Patent ID: 8133556

Claim:
A two-layer receiver coating comprising: A. A base layer comprising: 1. First pigment particles having (a) a number average particle size of 3-25 microns (μm), and (b) at least one of (i) an oil absorption value of at least 150 g oil/100 particles, and (ii) a pore volume of at least about 1.2 cubic centimeters per gram (cm 3 /g); and 2. Water-insoluble binder resin having a surface energy greater than 40 dyne per centimeter (dyn/cm); the first pigment particles and water-insoluble binder resin present at a weight ratio of 0.75 to 2; and B. An imaging layer comprising: 1. Second pigment particles having (a) a number average particle size of 0.01-4 (μm) aggregated to form an inter-particle region of submicron pores, and (b) a pore volume of 0.4 to 2.2 cm 3 /g; and 2. Water-insoluble binder resin having a surface energy greater than 40 (dyn/cm); the second pigment particles and water-insoluble binder resin present at a weight ratio of 0.75 to 2.
