Abstract
An ink receptive article including a substrate having on at least a portion of a major surface thereof an antistatic layer, and wherein the antistatic layer has on at least a portion of a major surface thereof an ink receptive layer, wherein the ink receptive layer includes a crosslinked polymer selected from the group consisting of polyurethanes, polyethers, polyesters, polyacrlylics, polyureas, copolymers thereof, and blends thereof.
Claims53
An ink receptive article, comprising:
- a substrate having on at least a portion of a major surface thereof an antistatic layer, wherein the antistatic layer is selected from the group consisting of vanadium pentoxide, antimony oxide, lithium salts in combination with a PEG functionalized material, quaternary ammonium salts and a PEDT/PSS (poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate)) conductive polymer;
- and
- an ink receptive layer on at least a portion of the antistatic layer, wherein the ink receptive layer comprises:
- a major component of a crosslinked urethane polymer and copolymers and blends thereof with acrylic polymers, and about 5% to about 20% by weight of an ink absorber selected from the group consisting of metal oxides and silicas, and wherein the ink receptive layer further comprises a printed indicia comprising an organic solvent-based ink.
An ink receptive article comprising a substrate comprising an oriented foam layer, wherein the substrate has an antistatic layer on at least a portion of a major surface thereof, the antistatic layer comprising a static dissipating compound selected from the group consisting of vanadium pentoxide, antimony oxide, and a PEDT/PSS (poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate)) conductive polymer, and an ink receptive layer on a least a portion of the antistatic layer, wherein the ink receptive layer comprises a major component of at least one crosslinked urethane polymer and about 5% to about 20% by weight of an ink absorber selected from the group consisting of metal oxides and silicas, and wherein the ink receptive layer further comprises a printed indicia comprising an organic solvent-based ink.
An ink receptive article comprising a substrate having thereon an antistatic layer selected from the group consisting of vanadium pentoxide, antimony oxide, and a PEDT/PSS (poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate)) conductive polymer;
- and
- an ink receptive layer, wherein the ink receptive layer comprises:
- a major component of a urethane polymer copolymers and blends thereof with acrylic polymers,
- a crosslinker, wherein the crosslinker is present at 1 wt % to 10 wt % of the amount of polymer in the ink receptive layer, and
- about 5% to about 20% by weight of an ink absorber selected from the group consisting of metal oxides and silicas,
- and wherein the ink receptive layer further comprises printed indicia comprising an organic solvent-based ink.
A security document comprising a substrate having on at least a portion of a major surface thereof an antistatic layer selected from the group consisting of vanadium pentoxide, antimony oxide, and a PEDT/PSS (poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate)) conductive polymer, and wherein the antistatic layer has on at least a portion of a major surface thereof an ink receptive layer capable of receiving an organic solvent-based ink, wherein the ink receptive layer comprises a major component of a crosslinked urethane polymer and copolymers and blends thereof with acrylic polymers, and about 5% to about 20% by weight of an ink absorber selected from the group consisting of metal oxides and silicas.
