Composition and ink receiving system incorporating the composition
View Patent ↗A composition includes an alkenyl succinic anhydride sizing agent or an alkyl ketene dimer sizing agent. The alkenyl succinic anhydride sizing agent is present in an amount ranging from about 1.0 pounds per ton to about 4.0 pounds per ton. The alkyl ketene dimer sizing agent is present in an amount ranging from about 2.0 pounds per ton to about 10.0 pounds per ton. A metallic salt is also incorporated in the composition.
1. A paper, comprising:
an alkenyl succinic anhydride internal sizing agent in an amount ranging from about 1.0 pounds per ton to about 4.0 pounds per ton of paper; and
a metallic salt in an amount ranging from about 20 pounds to about 25 pounds per ton of the paper;
wherein the alkenyl succinic anhydride internal sizing agent is incorporated into the paper during a wet end operation of papermaking, and wherein the paper exhibits an ink transferability of equal to or less than 13% and a black optical density of greater than about 1.5;
and wherein the metallic salt is incorporated into the paper during a wet end operation of papermaking.
2. The paper as defined in claim 1 wherein the internal sizing agent and the metallic salt are adapted to provide the paper with a total sizing less than about 70 as measured by a Hercules Sizing Test.
3. The paper as defined in claim 1 wherein the paper is adapted to have indicia formed thereon with color pigmented ink, the indicia having substantially increased lightfastness and substantially increased color gamut.
4. The paper as defined in claim 1 wherein the paper is selected from plain paper or photopaper.
5. The paper as defined in claim 3 wherein the color pigmented ink is selected from a disazo yellow pigment class, a bis-acetoacetarylide yellow pigment class, and combinations thereof.
6. The paper as defined in claim 3 wherein the color pigmented ink is selected from yellow ink 93 , yellow ink 128 , yellow ink 155 , and combinations thereof.
7. The paper as defined in claim 1 wherein the internal sizing agent and the metallic salt are adapted to provide the paper with a total sizing less than about 30 as measured by a Hercules Sizing Test.
8. The paper as defined in claim 1 wherein the paper is adapted to have indicia formed thereon with black pigment ink having a binder therein, the indicia having substantially increased optical density and substantially decreased drytime.
9. The paper as defined in claim 1 wherein the metallic salt is selected from calcium chloride, magnesium chloride, aluminum chloride, beryllium chloride, calcium nitrate, magnesium nitrate, aluminum nitrate, beryllium nitrate, and combinations thereof.
10. The paper as defined in claim 1 wherein the internal sizing agent and the metallic salt are each soluble in an aqueous medium at a pH ranging from about 4 to about 10.
11. The paper as defined in claim 10 wherein the internal sizing agent and the metallic salt are each soluble in an aqueous medium at a pH ranging from about 4 to about 6.5.
12. The paper as defined in claim 1 wherein the alkenyl succinic anhydride internal sizing agent is present in an amount ranging from about 1.2 pounds per ton to about 1.8 pounds per ton of paper.
13. A method for using the paper of claim 1 , the method comprising jetting, via an inkjet printer, pigmented color ink on a surface of the paper to form an indicia.
14. A method for using the paper of claim 1 , the method comprising jetting, via an inkjet printer, black pigment ink having a binder therein on a surface of the paper to form an indicia, a combination of the black pigment ink and the paper is adapted to form indicia having substantially increased optical density and substantially decreased drytime.
