摘要:
A cyan ink for ink-jet recording contains a coloring agent, water and a water soluble organic solvent. Different types of dyes are employed as the coloring agent. In particular, a dye represented by the general formula (1) is used together with at least one dye selected from the group consisting of a dye represented by the general formula (2), a dye represented by the general formula (3) and C. I. Direct Blue 86. In the formulas, Pc(Cu) is a copper phthalocyanine nucleus.
摘要:
New ink-jet printing inks provide red printed images with high-intensity fluorescence emission and are capable of printing images that can be used for high density bar code applications (2D bar codes) having high readability. The inks are aqueous and capable of producing machine-readable markings exhibiting fluorescence when exposed to fluorescent-exciting radiation. They exhibit a peak of fluorescence between about 500 nm and about 700 nm and a fluorescent strength of the ink diluted by 100 times of more than about 70 by excitation of ultraviolet radiation. The inks exhibit a peak of absorbance of between about 400 nm and about 600 nm, and an absorbance of the ink diluted by 100 times and measured in 1 mm cell of more than about 0.6. The preferred inks are characterized by a color of the ink diluted by 100 times with water and measured in 1 mm cell is t L*: about 80±10, a*: about 45±20, b*: about 20±35 and a color of the printed image of L*: about 65±10, a*: about 55±10, b*: about 5±20. Compositionally, the preferred inks are comprised of a dye selected from the group consisting of C.I. Acid Red 52, C.I. Acid Red 87 and C.I. Acid Red 92. In some preferred inks, the absorption coefficient to paper is between about 0 mL/m2sec1/2 and about 130 mL/m2sec1/2 by the measurement of the Bristow method.

摘要:
A photocopying system without using an intermediate film is disclosed. In this system, the photo-pressure sensitive sheet and an original are tightly overlapped on a photocopying stage. Scratching scars generated by friction therebetween can be avoided by drive means for changing a distance therebetween. Images on the reverse side of the original can be protected from being duplicated by changing a direction of a light beam. Figure/character images, as well as image trimming, can be arbitrarily photocopied by exposing to a light through display on liquid crystal panel.
摘要:
A cartridge case in which a microcapsule-carrying sheet to be used as an image recording medium is stored, is filled with a non-oxidative gas which makes it possible to store the microcapsule-carrying sheet for extended periods without affecting its performance. Nitrogen gas or inert gas such as neon, argon, helium, and xenon is suitable as the non-oxidative gas.
摘要:
A recording system including an exposing device for image-wise exposing a pressure-sensitive photosensitive medium according to source image information, so as to form thereon latent images, and a developing device for applying a pressure to the image-wise exposed photosensitive medium so as to cause a chemical reaction with a developer material, to thereby develop the latent images into visible images on a recording medium. The recording system further includes a coating device for applying the developer material to the recording medium.
摘要:
An image recording apparatus using a microcapsule carrying member and a developer member. The microcapsule carrying member includes a substrate and a plurality of microcapsules on the substrate, and each of the microcapsules includes a chromogenic material and a photo-curable material. The developer member includes a developer layer formed on a substrate. A pressure unit is provided for rupturing the microcapsules and reacting the developer material with the non-cured chromogenic material even upon light exposure. A calendering unit is provided at a position downstream of the pressure unit for calendering an imaging surface of the developer member.
摘要:
An ink set containing a water-based ink for ink jet recording and a treatment liquid. The water-based ink contains a phosphate group-modified self-dispersing pigment, water, and a water-soluble organic solvent. The treatment liquid contains a monovalent metal ion, water, and a water-soluble organic solvent.
摘要:
The present disclosure relates to an ink-jet ink set which, in spite of using a black ink including a black pigment, may form printed matter (e.g., images) with desirable fixability to glossy paper, color balance after fading (fading stability), and/or water resistance and/or ink-jet ink sets with desirable storage stability. An ink set may include a yellow dye ink including a yellow dye, a magenta dye ink including a magenta dye, a cyan dye ink including a cyan dye and a black ink. A black ink may include a black pigment, a yellow dye, a magenta dye and a cyan dye. A black ink may have a weight ratio of the amount of the black pigment to the total amount of the yellow dye, the magenta dye, and the cyan dye of from about 30/70 to less than about 70/30 (e.g., from about 30/70 to about 70 (but not inclusive of 70)/30).
