Abstract

The present disclosure is drawn to fabric print media and a method of coating a fabric substrate to form a fabric print medium. The fabric print medium can comprise a fabric substrate, a primer layer applied to the fabric substrate, and an ink-receiving layer applied to the primer layer. The primer layer can include a film-forming polymer and a phosphorus- or nitrogen-containing compound. The ink-receiving layer can comprise a phosphorus- or nitrogen-containing compound, a cationic metal complex, and non-deformable particles.

First claim

What is claimed is:

1. A fabric print medium, comprising:
a fabric substrate;
a primer layer applied to the fabric substrate, the primer layer including a film-forming polymer and a first phosphorus- or nitrogen-containing compound, wherein the film forming polymer is a polyurethane or modified polyacrylate, and wherein the film forming polymer has a glass transition temperature from −60° C. to −20° C. and a surface energy from 35 dyne/cm to 50 dyne/cm; and
an ink-receiving layer applied to the primer layer, the ink-receiving layer comprising a second phosphorus- or nitrogen-containing compound, a cationic metal complex, and non-deformable particles.

2. The fabric print medium of claim 1 , wherein the fabric substrate is woven, knitted, non-woven, or tufted, and the fabric substrate comprises natural or synthetic fibers selected from the group of wool, cotton, silk, rayon, thermoplastic aliphatic polymers, polyesters, polyamides, polyimides, polypropelene, polyethylene, polystyrene, polytetrafluoroethylene, fiberglass, polytrimethylene, polycarbonates, polyester terephthalate, or polybutylene terephthalate.

3. The fabric print medium of claim 1 , wherein at least one of the first or second phosphorus- or nitrogen-containing compound is an organophosphate independently selected from the group of:

where R 1 , R 2 , and R 3 are independently C 1 -C 12 branched or straight chained alkyl, aryl, bisphosphate, or halogen.

4. The fabric print medium of claim 1 , wherein at least one of the phosphorus- or nitrogen-containing compound is selected from the group of tris(1,3-dichloroisopropyl)phosphate, tris(2-chloroisopropyl)phosphate, tris(2-chloroisopropyl)phosphate, dimethyl phosphonate, diethyl phosphonate, dimethyl propyl phosphonate, diethyl N,N-bis(2-hydroxyethyl)aminomethyl phosphonate, oligomeric chloroalkyl phosphates, chloroalkyl phosphates, aryl phosphates, melamines, and mixtures thereof.

5. The fabric print medium of claim 1 , wherein at least one of the phosphorus- or nitrogen-containing compound is a phosphorus- and nitrogen-containing compound selected from the group of ammonium polyphosphate, poly(4,4-diaminodiphenyl methane spirocyclic pentaerythritol bisphosphonate), 1,4-di(diethoxy thiophosphamide benzene), and mixtures thereof.

6. The fabric print medium of claim 1 , wherein cationic metal complex comprises i) a charged complex ion comprising coordinate covalent bonds or dative bonds, and wherein the charged complex ion has from 2 to 9 ligands attached thereto; ii) at least two charged complex ions, wherein a ligand donates an electron pairs to the at least two charged complex ions and then acts as bridge between the at least two charged complex ions; or iii) an aluminum-based multivalent salt.

7. The fabric print medium of claim 1 , wherein the non-deformable particles are prepared from hydrophobic addition monomers selected from the group of C 1 -C 12 alkyl acrylate and methacrylate monomers, aromatic monomers, hydroxyl containing monomers, carboxylic acid containing monomers, vinyl ester monomers, vinyl benzene monomers, C 1 -C 12 alkyl acrylamide and methacrylamide monomers, olefin monomers, and combinations thereof.

8. The fabric print medium of claim 1 , wherein the non-deformable particles are selected from the group of polytetrafluoroethylene (PTFE), silica, silicone, paraffin wax, carnauba wax, montan wax, and combinations thereof.

9. The fabric print medium of claim 1 , wherein the non-deformable particles are reactive polymeric particles that form a cross-linked film when heat is applied thereto.

10. The fabric print medium of claim 1 , wherein at least one of the primer layer and the ink-receiving layer comprises a sodium silicate.

11. A method of coating a fabric substrate to form a fabric media substrate, comprising:
impregnating a fabric substrate with a primer coating composition to form a primer layer, the primer coating composition including a liquid carrier, a film-forming primer, and a first phosphorus- or nitrogen-containing compound, wherein the film forming polymer is a polyurethane or modified polyacrylate, and wherein the film forming polymer has a glass transition temperature from −60° C. to −20° C. and a surface energy from 35 dyne/cm to 50 dyne/cm;
drying the primer layer;
applying an ink-receiving layer coating composition onto the primer layer to form an outermost ink-receiving layer, the ink-receiving layer coating composition including a liquid carrier, a second phosphorus- or nitrogen-containing compound, a cationic metal complex, and non-deformable particles; and
drying the ink-receiving layer.

12. The method of claim 11 , further comprising the step of calendaring the primer layer, the ink-receiving layer, or both layers.

13. The method of claim 11 , wherein drying of the primer layer is under heat at temperature greater than 200° F., and drying of the ink-receiving layer is under heat at a temperature less than 200° F.

14. The method of claim 11 , further comprising coating both a front side and a back side of the fabric substrate with the primer layer and ink-receiving layer.

15. The fabric print medium of claim 1 , wherein the cationic metal complex comprises an aluminum-based multivalent salt.

16. The method of claim 11 , wherein the cationic metal complex comprises an aluminum-based multivalent salt.

17. The fabric print medium of claim 1 , wherein the ink-receiving layer further comprises a surfactant having a more than 12 carbon backbone.

18. The fabric print medium of claim 17 , wherein the surfactant is a cationic surfactant.
