Inkjet recording element comprising particles and polymers
First Claim
1. An inkjet recording element comprising a support having thereon at least one image-receiving layer, said inkjet recording element containing colloidal particles having a charged or chargeable surface and having associated therewith at least two water-soluble polymers having ionised or ionisable groups thereon, wherein one of those polymers has ionised or ionisable groups of opposite charge to that of the surface of the colloidal particles and another of those polymers has ionised or ionisable groups the same as that of the surface of the colloidal particles.

Abstract
The invention provides an inkjet recording element comprising a support having thereon an image-receiving layer, said inkjet recording element containing colloidal particles having a charged or chargeable surface and having associated therewith at least two polymers having ionised or ionisable groups thereon, wherein one of those polymers has ionised or ionisable groups of opposite charge to that of the surface of the colloidal particles and another of those polymers has ionised or ionisable groups the same as that of the surface of the colloidal particles. When printed with ink the element can impart good image stability, has a short dry time, can give any required gloss, provides good optical density and is suitable for use with a wide range of inks.
