Abstract: A multi-layer optical recording medium includes a light transmissive intermediate layer. This intermediate layer is formed by at least two times of laminating steps. The recording medium has smaller bending, and the intermediate layer has uniform thickness.

Abstract: There is provided an image-receiving sheet for recording with dye or ink which comprises a base sheet and a resin layer comprising a powdery coating composition which contains a resin component as a dye- or ink-receiving layer on the base sheet. There is further provided a process for the production of such an image-receiving sheet which comprises dry-coating a powdery coating composition which contains a resin component on a base sheet by an electrostatic spraying process, heating, melting and fixing the powdery coating composition thereon to form a resin layer as a dye- or ink-receiving layer.

Abstract: A coating device is provided for coating particles of a particulate coating composite consisting of particles of resin and particles of an offset preventing agent having a higher melting point than that of the resin on a paper substrate. A pair of rollers are provided to be contacted with each other for fixing the particulate coating composite on one of surfaces of the paper substrate. The particulate coating composite and the paper substrate are heated from one of the rollers, The heating temperature is set to a value which is higher than a melting point of said resin and lower than a melting point of said offset preventing agent.

Abstract: An apparatus for coating fine particles to produce a thermal transfer image receiving sheet having: a base material supply section 1 for supplying a paper base material; a coating storage section 21 for storing a coating including white fine particles; a development section 2 having a sleeve 22 for holding the coating supplied from the coating storage section 21, a blade 23 for controlling a thickness of the coating held by the sleeve 22, a charge drum 24 having a photosensitive material for absorbing the coating in a dispersed manner from the sleeve 22, and a dot latent image forming device 25 for forming a dispersed dot latent image on the charge drum 24 by irradiating a laser beam to the charge drum 24 to absorb the coating on the charge drum 24 in said dispersed manner on the basis of the dispersed dot latent image; a transfer section 3 for electrostatically transferring the coating absorbed by the charge drum 24 onto the paper base material in the dispersed manner; a fixing section 4 having a heat roller

By using the apparatus 100, the thermal transfer image receiving sheet S on which a high quality image can be formed, is produced easily.

Abstract: There is provided a method for forming an image-receiving sheet for sublimation thermal transfer recording, in which a photoreceptor is partly or wholly charged as it is rotated, while the powdery coating composition is charged oppositely to the photoreceptor and is then adhered to the surface of the photoreceptor, and thereafter the composition is transferred onto the base sheet, and then heated, melted and fixed, thereby to form a continuous film of the receiving layer on the base sheet.There is further provided a white, powdery coating composition for use for the production of such an image-receiving sheet as above, which comprises a resin component, a white colorant, and a cured product of reaction-curable silicone oils and is characterized in that the composition comprises, as the resin component, from 70 to 95% by weight of a resin mixture comprising from 50 to 90% by weight of a saturated polyester resin having an acid value of from 1.0 to 20 mg KOH/g and a glass transition point of from 50.degree.

Abstract: A color sheet comprising; a flexible substrate or film; and a dye layer formed on the substrate including a sublimating dye of yellow, magenta or cyan and a near infrared absorbing pigment with a near infrared absorption without a substantial visible absorption.A color transfer method comprises the steps of: preparing a color sheet above mentioned; abutting the dye layer of the color sheet onto an image receiving sheet to be printed; and irradiating an optical laser beam to the dye layer, the laser beam having a wavelength in the near infrared region absorbed by the near infrared absorbing pigment, whereby a light energy absorbed by the near infrared absorbing pigment is converted into a heat energy thereby sublimating the sublimating dye and transferring the sublimated dye onto the image receiving sheet arranged so as to face the dye layer.As a result, a recording speed and a resolution are remarkably improved with the color sheet and the color transfer method using it.
