Claims
- 1. A dye-reactive fixative comprising a water-soluble or water-dispersible polymer or oligomer selected from the group consisting of polyethylene glycol terminally capped with one or more epoxycyclohexyl groups; a mixture of polyethylene glycol and poly(butadiene); and polyethylene glycol derivatized with cyanuric chloride.
- 2. A dye-reactive fixative according to claim 1 wherein the polymer or oligomer comprises polyethylene glycol terminally capped with one or more epoxycyclohexyl groups.
- 3. A dye-reactive fixative according to claim 1 wherein the polymer or oligomer comprises a mixture of polyethylene glycol and poly(butadiene).
- 4. A dye-reactive fixative according to claim 3 wherein the poly(butadiene) is a copolymer of polybutadiene and maleic anhydride.
- 5. A dye-reactive fixative according to claim 1 wherein the polymer or oligomer comprises polyethylene glycol derivatized with cyanuric chloride.
- 6. A colorfast dyed web comprising a dye-reactive fixative compound covalently bonded with the dye on the web to affix the dye to the web, wherein the dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer selected from the group consisting of polyethylene glycol terminally capped with one or more epoxycyclohexyl groups; a mixture of polyethylene glycol and poly(butadiene); and polyethylene glycol derivatized with cyanuric chloride.
- 7. A colorfast dyed web according to claim 6 wherein the polymer or oligomer comprises polyethylene glycol terminally capped with one or more epoxycyclohexyl groups.
- 8. A colorfast dyed web according to claim 6 wherein the polymer or oligomer comprises a mixture of polyethylene glycol and poly(butadiene).
- 9. A colorfast dyed web according to claim 8 wherein the poly(butadiene) is a copolymer of polybutadiene and maleic anhydride.
- 10. A colorfast dyed web according to claim 1 wherein the polymer or oligomer comprises polyethylene glycol derivatized with cyanuric chloride.
