PURPOSE:To maintain uniformity of an image and obtain images with favorable quality, by a method wherein a paper having a specified basis weight and a specified sizing degree and coated with a water base coating material is used as an ink jet recording material, and an ink having a specified viscosity is used. CONSTITUTION:A paper having a basis weight of 50-90g/m<2>, a sizing degree of 5-100sec and a thickness of 60-100mum is used as a base, which is coated with a known water base coating material to produce the recording material. On the other hand, an ink comprises a recording agent, e.g., a dye, and a liquid medium component, which is a mixture of water and a water-soluble organic solvent such that the viscosity of the ink is not higher than 25cP, preferably, not higher than 15cP. The organic solvent is preferably a polyhydric alcohol such as diethylene glycol or an ether thereof. The specified recording material and the specified ink are used to record by an ink jet recording of the electrostatic attraction type, the ultrasonic vibration type or the like. |
