Abstract
In one aspect, the invention provides ink receptor compositions capable of receiving and fixing a water resistant image on a substrate without bleeding, feathering, or smudging. The ink receptor compositions comprise colloidal alumina; multivalent metal ion; hydrophilic binder; hydrophobic latex; surfactant; and optionally an image transfer aid. In other aspects, the invention provides methods of imaging substrates, ink receptor media, and ink receptor kits.

An ink receptor medium kit comprising:
- an image transfer medium;
- and
- an ink receptor composition comprising a mixture of:
- colloidal alumina;
- multivalent metal ion selected from the group consisting of metal ions from group IIA to VIA of the Periodic Table;
- hydrophilic binder that is at least partially soluble or swellable in deionized water;
- hydrophobic latex having a glass transition temperature of from about −60° C. to about 100° C. and a surface having an advancing contact angle with deionized water of greater than about 60 degrees when dried or cured;
- surfactant, wherein said surfactant is non-ionic, cationic, anionic, zwitterionic, or a combination of anionic and non-ionic surfactants;
- and
- optionally an image transfer aid, in a container.
