Abstract
The invention provides an ink jet recording medium having at least two ink absorbing layers provided on or above a non-water-absorbing support, wherein: a first ink absorbing layer, which is provided uppermost among the at least two ink absorbing layers, contains at least silanol-modified polyvinyl alcohol, polyaluminum chloride and pseudo boehmite alumina, and a second ink absorbing layer, which is adjacent to the first ink absorbing layer, contains at least pseudo boehmite alumina having a secondary particle diameter of 80 nm or less, polyvinyl alcohol, boric acid, and a water-soluble zirconium salt. The invention further provides a method of manufacturing the ink jet recording medium.
Claims4
An ink jet recording medium comprising at least two ink absorbing layers provided on or above a non-water-absorbing support, wherein:
- a first ink absorbing layer, which is provided uppermost among the at least two ink absorbing layers, comprises silanol-modified polyvinyl alcohol, polyaluminum chloride and pseudo boehmite alumina, and
- a second ink absorbing layer, which is adjacent to the first ink absorbing layer, comprises pseudo boehmite alumina having a secondary particle diameter of 80 nm or less, polyvinyl alcohol, boric acid, and a water-soluble zirconium salt.
A method of manufacturing an ink jet recording medium comprising at least two ink absorbing layers provided on or above a non-water-absorbing support, the method comprising:
- applying, on or above the non-water-absorbing support, a first coating liquid comprising pseudo boehmite alumina having a secondary particle diameter of 80 mn or less, polyvinyl alcohol, boric acid, and a water-soluble zirconium salt;
- drying the applied first coating liquid to form a second ink absorbing layer, which is adjacent to a first ink absorbing layer to be provided uppermost among the at least two ink absorbing layers;
- applying, above the non-water-absorbing support, a second coating liquid comprising silanol-modified polyvinyl alcohol, polyaluminum chloride and pseudo boehmite alumina;
- and
- drying the applied second coating liquid to form the first ink absorbing layer.
