Abstract
This specification describes a composition for coating on a substrate, such as paper, useful for inkjet printing with ink having an anionic dye. The coating comprises a cationic binder and preferably pigment. The binder may be made of latex forming cationic biopolymer particles, for example made from cationic starch. Cationic biopolymer polymers are used as a cationic fixative. Optionally, a salt with a polyvalent metal ion may be added top the composition. With this addition, the substrate is also suitable for printing with dispersed pigment based inkjet ink.
