Aspects of the present disclosure relate to a printable medium including a polyurethane dispersion. As an example, a printable medium may include a fabric base substrate, with an image-side and a back-side. A film-forming layer may be applied to the image-side of the fabric base substrate, including an anionic polyurethane dispersion having a reactive group on a backbone of the polyurethane dispersion and a reactive group on a capping unit of the polyurethane dispersion. An ink-receiving coating layer may be applied over the film-forming layer, including a crosslink agent.

The present invention relates to surface modifying agents for polymeric and/or textile materials, methods of making and/or using a surface modifying agent to modify and functionalize polymeric and/or textile materials, and/or methods of using surface modified or functionalized polymeric and textile materials, and/or products using or incorporating surface modified or functionalized polymeric and textile materials. For example, the surface modifying agent in precursor form can be styrene sulfonyl azide monomer, polymer or copolymer capable of undergoing a chemical reaction in the presence of heat or light to form one or more styrene sulfonated nitrene monomers, polymers or copolymers, which are capable of chemically reacting with the surface of a polymeric or textile material to endow a specific or desired chemical surface functionality to the surface of a polymeric or textile material. Furthermore, the present invention is possibly preferably directed to a surface modifying agent which comprises a styrene sulfonated nitrene monomer, polymer or polymer containing one or more nitrene functional groups, which are capable of chemically reacting via an insertion reaction into one or more carbon-hydrogen bonds on the surface of a polymeric or textile material in order to chemically attach a specific or desired chemical functionality to the surface of a polymeric or textile material.

A fabric coating composition can include water, from 3 wt % to 95 wt % oxazoline reactive compound by dry weight including an oxazoline group, and from 3 wt % to 70 wt % cationic charging agent by dry weight. The fabric coating composition can have a pH from pH 2 to pH 6.
