Abstract
A coating composition comprising water and polyurethane particles including cationic triphenyl-phosphonium salt functional groups. Also disclosed is a coated printable medium, with an image-side and a back-side, comprising a base substrate and the coating composition, such as described herein, that is applied over, at least, one side of the base substrate, forming an image-receiving layer. Also disclosed is the method for making such printable medium.
Claims18
A coating composition for fabric printable media, comprising an aqueous dispersion of polyurethane particles including a backbone polymer with urethane linkages and cationic triphenyl-phosphonium salt functional groups attached to the backbone polymer.
A coated printable fabric, with an image-side and a back-side, the coated printable fabric comprising:
- a. a fabric substrate;
- and
- b. a coating composition applied over at least one side of the fabric substrate to form an image-receiving layer, the coating composition comprising an aqueous dispersion of polyurethane particles including a backbone polymer with urethane linkages and cationic triphenyl-phosphonium salt functional groups attached to the backbone polymer.
A method of making a coated printable fabric, the method comprising:
- a. applying a coating composition as a layer to a fabric substrate, the coating composition including an aqueous dispersion of polyurethane particles including a backbone polymer with urethane linkages and cationic triphenyl-phosphonium salt functional groups attached to the backbone polymer;
- and
- b. drying the coating composition to remove water from the fabric substrate to leave an ink-receiving layer thereon.
