An ink for ink-jet recording includes: at least one of an azo dye having a specific structure; and at least one of a betaine surfactant and a nonionic surfactant, and an ink set includes the ink, and an ink-jet recording method used the ink.

The addition of a variety of additives to a soluble electroluminescent polymer in solution is used to improve the printability and performance of screen printed light-emitting polymer-based devices. Examples of such additives include transparent polymers, gel-retarders, high viscosity liquids, organic and inorganic salts, and oxide nanoparticles. The additives are used to control the viscosity of the electroluminescent polymer ink, to decrease the solvent evaporation rate, and to improve the ink consistency and working time. In addition, these additives can improve the charge injection and power efficiency of light emitting devices manufactured from the screen printable electroluminescent polymer ink.

Preparation of poly (etherester)n (I) comprises: reaction of a mono or polycarboxylic acid ester containing hydroxy group with an alkyleneoxide to form mono or polycarboxylicacid ester with one or more polyether chains (II) by ring opening; and either transesterification of (II) to give (I) with hydroxy groups; or reaction of (II) with mono or polycarboxylicacidester containing free hydroxy group to give (I) with ester; or hydrolyzation of (II) with mono or polycarboxylic acid containing free hydroxy group to give (I) with carboxylic acid. Preparation of poly (etherester)n (I) comprises: reaction of a mono or polycarboxylic acid ester containing hydroxy group of formula ((R-O-(C=O)-) m-R-a-(-OH) n) with alkyleneoxide to form mono or polycarboxylicacid ester with one or more polyether chains (II), by ring opening, where the alkylene oxyaddition takesplace optionally in the presence of di- or polyols and dicarboxylic acid esters; and either transesterification of (II) to give (I) with hydroxy groups, where the transesterification takes place optionally by the addition of di- or polyols, diol and dicarboxylic acids, dicarboxylic acid derivatives, monocarboxylic acid esters or monocarboxylic containing di- or polyols or hydroxy groups; or reaction of (II) with mono or polycarboxylicacidester containing free hydroxy group to give (I) with ester; or hydrolyzation of (II) with mono or polycarboxylic acid containing free hydroxy group to give (I) with carboxylic acid. R : monovalent aryl-, alkyl-, aralkyl-, alkenyl- or alkynyl- radical; and R-a : bivalent aryl-, alkyl-, aralkyl-, alkenyl- or alkynyl- radical. Provided that: if m is 1, then n is1; or if m is >= 2, then n is 1; or if n is >= 2, then m is1. Independent claims are included for: (1) a poly(etherester), which is prepared by the above procedure; and (2) use of (I) for the preparation of polyurethane materials.

Techniques for fabricating an inkjet printhead include providing a printhead substrate (100), fabricating a thinfilm structure (101) on the substrate, forming a break trench (124) in a surface region of the substrate in which a feed slot is to be formed, and subsequently abrasively machining the substrate through the break trench to form the feed slot (126). The break trench can be formed by an etch process, prior to applying a barrier layer (112) to the thinfilm structure in a preferred embodiment.

The present invention is drawn to a print medium and a method of preparing the same. The print medium can include a media substrate, a porous ink-absorbing layer coated on the media substrate, and a porous ink-receiving layer coated on the porous ink-absorbing layer. The porous ink-absorbing layer can include semi-metal oxide or metal oxide particulates and a first binder, and the porous ink-receiving layer can include organosilane-functionalized semi-metal oxide or metal oxide particulates and a second binder.
