Abstract
A number of variations may include depositing, on a substrate comprising cellulose, an aqueous mixture comprising modified cellulose polymer molecules and organic acid molecules comprising at least two carboxyl acid groups; removing water from the mixture deposited on the substrate to provide a coating on the substrate; wherein the organic acid molecules have a melting point above ambient temperature, and wherein the organic acid molecules are cross-linkable with the modified cellulose polymer molecules and the cellulose at or above ambient temperatures.

A method comprising:
- depositing, on a substrate comprising cellulose, an aqueous mixture comprising a modified cellulose polymer molecules and organic acid molecules comprising at least two carboxyl acid groups;
- removing water from the mixture deposited on the substrate to provide a coating on the substrate;
- wherein the organic acid molecules have a melting point above ambient temperature, and wherein the organic acid molecules are cross-linkable with the modified cellulose polymer molecules and the cellulose at or above ambient temperatures.
A product comprising:
- a substrate having a cross-linked coating thereon, the substrate comprising cellulose, the cross-linked coating being the cross-linked reaction product of a modified cellulose polymer molecules, organic acid molecules, and the cellulose, wherein the organic acid molecules comprising at least two carboxyl acid.
A product comprising:
- an aqueous mixture comprising a modified cellulose polymer molecules and organic acid molecules comprising at least two carboxyl acid groups on a substrate comprising cellulose, and wherein the organic acid molecules have a melting point above ambient temperature, and wherein the organic acid molecules have a cross linking property with the modified cellulose polymer molecules and cellulose at or above the melting point of the organic acid molecules.
