摘要:
An ink composition for ink jet recording is provided which can satisfy property requirements of quality of print, drying property of print, clogging resistance, water resistance, storage stability, and nonattacking on members constituting an ink passage, such as a printing head. The ink composition for ink jet recording comprises a dye represented by the following formula (I), glycerin, pyrrolidone, a monohydric lower alcohol, a tri(hydroxyalkyl)amine, and water: ##STR1## wherein R.sup.1 represents phenyl or naphthyl substituted by a group selected from hydroxyl, --NH.sub.2, --SO.sub.3 M and --COOM, R.sup.2 represents carboxyalkyl, alkoxyalkyl, phenyl, or alkanoyl, R.sup.3, R.sup.4, and R.sup.5 represent hydrogen or --SO.sub.3 M.

A yellow ink composition, a magenta ink composition and cyan ink composition and a solvent system which are suitable for a color ink jet printing method are disclosed. These ink compositions can realize ideal color tones without limitation of properties of paper. Moreover, these ink compositions are excellent in intermittent jetting stability. The color ink jet printing method is also disclosed. In this method, ink compositions are overprinted to mix colors. Colors obtained by the color mixing have an ideal color tone.
摘要:
Objects of the present invention include providing composite metallic thin filmy particles for conductive inks and a conductive ink, both allowing the production of highly conductive substrates with simpler equipment and at a lower cost, providing a method for making such a conductive substrate, and providing such a conductive substrate.The present invention includes Step 1 for coating a surface of a base material sheet with a composite metallic thin film layer that contains at least one of a resin layer and a wax layer and at least one of a metal layer and a metal compound layer and Step 2 for removing the composite metallic thin film layer from the sheet. The resultant composite metallic thin filmy particles and conductive ink can be used in a conductive substrate producing apparatus, formed into a pattern on the conductive substrate by screen printing, an ink jet method, or some other liquid-based process.

A yellow ink composition includes C.I. Pigment Yellow and C.I. Pigment Yellow 74 as coloring agents. The ratio of a C.I. Pigment Yellow 185 content (percent by weight) to a C.I. Pigment Yellow 74 content (percent by weight) is in the range of 0.5 to 15. The yellow ink composition has a C.I. Pigment Yellow 185 content of 10% to 20% by weight and a C.I. Pigment Yellow 74 content of 10% to 20% by weight.

摘要:
A method for manufacturing luminous element particles, comprising: forming a luminous element layer, containing a release layer and luminous organic compound layer, on at least one side of a base material; and micro-fragmenting the luminous element layer after separating the same from the one side of the base material.
摘要:
The present invention provides an ink jet recording head for use in an ink jet recording device, wherein a water-repellent layer (21) comprising a homogeneous layer of a fluoropolymer is formed on the surface of a nozzle for jetting an ink. This water-repellent layer can be formed as a dense, homogeneous layer through the use of a solvent-soluble fluoropolymer, which enables an ink jet recording head excellent in the water-repellent property, the persistence of the water repellency and the durability.
