Abstract
This invention relates to methods for making ink-jet recording media using hot-melt extrudable ink-receptive compositions. The melt-extrudable compositions comprise a blend of a melt-extrudable polyvinyl alcohol composition and poly(2-ethyl-2-oxazoline), a hydrolyzed copolymer of ethylene and vinyl acetate, ethylene/acrylic acid copolymers or ethylene/methacrylic acid copolymers. The invention also encompasses media made by such methods. The media can be used to form high quality, multicolored images.
Claims25
A method for producing an ink-jet recording medium, comprising the steps of:
- a) forming a hot-melt extrudable ink-receptive composition comprising a blend of about 50% to about 95% by weight of a melt-extrudable polyvinyl alcohol composition and about 5% to about 50% by weight of a compound selected from the group consisting of poly(2-ethyl-2-oxazoline), a hydrolyzed copolymer of ethylene and vinyl acetate, ethylene/acrylic acid copolymers and ethylene/methacrylic acid copolymers;
- and
- b) melt-extruding the ink-receptive composition onto a substrate to form an ink-jet recording medium having a coated ink-receptive layer.
A method for producing an ink-jet recording medium, comprising the steps of:
- a) forming a first hot-melt extrudable ink-receptive composition comprising a blend of about 50% to about 95% by weight of a melt-extrudable polyvinyl alcohol composition and about 5% to about 50% by weight of a compound selected from the group consisting of poly(2-ethyl-2-oxazoline), a hydrolyzed copolymer of ethylene and vinyl acetate, ethylene/acrylic acid copolymers and ethylene/methacrylic acid copolymers,
- b) forming a second hot-melt extrudable ink-receptive composition comprising a blend of about 50% to about 95% by weight of a melt-extrudable polyvinyl alcohol composition and about 5% to about 50% by weight of a compound selected from the group consisting of poly(2-ethyl-2-oxazoline), a hydrolyzed copolymer of ethylene and vinyl acetate, ethylene/acrylic acid copolymers and ethylene/methacrylic acid copolymers, and
- c) co-extruding the first and second ink-receptive compositions onto a substrate to form an ink-jet recording medium having multiple coated ink-receptive layers.
A method for producing an ink-jet recording medium, comprising the steps of:
- a) forming a hot-melt extrudable ink-receptive composition comprising a blend of about 50% to about 95% by weight of a melt-extrudable polyvinyl alcohol composition and about 5% to about 50% by weight of a compound selected from the group consisting of poly(2-ethyl-2-oxazoline), a hydrolyzed copolymer of ethylene and vinyl acetate, ethylene/acrylic acid copolymers and ethylene/methacrylic acid copolymers;
- b) forming a hot-melt extrudable tie composition comprising a polymer selected from the group consisting of polyurethane, ethylene-acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-acrylic acid-methacrylate terpolymer, poly(2-ethyl-2-oxazoline), and copolymers and mixtures thereof;
- c) forming a hot-melt extrudable moisture barrier composition comprising a polymer selected from the group consisting of polyolefins, ethylene-acrylic acid copolymer, ethylene-acrylate copolymer, and polyester, and copolymers and mixtures thereof;
- and
- d) co-extruding the ink-receptive, tie, and moisture barrier compositions onto a substrate to form an ink-jet recording medium having multiple ink-receptive layers.
A composite medium comprising at least a first sheet A and a second sheet B, wherein sheet A comprises a substrate Al selected from the group consisting of transparent and translucent substrates and at least one layer A2 thereon, and sheet B comprises a substrate B1 and layer A2 comprises a thermoplastic composition that can be imaged by an ink jet printer using one or more inks comprising at least 20 weight percent water.
