Abstract
A method of making an inklet recording sheet having pigment-binder gradient in the ink-receiving layer is provided. The method includes providing a support and forming an inkjet receiver layer over the support. The receiver layer has a lower-most portion over the support and an upper-most layer. The inkjet receiver layer is formed with a gradient in ration of binder to pigment ranging from more binder and less pigment in the lower-most portion and less binder and more pigment in the upper-most portion.
