Abstract
The present invention provides less expensive ink jet recording papers having high glossiness and high durability and being capable of quickly absorbing inks without causing bleeding. Accordingly, the present invention provides an ink jet recording paper having an ink-receiving layer provided on a porous resin film, wherein the porous resin film has a liquid absorption capacity measured in accordance with “Japan TAPPI No.51-87” of 0.5 ml/m2 or above and the ink-receiving layer has a surface glossiness (JIS-Z8741: measuring method at 60°) of 40% or above. It is preferable that the ink jet recording paper contains at least one member selected from among alumina, alumina hydrate and amorphous silica in the ink-receiving layer.
Claims35
An article comprising an ink-receiving layer provided on a porous resin film, wherein the porous resin film has a liquid absorption capacity measured in accordance with “Japan TAPPI No.51-87” of 0.5 ml/m2 or above and the ink-receiving layer has a surface glossiness, measured according to the JIS-Z8741 method at 60°, of 40% or above.
A method for making an article, comprising
- forming a porous resin film by mixing 30 to 90% by weight of a thermoplastic resin and from 10 to 70% by weight of a fine inorganic powder or an organic powder;
- extruding the porous resin film to form a sheet;
- providing pores in the sheet;
- coating the sheet with an ink-receiving layer comprising from 70 to 95% by weight of an inorganic filler having an average particle diameter of 350 nm or below and from 5 to 30% of a binder resin.
