Abstract: A process for preparing an ink receptive substrate comprising the steps of: (i) contemporaneously applying a first and a second curable composition to a support such that the first composition is closer to the support than the second composition; (ii) allowing the first and second compositions to diffuse into each other to provide an inhomogeneous, curable coating on the support; and (iii) curing the inhomogeneous coating to form a polymer layer having a lower porosity nearer the support than further away from the support.

Abstract: A process for preparing an advertisement comprising printing an ink onto an ink receptive substrate, wherein the ink receptive substrate comprises a transparent or translucent support layer and a porous layer comprising polymerised monomers at least 30wt % of which monomers are alkylene glycol diacrylate(s) having an Mw below 500.

Abstract: The present invention relates to a porous membrane obtainable by providing a mixture of at least one type of curable monomer and a solvent, applying said mixture to a support, curing said mixture, thereby causing phase separation between the crosslinked monomer and the solvent, subjecting the resulting porous membrane to a washing and/or drying step to remove said solvent and re-curing the porous membrane after drying or partial drying the membrane. The invention further relates to image recording materials, in which these porous membranes are used.

Abstract: The present invention relates to a porous membrane formed by curing at least one type of anionic monomer by UV irradiation in the presence of a photo-initiator wherein said porous membrane has at least 0.1 meq negative charges per m2, preferably between 0.3 and 5 meq negative charges per m2. The invention further relates to image recording materials, in which these porous membranes are used.

Abstract: The present invention relates to a process for making microporous membranes by curing compounds through radiation. The invention further relates to image recording materials, in which these microporous membranes are used. According to the present invention a microporous membrane is prepared by the steps of providing a curable compound solvent mixture, wherein the concentration of said curable compound is between 20 and 80 weight percent and wherein at least 30 weight percent of said solvent is water; applying said mixture to a support; curing said curable compound mixture by exposing to radiation, thereby causing phase separation between the crosslinked curable compound and the solvent; subjecting the resulting microporous membrane to a drying or washing step to remove said solvent; and optionally separating the support and the microporous membrane.

Abstract: The present invention relates to a recording medium, in particular an ink-jet recording medium of photographic quality that has excellent lightfastness. According to the present invention an ink-jet recording medium is provided, comprising a support and an ink-receiving layer adhered to said support, wherein the ink-receiving layer is a multilayer comprising a top layer, which top layer comprises a modified gelatin, and at least one intermediate layer in between said support and said top layer, wherein said intermediate layer comprises a mixture of a PVA-based polymer and a water soluble polymer. The present invention is further directed to methods for obtaining and using such a medium.

Abstract: The present invention relates to a recording medium, in particular an ink-jet recording medium of photographic quality that has excellent color stability while keeping good 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 at least an underlayer and an overlayer is supplied, wherein one layer comprising an optical brightener is further away from said support than another layer which comprises a UV absorbing agent. The present invention is further directed to methods for obtaining and using such a medium.
