Abstract
An ink receptive substrate including an ink receptive layer configured to receive at least one inkjet ink. The ink receptive layer having a plurality of first silica particles and a plurality of second silica particles, wherein the average particle diameter of the first silica particles is different than the average particle diameter of the second silica particles. The ink receptive layer also having a first acrylic polymer and a second acrylic polymer, wherein the first acrylic polymer and second acrylic polymer are partially miscible. In one aspect, the includes ink receptive substrate includes a base layer configured to support the ink receptive layer and a high water capacity layer configured to reduce water accumulation in the ink receptive layer.
