## Abstract

A printable medium with a non-woven base composite supporting substrate; at least two coating layers, on the image side of the composite supporting substrate, that include an ink fixing layer, directly applied upon the supporting substrate, comprising a salt; and an image receiving layer, applied over the ink fixing layer, including pigment fillers and polymeric binders; and a barrier layer, containing a flame-retardant agent, applied on the backside of the composite supporting substrate. Also disclosed are the method for producing printed images using said media and the resulting printed material.
