Inkjet-receptive article
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 solvent. A preferred vinyl lactam copolymer is polyvinylcaprolactam (PVCap)—vinyl acetate (VA). Also disclosed are solvent-based compositions for forming an inkjet-receptive coating on a substrate comprising: (i) a vinyl lactam polymer or copolymer; (ii) a solvent; (iii) optionally, a pigment; and (iv) polymer resin diluent.
1. The 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 solvent wherein said vinyl lactam copolymer is polyvinylcaprolactam (PVCap)-vinyl acetate (VA) having a molecular weight of about 6,000g/mol to about 40,000 g/mol.
2. The inkjet-receptive article according to claim 1 wherein said substrate is vinyl plastic, polyester plastic, polyolefin plastic, paper, canvas, glass, ceramic, wood or a metal.
3. The inkjet-receptive article according to claim 1 comprises a pigment selected from the group consisting of silica, barium sulfate, calcium carbonate, titanium dioxide, alumina, silver alone or in combinations thereof.
4. The inkjet-receptive article according to claim 3 wherein said pigment is present in the range of about 5 wt. % to about 90 wt. % of the solid coating.
5. The inkjet-receptive article according to claim 1 comprising a diluent in an amount of about 5 wt. % to about 80 wt. % of the coating.
6. The inkjet-receptive article according to claim 5 wherein said diluent is a powdered polymer resin selected from the group consisting of vinyl chloride-vinyl acetate copolymer, a carboxyl-modified vinyl copolymer, an epoxy-modified vinyl copolymer, a hydroxyl-modified vinyl copolymer, acrylate based copolymers or mixture thereof.
7. The inkjet-receptive article according to claim 1 further comprising a surfactant in amount of up to 4 wt. % of the coating.
8. The inkjet-receptive article according to claim 7 wherein said surfactant is selected from the group consisting of anionic, cationic, non-ionic, amphoteric, alkali metal soaps, ammonium salts of long chain fatty acids, quaternary fatty ammonium halides, quaternary fatty ammonium acetates, quaternary fatty ammonium suphates, or polyethylene oxide chains attached to hydrocarbons.
9. The inkjet-receptive article according to claim 1 , optionally comprising plasticizers, wax, driers, chelating agents, antioxidants, deodorants, biocides, fluorescent agents, reflecting agents, and/or fragrances.
