Abstract

A fabric print medium containing a fabric base substrate and a coating composition applied to the fabric base substrate. The coating composition includes a non-halogenated flame retardant agent having phosphorous-containing ingredient and nitrogen-containing ingredient at a 1:1 ratio, a water-soluble polymer binder and a water-soluble high-valence metal complex. Also disclosed are the method for making such fabric print medium and the method for producing printed images using said material.
