Title: Ferromagnetic powder for coating and magnetic recording medium coated with said powder
Inventor: HIRANO TOSHIMASA
IPC: G11B5/73
Filed: 1985-04-19
Abstract: PURPOSE:To improve the wear resistance of a coating type magnetic recording medium by dispersing pulverous ferromagnetic powder into a binder by using a dispersant consisting of a specific component compsn. and having amino groups and adding polyisocyanate thereto. CONSTITUTION:A material having 2 primary or secondary amino groups into one molecule as the dispersant and polyisocyanate is added to the powder. Part of the amino groups in the dispersant are absorbed to the pulverous ferromagnetic powder and therefore the dispersibility thereof is improved; in addition the other amino acid groups which are not adsorbed on the magnetic powder generates a urea dond by reacting with the polyisocyanate and therefore the basicity which is the cause for the deterioration of the coated film is weakened. The leaching of the dispersant to the coated film surface is further prevented and the pulverous ferromagnetic powder is securely accelerated by crosslinking of the polyisocyanate group and binder resin The dispersant is expressed by the formula. R1, R2, R3, R4 and R5 in the above-mentioned formula denote an optional hydrocarbon. The water resistance is thus improved.

Title: Ink jet recording device and recording method
Inventor: MIYAKE NOBUTAKA
IPC: C09D11/00
Filed: 1990-03-31
Abstract: PURPOSE:To eliminate feathering on paper, which is caused by discharged ink droplets, and form an image at high density by discharging ink onto a drum, around which a PET film is wound, to perform recording, and transferring the image to recording paper after evaporating moisture contained in the ink with the aid of a dryer to increase the density of dyes. CONSTITUTION:Ink is discharged onto a drum 2 by an ink jet head 1 according to image printing information, and recording is performed. In order to prevent recesses and protrusions on paper that may be caused after printing, the distance between the ink jet head 1 and the drum 2 can be made equal to, or closer than a distance between a head and paper as seen in a conventional system, whereby printing accuracy can be enhanced. Liquid droplets discharged and recorded do not penetrate into a film due to the water-repellent effect of a PET film on the drum 2 but remain to stay on the surface of the film. The liquid droplets stayed on the surface are forcibly dried by a dryer 3 while keeping a uniform round shape and a small size, so that the density of dyes in the ink droplets is greatly increased. The ink droplets, in which the density of dyes has been increased, are transferred to recording paper 5 by allowing the drum 2 to contact a roller 4 under pressure.
