Disclosed an ink jet printing paper and a coating color used in preparing the paper, and associated methods for manufacturing the paper and its coating. The coating comprises the following components as raw materials: an anionic pigment, an adhesive and a cationic polymer, wherein the adhesive comprises a silane-modified polyvinyl alcohol. In the inventive ink jet printing paper coating, the raw material cost can be relatively low, the coating color solids content can reach 50% in many embodiments, and the coating can have a good water-retaining property. It can be suitable for large-scale production. In ink jet printing, it can give clear images with high color density, and can meet demanding requirements for high speed commercial ink jet printing.
