Abstract: The present invention relates generally to a microporous film, in particular to a microporous film which can be used in an ink-jet recording medium of photographic quality that has excellent ink absorption speed, good drying characteristics and a good image printing quality. According to the present invention, an ink-jet recording medium is provided, comprising a support to which a (micro)porous or water swellable layer is adhered. The present invention is further directed to methods for obtaining such a medium.

Abstract: The invention is directed to an ink jet recording medium comprising at least: a support, and a microporous film adhered to said support, wherein said microporous film is characterised by: an oriented thermoplastic film comprising at least a filler, said film having interconnecting channels between the pores, with a void volume between 30 to 80 volume percent of the total microporous film, and having a volume of pores with a pore diameter between 50 nm and 1000 nm of less than 60 volume % of the total void volume of said microporous film, as determined by the mercury intrusion porosimetry method.

Abstract: The invention is directed to a process for the preparation of polymer laminated base paper, said process comprising laminating a base paper web on at least one side thereof with at least one polymer layer by extrusion-coating at a coating speed of 300 m/min or more, wherein the said base paper web is heated prior to laminating.
