the aluminum hydroxo complex with 30 aluminum atoms.

A system for forming a microporous ink receptive coating includes a fusible latex configured to coat a substrate, wherein the fusible latex includes a hard core material and a soft shell material, wherein the latex exhibits self-adhesive properties at a system operation temperature.

System and a method for forming a heat fusible microporous ink receptive coating

A recording sheet for ink jet printing is described, which consists of a support having coated thereon at least one ink-receiving layer consisting of binders, a nanocrystalline, nanoporous aluminum oxide or aluminum oxide/hydroxide, wherein the nanocrystalline, nanoporous aluminum oxide or aluminum oxide/hydroxide has been prepared in the absence of acids and has been treated with aluminum chlorohydrate. In a preferred embodiment of the invention the solution of aluminum chlorohydrate is aged at elevated temperature.

Print media and systems for preparing a fused ink-jet image are disclosed. One exemplary print medium, among others, includes a substrate, a porous ink-receiving layer disposed on the substrate, and a porous surface layer disposed on the porous ink-receiving layer. The porous surface layer includes polymer particles and a non-ionic stabilizing surfactant.

Print media

A Zero-order diffractive filter comprising a first layer () with a periodic diffractive microstructure, forming a waveguide, and at least one adjacent second layer (), wherein said first layer () has a refractive index that is higher than the refractive index of said second layer () by at least 0.2. At least one of said second layers () is a porous layer comprising nanopores. The period &#x39b; of the diffractive microstructure is between 100 nm and 3000 nm.
