Abstract
Disclosed is a recording sheet which comprises a substrate and a coating thereon comprising water and a surfactant capable of exhibiting a liquid crystalline phase in water at a temperature of about 25.degree. C. or higher, said coating containing the water and surfactant in relative concentrations such that upon addition of water to the coating, the surfactant undergoes a phase change, thereby increasing the viscosity of the coating. In one embodiment, the surfactant is in a lamellar liquid crystalline phase and, upon addition of water to the coating, the surfactant undergoes a phase change to a hexagonal liquid crystalline phase. Also disclosed are ink jet printing processes wherein an aqueous ink is applied to the aforementioned recording sheet.
