Abstract
A process including providing a paper substrate; disposing a water soluble precoat composition onto all or a portion of the paper substrate to provide a treated paper; applying an image onto the treated paper using a toner or an aqueous ink to provide an imaged paper; wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate; and wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.
Claims23
A process consisting of:
- providing a paper substrate;
- disposing a water soluble precoat composition onto a portion of the paper substrate to provide a treated paper;
- applying an image onto the water soluble precoat composition using a toner or an aqueous ink to provide an imaged paper;
- wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate;
- and
- wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate.
A process consisting of:
- providing a paper substrate;
- disposing a water soluble precoat composition onto a portion of the paper substrate to provide a treated paper;
- wherein the water soluble precoat composition comprises polyvinyl alcohol;
- applying an image onto the water soluble precoat composition using a toner or an aqueous ink to provide an imaged paper;
- wherein the water soluble precoat composition forms a temporary barrier between the toner or aqueous ink and the paper substrate;
- wherein, during a paper pulping process, the water soluble precoat composition dissolves thereby releasing the toner or aqueous ink from the paper substrate;
- and
- wherein the paper pulping process comprises agitating the imaged paper with only water without other chemicals to provide pieces of paper pulp.
