摘要: A magnetic powder containing MnBi, in which an average particle size of the magnetic powder is from 0.1 .mu.m to 20 .mu.m; a coercive force is from 3000 to 15,000 Oe at 300 K. and 50 to 1000 Oe at 80 K. when measured with applying a magnetic field of 16 KOe; an amount of magnetization is from 20 emu/g to 60 emu/g when measured at 300 K. with applying a magnetic field of 16 KOe; a degree of decrease of an amount of magnetization is 40% or less after being maintained in an atmosphere of 60.degree. C. and 90% RH for 7 days; and a content of metal bismuth (Bi) satisfies the following equation: Metal Bi/(MnBi+metal Bi)

摘要: An ink jet-printing medium comprising a substrate and an ink-receptive layer which has at least one layer and is formed on at least one major surface of the substrate, in which at least one layer of the ink-receptive layer contains fibrous fine powder as a pigment in an amount of at least 20% by weight of the total weight of the whole pigment contained in the layer which contains the fibrous fine powder. This medium can be produced at a low cost and has high printing quality while suppressing the discoloration or fading of the prints.
