Abstract

The present disclosure provides recording media and related methods. A recording media for printing can comprise a base paper and a backside extruded polyethylene layer on a side of the base paper. The backside extruded polyethylene layer can include a filler and an organic reagent admixed in the extruded polyethylene layer, wherein the filler and organic reagent are present in the backside extruded polyethylene layer in an amount of 20% by weight to 50% by weight based on the total weight of the backside extruded polyethylene layer.

First claim

What is claimed is:

1. A recording media for printing, comprising:
a base paper; and
a backside extruded polyethylene layer on a side of the base paper, the backside extruded polyethylene layer including a filler and an organic reagent admixed in the extruded polyethylene layer, wherein the filler and organic reagent are present in the backside extruded polyethylene layer in an amount of 20% by weight to 50% by weight based on the total weight of the backside extruded polyethylene layer,
wherein the organic reagent of the backside extruded polyethylene layer is selected from the group consisting of an organosilane reagent, monoalkoxy titanate, oxyacetate chelate titanate, quat titanate, quat zirconate, coordinate titanate, coordinate zirconate, neoalkoxy titanate, cycloheteroatom titanate, cycloheteroatom zirconate, neoalkoxy zirconate, and mixtures thereof.

2. The recording media of claim 1 , wherein a portion of filler and the organic reagent combine to form surface activated filler admixed in the backside extruded polyethylene layer.

3. The recording media of claim 1 , further comprising a frontside extruded polyethylene layer on a side of the base paper.

4. The recording media of claim 3 , wherein the frontside extruded polyethylene layer comprises a filler and an organic reagent admixed in the frontside extruded polyethylene layer, wherein a portion of filler and the organic reagent combine to form surface activated filler admixed in the frontside extruded polyethylene layer.

5. The recording media of claim 4 , further comprising an imaging layer coated on the frontside extruded polyethylene layer.

6. The recording media of claim 5 , further comprising an imaging layer coated on the backside extruded polyethylene layer.

7. The recording media of claim 3 , further comprising an imaging layer coated on the frontside extruded polyethylene layer.

8. The recording media of claim 3 , further comprising a curl control layer coated on the backside extruded polyethylene layer.

9. The recording media of claim 3 , wherein the backside extruded polyethylene layer is coated on a side of the base paper in an amount ranging from 10 gsm to 45 gsm and having a coating thickness ratio of backside extruded polyethylene layer to frontside extruded polyethylene layer ranging from 1.5:1 to 2:1.

10. The recording media of claim 3 , wherein the frontside extruded polyethylene layer and the backside extruded polyethylene layer independently comprise a polyethylene selected from the group of LDPE, HDPE, and mixtures thereof; and wherein the filler of the backside extruded polyethylene layer is selected from the group of calcium carbonate, zeolite, silica, talc, alumina, aluminum trihydrate (ATH), calcium silicate, kaolin, calcined clay, and combinations thereof.

11. The recording media of claim 3 , wherein the organic reagent is present in an amount of about 1% to 10% by weight based on the total weight of the filler and the organic reagent.

12. A method of coating a base paper, comprising
extruding polyethylene onto a side of the base paper forming a backside extruded polyethylene layer, wherein the backside extruded polyethylene layer includes a filler and an organic reagent admixed in the extruded polyethylene layer, wherein the filler and organic reagent are present in the backside extruded polyethylene layer in an amount of 20% by weight to 50% by weight based on the total weight of the backside extruded polyethylene layer,
wherein the organic reagent of the backside extruded polyethylene layer is selected from the group consisting of an organosilane reagent, monoalkoxy titanate, oxyacetate chelate titanate, quat titanate, quat zirconate, coordinate titanate, coordinate zirconate, neoalkoxy titanate, cycloheteroatom titanate, cycloheteroatom zirconate, neoalkoxy zirconate, and mixtures thereof.

13. The method of claim 12 , wherein the filler and organic reagent is admixed in the polyethylene during the extruding.

14. The method of claim 12 , wherein the filler and organic reagent is admixed in the polyethylene before the extruding.

15. The method of claim 12 , further comprising extruding polyethylene onto an opposite side of the base paper forming a frontside extruded polyethylene layer, wherein the frontside extruded polyethylene layer includes a filler and an organic reagent admixed in the frontside extruded polyethylene layer, wherein the filler and the organic reagent are present in the frontside extruded polyethylene layer in an amount of 20% by weight to 50% by weight based on the total weight of the frontside extruded polyethylene layer.
