摘要:
A substrate for ink jet head which includes an electrothermal converting body provided with a heat generating resistor (103) capable of generating, upon energization, heat energy to be directly applied to ink on a heat acting face (109) whereby discharging said ink, wherein said heat generating resistor (103) is composed of a material consisting essentially of Pt and Ta at specific composition ratios.
摘要:
A recording medium is provided which comprises an ink-transporting layer and an ink-retaining layer, the ink-transporting layer being chiefly comprised of particles and a binder, wherein d ≧ 0.1 µm when an average value of primary particle diameter of the particles is assumed as d, and the volume of the particles whose particle diameter (x) is included in the range of d/2 ≦ x ≦ 2d is in a proportion of 90 % or more of the whole particles. An ink jet recording process employing the above-mentioned recording medium is also provided.

摘要:
An ink-jet recording process is provided which comprises applying inks to a recording medium having at least an ink-transporting layer and an ink-retaining layer, from the ink-transporting layer side of said recording medium, and thereby forming with a plurality of ink dots a unicolored area observable from the ink-retaining layer side, the dots being formed respectively by aplication of at least two ink droplets in superposition. A mixedly colored area can be formed in a similar manner.
