Abstract
Inkjet receptor media are disclosed that have both a fluid management system and a pigment management system for use with pigmented inkjet inks that produce vibrant, durable images. The fluid management system is provided by microporous media with the presence of surfactants, if needed. The pigment management system is provided by either fluorinated silica particles or multivalent metal salts impregnated into pores of the microporous media. Methods of making and using are also disclosed.
Claims35
An inkjet receptor medium comprising:
- a porous substrate having a fluid management system and a pigment management system in contact with surfaces of pores of the substrate, wherein the pigment management system comprises functionalized particulates within the pores of the porous substrate and the fluid management system comprises a surfactant.
A method of making an inkjet receptor medium comprising:
- (a) preparing a pigment management system;
- (b) imbibing the pigment management system into pores of a porous substrate, wherein the pigment management system once imbibed into the pores comprises functionalized particulates within the pores of the porous substrate;
- and
- (c) imbibing a fluid management system into the pores of the porous substrate wherein the fluid management system comprises a surfactant.
An inkjet receptor median comprising:
- a porous membrane of a synthetic polymer having a fluid management system and a pigment management system in contact with surfaces of pores of the membrane, wherein the pigment management system comprises a multivalent metal salt coating along the surfaces of the pores of the porous membrane, wherein the fluid management system comprises a surfactant, and further wherein the size of the pores of the porous membrane is at least 0.2 μm, and is no greater than about 2.0 μm, and wherein the pore size is a bubble point pore size measured according to ASTM F-316.
An inkjet receptor medium comprising:
- a porous substrate having a fluid management system and a pigment management system in contact with surfaces of pores of the substrate wherein the pigment management system comprises fluorinated silica agglomerates that are capable of agglomerating pigment particles in a pigment-containing ink used to print the inkjet receptor medium.
A method of making an inkjet receptor medium comprising:
- (a) preparing a pigment management system;
- (b) imbibing the pigmemt management system into pores of a porous membrane of a synthetic polymer, wherein the pigment management system once imbibed into pores of the porous membrane comprises a multivalent metal salt coating along the surfaces of the pores of the porous membrane;
- and
- (c) imbibing a fluid management system into the pores of the porous membrane wherein the fluid management system comprises a surfactant, and further wherein the size of the pores of the porous membrane is at least 0.2 μm, and is no greater than about 2.0μm, and wherein the pore size is a bubble point pore size measured according to ASTM F-316.
An inkjet receptor medium comprising a porous substrate comprising a multivalent metal salt coating and an anionic surfactant in contact with surfaces of pores of the porous substrate, and further comprising a pigmented ink image therein, wherein the size of the pores of the porous substrate is at least 0.2 μm, and is no greater than about 2.0 μm, and wherein the pore size is a bubble point pore size measured according to ASTM F-316.
An inkjet receptor medium comprising a porous substrate comprising fluorinated silica agglomerates in contact with surfaces of pores of the porous substrate.
A method of making an inkjet receptor medium comprising:
- (a) preparing a pigment management system;
- (b) imbibing the pigment management system into pores of a thermally induced phase separated microporous membrane of a synthetic polymer, wherein the pigment management system once imbibed into pores of the microporous membrane comprises a multivalent metal salt coating along the surfaces of the pores of the microporous membrane;
- and
- (a) imbibing a fluid management system into the pores of the microporous membrane wherein the fluid management system comprises a surfactant, and further wherein the size of the pores of the microporous membrane is at least 0.2 μm, and is no greater than about 2.0 μm, and wherein the pore size is a bubble point pore size measured according to ASTM F-316.
