Abstract
A platelet-type zirconium phosphate, which has a P—OH group contained in a structure thereof, and has a crystalline peak at a 2θ value of 11.6±2 degrees and no crystalline peak at a 2θ value of less than 11.6±2 degrees in X-ray diffraction analysis, is provided. The platelet-type zirconium phosphate has a platelet-type structure and can be uniformly dispersed at a nanoscale level in a coating film to exhibit excellent surface gloss and barrier capability. Also, the platelet-type zirconium phosphate can exhibit excellent corrosion resistance due to the presence of the P—OH group on a surface thereof, and can be dispersed not only in an aqueous solution but also in an organic solvent.
