Recording sheet for ink jet printing

摘要

A recording sheet comprises at least two ink-receiving layers coated onto a support, each consisting of binders and at least one nanocrystalline, nanoporous compound. The ink-receiving layer situated next to the support contains nanoporous silicon dioxide with a positively charged surface and the ink-receiving layer situated further away from the support contains nanocrystalline, nanoporous aluminum oxide/hydroxide. A recording sheet comprises at least two ink-receiving layers coated onto a support, each consisting of binders and at least one nanocrystalline, nanoporous compound. The ink-receiving layer situated next to the support contains nanoporous silicon dioxide with a positively charged surface and the ink-receiving layer situated further away from the support contains nanocrystalline, nanoporous aluminum oxide/hydroxide. The ink-receiving layer situated further away from the support contains, in addition, silicon dioxide with a positively charged surface. The recording sheet contains an intermediate layer consisting of nanocrystalline, nanoporous aluminum oxide/hydroxide, nanoporous silicon dioxide with a positively charged or a mixture of these compounds, between the two ink-receiving layers. The intermediate layer contains, in addition, a binder.
