Abstract
This invention provides printed and print receptive articles and processes for making such articles. The articles have a substrate coated with hydrophobic, ink receptive polymer composition characterized by a solvent resistant fraction of at least about 0.6 and a solvent absorbance capacity of at least about 300%.
Claims31
A printable article comprising a substrate coated with hydrophobic, ink receptive polymer composition characterized by a solvent resistant fraction of at least about 0.6 and a solvent absorbance capacity of at least about 300% wherein said hydrophobic, ink receptive polymer composition comprises a crosslinked amine functional polymer.
A printed article comprising a substrate coated with a layer of hydrophobic, ink receptive polymer composition characterized by a solvent resistant fraction of at least about 0.6 and a solvent absorbance capacity of at least about 300%, and an image formed on said layer by a non-aqueous solvent based ink wherein said hydrophobic, ink receptive polymer composition comprises a crosslinked amine functional polymer.
A process for preparing a printable article comprising:
- coating a substrate with a composition comprising a crosslinkable amine functional polymer and a crosslinking agent;
- and
- heating said coated substrate to a sufficient temperature to produce a crosslinked hydrophobic, ink receptive polymer layer on said substrate wherein said hydrophobic, ink receptive polymer layer is characterized by a solvent resistant fraction of at least about 0.6 and a solvent absorbance capacity of at least about 300%.
