Colorant mixtures

The invention relates to a process for printing cellulose textile fibre material or cellulose/polyester mixed textile fibre material, characterised in that the fibre material is treated with a printing paste or printing ink containing a disperse dye of the formula whereinR-Rare each independently of the other hydrogen, halogen, C-C-alkyl or C-C-alkoxy,Rdenotes hydrogen, C-C-alkyl or a group of the formula &#x2014;SO&#x2014;NRR,wherein Rand Reach independently of the other denote hydrogen,C-C-alkyl which is unsubstituted or substituted by hydroxy, halogen, C-C-alkoxy or C-Caryl, orC-Caralkyl which is unsubstituted or substituted by hydroxy, C-Calkyl, C-Calkoxy or halogen,Rrepresents hydrogen, C-C-alkyl or a radical of the formula wherein R-Rare as defined above.

Process for printing cellulose containing textile fibre material

A method for producing infra-red inert substrates, including molded polymeric articles, films, fibers and coatings and other organic and inorganic materials, by incorporating into the substrate or onto the surface of the substrate an effective amount of a dispersed bis-oxodihydroindolylen-benzodifuranone colorant. The thus obtained, also claimed substrates so produced are reflective and transparent to much of the near infra red radiation not reflected. There are multiple applications for cases of devices comprising electronic components, outdoor construction elements, outdoor furniture, automotive, marine or aerospace parts, laminates, artificial leather or textile materials, as well as in polychrome printing processes and optical fibers. The thus obtained substrates can also be subjected to laser welding. New bis-oxo-dihydroindolylen-benzodifuranone compounds are also claimed.

NIR-inert substrates comprising bis-oxodihydroindolylen-benzodifuranones

A colorant composition comprising in a weight ratio of from 99:1 to 10:90, a pigment of average particle size from 10 to 200 nm and a compound of the formula 

Transparent colourants and colourant compositions, and their use

The invention relates to a process for enhancing the contrast of color filters comprising &#x3b1; copper phthalocyanine or &#x3b5; copper phthalocyanine, wherein a 1,4-diamino-anthraquinone dye or 1,9-annellated derivative thereof, of which the most bathochromic solution absorption peak in the visible spectrum is at from 575 to 615 nm, preferably at from 585 to 605 nm (as compared with around 630 nm for usual 1,4-diamino-anthraquinone dyes or 1,9-annellated derivatives thereof) is used in combination with &#x3b1; copper phthalocyanine or &#x3b5; copper phthalocyanine. Also claimed are color filters comprising such 1,4-diamino-anthraquinone dyes or 1,9-annellated derivatives thereof, as well as a novel compound of Formula (II), wherein Ris halogen, phenyl, benzyl or C-Calkyl and Ris H, Ris H and Ris C-Calkyl, or Rand Rare both H; Ris H, halogen, C-Calkyl or SONRR; R, Rand Rare each independently from the others halogen or C-Calkyl; and Ris independently from RSONRR, with the proviso that at least one of Rand Ris SONRR, and two radicals of Formula (II) can optionally be linked together via a direct bond or a group &#x2014;O&#x2014;, &#x2014;S&#x2014;, &#x2014;NR&#x2014;, &#x2014;CO&#x2014;, &#x2014;CO&#x2014;, &#x2014;CONR&#x2014; or &#x2014;CO&#x2014; connecting together each a substituent R, R, R, R, R, Rand Rfrom both radicals of formula (II). 

Blue colour filters with enhanced contrast

A process for printing flat substrates, in which the said substrate is printed with an ink composition including (a) a basic dye together with (b) an aliphatic carboxylic acid having at least four carbon atoms, (d) a binder resin, and water, yields water-resistant prints having a high depth of shade and high chroma.

Process for printing an aqueous ink composition

A process for printing flat substrate, in which the said substrate is printed with ink composition including a) a basic dye together with b) an aliphatic carboxylic acid having 4&#x2013;24 carbon atoms, c) a pigment, d) a binder resin and water, yields water-resistant prints having a high depth of shade and high chroma.

Process for printing using aqueous ink composition

The invention relates to an ink composition containing (a) a compound of formula (I), L&#x2212;Ln(Ch)(I), wherein Ln represents a lanthanide, CHis a negatively charged ligand containing at least one UV absorbing double bond, n denotes 3 or 4, m denotes a number from 1 to 4, in case n is 3, m denotes a number from 1 to 4 and L is a neutral monodentate or polydentate nitrogen-, oxygen- or sulfur-containing UV absorbing ligand with the exception of 2,2'-bipyridyl or, in case n is 4, m denotes 1 and L is a single-charged cation; and (b) a liquid ink carrier, which can be used for applying hidden mark on objects which can only be revealed under UV exposure.

Ink compositions containing lanthanide complexes

The invention pertains to the field of green color filters and LCDs. It has been found that pigments with surprisingly improved coloristic, chemical and physical properties are obtained by salt-kneading a halogenated phthalocyanine pigment together with a yellow pigment of the disazo condensation, barbituric acid or azoquinolone series. The process takes place in the presence of an organic liquid and in the absence of binder or optionally in the presence of a relatively small amount of binder. Claimed are the process itself as well as the green pigment composition obtained by the process and compositions comprising it.

Process for making green pigment compositions useful for color filters and LCD's

The present application relates to a process for the manufacture of pigmented vitreous materials, as well as to pigmented vitreous materials, characterized by the use of soluble pigment precursors and preferably the absence of significant amounts of dispersants. These pigmented vitreous materials can be used as colored materials for any known purposes. Soluble pigment precursors comprising a partial structureare also claimed, wherein Xis an aromatic or heteroaromatic ring, B is hydrogen or a group of the formulabut at least one group B is not hydrogen, and L is a solubilizing group.
