The inkjet recording sheet substrate of the present invention comprises a cellulosic sheet support, e.g., paper, having on at least one surface thereof a base coating comprising pigment and binder. The preferred pigment component is a 50/50 mixture of kaolin clay and calcined clay, and the preferred binder component is polyvinyl acetate. This combination of binder and pigment has been found to possess a high absorption capacity for the vehicle of an inkjet ink and good compatibility with ink receptive top coatings applied over the base coat.
