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 disazo dye composition comprising at least a disazo dye represented by the formula (I) and a disazo dye represented by the formula (II): ##STR1## (wherein X and Y indicate an alkoxy group having 1 to 4 carbon atoms, and M indicates hydrogen or a cation selected from the group consisting of, alkaline metal, NH.sub.4, alkyl-substituted ammonium, alkanolammonium, morpholinium and piperidinium), wherein, when the disazo dye composition is analyzed by liquid chromatography, the area ratio of the peak area (Sp) of the disazo dye represented by the formula (I) to the peak area (Sc) of the disazo dye represented by the formula (II), that is Sp:Sc is from 1:0.4 to 1:2.4. This disazo dye composition provides a high quality image, rapid ink fixing and the like even on the plain paper.
摘要:
An ink composition capable of offering a combination of a high-quality image with a waterfast image is provided. More specifically, an ink composition is provided which, by virtue of a combination of particular dyes, can faithfully reproduce black color, realize a high-quality image (a sharp image having a high optical density and free from bleed) also on plain paper and, at the same time, offer rapid ink fixation and waterfastness and lightfastness of the printed image. Dyes represented by the following formula (I) are used as a fundamental dye and further combined with a plurality of dyes to constitute the ink composition: ##STR1## wherein R.sup.1 represents --PO(OM).sub.2 or --COOM, X and Y each independently represent an alkoxy and M represents a cation of a group selected from the group consisting of a hydrogen atom, an alkali metal, ammonia, and an organic amine.

A yellow ink composition and a magenta ink composition are provided which have good properties satisfying requirements for a color ink jet recording ink, particularly a requirement that the color ink composition is less likely to cause clogging of nozzles, and can realize a printed image having excellent tone, waterfastness, storage stability, and lightfastness. Further, a color ink set comprising the above ink compositions in combination with a particular cyan ink composition and a particular black ink composition are also provided. A yellow ink composition comprising a dye represented by the following formula (XI) in combination with a dye represented by the following formula (XII) is a fundamental color ink composition: ##STR1## wherein R.sup.101 and R.sup.102 represent phenyl or naphthyl substituted by a hydroxyl group, --SO.sub.3 M, or --COOM.
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.
