Dependent claims

A wiping product comprising:

a base sheet having a first side and a second side, wherein said base sheet comprises from 0 to 49 percent by weight of cellulosic materials;
a coating derived from an aqueous polyolefin dispersion, wherein said coating is present on at least the first side of the sheet, and wherein said coating has a thickness in the range of from 0.01 microns to 10 microns, and wherein said coating comprises an interconnected network with openings or said coating comprises discrete areas, and wherein said polyolefin dispersion comprises (a) a thermoplastic polymer comprising an alpha olefin interpolymer of ethylene or propylene and at least one comonomer, each comonomer being selected from the group consisting of octene, heptene, hexene, decene, and dodecene;
(b) a dispersing agent, wherein said dispersing agent is a polar polymer;
and (c) water, and wherein said aqueous polyolefin dispersion has an average particle size in the range of from 0.05μ to 5 μm and a pH in a range of from 7 to 11, and wherein said dispersion comprises more than 25 percent by weight of water;
and
wherein the first side of the base sheet has a Cleaning Test Value of greater than about 5 mg.
