Abstract

An inkjet-receptive article includes a substrate having a coating thereon which is a vinyl lactam polymer or copolymer.

Claims

1. An inkjet-receptive article comprising a substrate having a coating thereon comprising a vinyl lactam polymer or copolymer and a polymer resin diluent coated from a non-aqueous solvent.

2. An inkjet-receptive article according to claim 1 wherein said vinyl lactam polymer is a polyvinylpyrrolidone polymer or copolymer.

3. An inkjet-receptive article according to claim 1 wherein said vinyl lactam copolymer is polyvinylpyrrolidone-vinyl acetate.

4. An inkjet-receptive article according to claim 1 wherein said substrate is a plastic.

5. An inkjet-receptive article according to claim 4 wherein said substrate is a vinyl, polyester, polyolefin, or paper.

6. An inkjet-receptive article according to claim 1 which includes a pigment.

7. An inkjet-receptive article according to claim 1 wherein said pigment is silica or barium sulfate, or mixtures thereof.

8. An inkjet-receptive article according to claim 7 wherein said pigment is present in an amount of up to 30 wt. % of the coating.

9. An inkjet-receptive article according to claim 8 wherein said pigment is present in an amount of 5-15 wt. % of the coating.

10. An inkjet-receptive article according to claim 1 which includes a diluent.

11. An inkjet-receptive article according to claim 10 wherein said diluent is present in an amount of up to 40 wt. % of the coating.

12. An article according to claim 11 wherein said diluent is a powdered polymer resin.

13. An article according to claim 12 wherein said diluent is present in an amount of 5-15 wt. %.

14. An article according to claim 1 which includes a surfactant.

15. An article according to claim 14 wherein said surfactant is present in amount of up to 4 wt. % of the coating.

22. A solvent-based composition according to claim 14 wherein (a) is a powder or is in a non-aqueous solution.

16. A solvent-based composition for forming an inkjet-receptive coating on a substrate comprising:

(a) a vinyl lactam polymer or copolymer,

(b) a non-aqueous solvent,

(c) optionally a pigment, and
