ABSTRACT:
The present invention relates to a print medium with improved resistance to airfade. The print medium is coated with a high molecular weight additive having low volatility. The high molecular weight additive is a monomeric or oligomeric compound that has a molecular weight of greater than approximately 1000. The high molecular weight additive is a hindered amine light stabilizer or a fixative. The present invention also relates to a method of producing a print medium with improved airfastness. The method comprises coating a print medium with a high molecular weight additive having low volatility. An image is then printed on the coated print medium and subjected to at least one atmospheric gas. The airfastness of the printed image is measured and compared to the airfastness of an image printed on an uncoated print medium.
