Abstract
By carrying out a plasma discharge treatment for a support in which an image receiving layer comprising a void structure is formed, the void structure of the surface layer is subjected to hydrophilic treatment to enhance the water absorption capability of a recording media in the thickness direction (in the depth direction) and to enhance image receiving capability. Further, by making a portion more adjacent to the surface hydrophobic, an image disorder after receiving ink droplets is minimized. Still further, by continually carrying out an image receiving layer forming plasma treatment, it is possible to more efficiently produce an ink jet recording medium.
Claims21
A surface treatment method of a substrate having a layer with voids provided on a support, said method comprising, in sequential order:
- first, treating said substrate to a first plasma treatment such that said layer with voids becomes hydrophilic;
- and
- second, treating said substrate to a second plasma treatment such that the surface of the layer with voids becomes hydrophobic.
A production method of an ink jet paper having a layer with voids on a support comprising
- first, treating said paper to a first plasma treatment such that said layer with voids becomes hydrophilic, and
- second, treating said paper to a second plasma treatment such that the surface of said layer with voids becomes hydrophobic.
