Patent ID: 7232214

Claim:
A method of inkjet printing comprising applying an ink jet ink drop having a viscosity of about 2.5 to about 8.5 cP and a surface tension of about 25 to 45 dyne/cm to the surface of porous ink jet recording medium comprising a support having thereon an image-receiving layer, said image-receiving layer containing: a) from about 20 to about 50% by volume of or inorganic or organic particles, said inorganic or organic particles having a particle size of from about 0.01 μm to about 0.1 μm; b) from about 25 to about 70% by volume of a polymeric binder; and c) up to about 10% by volume of a cross-linking agent; whereby the diameter of said ink jet ink dot is increased relative to that which would have been obtained if said image-receiving layer had greater than about 50% by volume of said inorganic or organic particles, wherein the dot gain is 2.5 to 15.
