A recording medium comprising on a base material an ink-receiving layer containing an alumina hydrate, said ink-receiving layer being formed by applying a coating liquid containing said alumina hydrate to said base material followed by drying to form a layer to be said ink-receiving layer, swelling said layer to be said ink-receiving layer again, and pressing the swollen layer to a heated mirror-finish drum for drying, the glossiness of the surface of the recording medium on the side of the ink-receiving layer as measured at 20&deg; being 20% or more.

Recording medium, manufacturing process thereof and image forming method using the medium

Provided is a recording medium provided with an ink-receiving layer on at least one surface of a substrate, wherein said ink-receiving layer is composed of a porous layer comprising pigment particles and mutually fused thermoplastic resin particles.

Recording medium, image forming process using the same, and process for the preparation of the same

Recording medium, ink-jet recording therewith, and process for production thereof

Provided is a fine powder material for forming an ink-receiving layer on a recording medium, wherein a pore radius maximum exists within a range of from 90 to 120 &angst; in a pore radius distribution of said fine powder material and wherein a total volume of pores having radii not exceeding 50 &angst; is not more than 6.0% of a volume of all pores.

Fine powder material for forming in-receiving layer, manufacturing method thereof, recording medium making use of the fine powder material and image forming method using the recording medium

There is provided a recording medium comprising a substrate and an ink-receiving layer containing alumina hydrate formed thereon, wherein the alumina hydrate is present unoriented in the ink-receiving layer and a diffraction intensity fluctuation &dgr; in a diffraction pattern is not more than 5%, when irradiating an electron beam to a cross section of the ink-receiving layer.

Recording medium and recording method for using the same

Disclosed herein is a recording medium comprising a base material and a porous surface layer containing particles of a thermoplastic resin, wherein the breadth of the particle size distribution of the particles of the thermoplastic resin is within 3.sigma., and the proportion of particles having a particle size at most a fifth of the average particle size of the particles of the thermoplastic resin is 10% or lower.

Recording medium and ink-jet recording process using the recording medium

A process for producing a magnetic recording medium includes coating a nonmagnetic substrate with a magnetic paint and applying a rotating magnetic field for orientation to the raw fabric with magnetic paint in a yet unsolidified state on the substrate, in which a magnetic field is applied to the above raw fabric so that the magnetic lines of force may pass from the back face to the front surface or from the front surface to the back surface of the raw fabric before application of the rotating magnetic field for orientation, thereby effecting preliminary orientation.

Process for producing magnetic recording medium

A process for preparing a magnetic recording medium by coating a magnetic coating material on a non-magnetic support and then drying the above magnetic coating material, which comprises imparting a magnetic field to said magnetic coating material with a magnet which rotates with the rotational surface at an angle of 5.degree. to 30.degree. relative to the surface of said support prior to drying of said magnetic coating material on said support.
