摘要:
The present invention consists of a thickener particularly useful for thickening print compositions containing inks, dyes and/or pigments for application to textile. In particular, the thickening composition is comprised of at least three components, namely, vegetable oil, polyacrylic acid polymer/copolymer, an alkali material, and optional components such as an antioxidant. The vegetable oil can contain up to 50% by weight mineral oil. The polyacrylic acid can be a polymer or copolymer. The optional antioxidant is typically an organic compound and is employed to retard or prevent deterioration of the vegetable oil. Lastly, the alkali material is employed to help gel the polyacrylic acid. The thickener composition contains about 25 to about 75% by weight vegetable oil with or without mineral oil, from about 20 to 70% by weight polyacrylic acid or acrylic copolymer, from about 3 to 25% by weight alkali material, and optionally from about 0.5 to 3% by weight antioxidant wherein the total comprises 100%. The composition of the present invention is particularly useful in compositions having printing inks, dyes or pigments used in textile applications. It is contemplated that approximately 1 to 7% by weight of the thickener composition is employed in the ink, dye or pigment composition.
摘要:
The invention concerns dyeing formulations consisting of the following elements: a) at least a dye selected from the group comprising hardly water-soluble dyes a1) and water-soluble dyes a2), b) water, c) in the case of hardly water-soluble dyes a1), at least a dispersant and d) at least a compound of formula (I), wherein the variables are defined as follows: R1, R2 are selected independently of each other from the group consisting of hydrogen, C1-C4 alkyl, CH2-O-R3, R3 representing hydrogen or C1-C4 alkyl.
摘要:
A light-stable colored composition which includes a colorant and a radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth radiation, to be mutable. The radiation transorber also imparts light-stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light.
摘要:
A method of dehydrating a tertiary alcohol comprising reacting the tertiary alcohol in a non-aqueous non-polar solvent in the presence of an effective amount of a transition metal salt such that the tertiary alcohol is dehydrated.
摘要:
A method of making a substrate is described. The substrate has thereon or therein a colored composition which includes a mutable, colorant and a molecular includant. The colored composition is incorporated into or out of the substrate. The combination of ultraviolet radiation transorber and molecular includant is denominated a functionalized molecular includant.

The invention relates to stable aqueous solutions of voltage sensitive dyes. Particularly the invention relates to the proper formulation and storage conditions that provide marketable aqueous solutions of voltage sensitive dyes for use as optical imaging contrast agents.
摘要:
Applications of photoerasable colorant composition include photoerasable price markings for pricing goods, documents such as gaming tickets for securely communicating concealed information, photoerasable paint for temporary markings on terrain and structures such as signs, roadways, trees, and buildings, marking instruments such as pens, and wick or felt markers, ultraviolet light exposure indicators, and dry printing. The photoerasable or mutable colorant composition comprises a mutable colorant and an ultraviolet radiation transorber which, upon irradiation with ultraviolet radiation, interacts with the colorant to irreversibly mutate the colorant and thereby render the colorant substantially colorless. The mutable colorant composition may also include a molecular includant.

Die Farbstoffpräparate enthalten Wasser, einen in Wasser unlöslichen oder schwerlöslichen Farbstoff, ein Dispergiermittel sowie als Feuchthaltemittel eine Verbindung der Formel wobei R ein gegebenenfalls durch OH, CN, Halogen oder -N(Alkyl-C 1 -C 4 ) 2 - substituierter Alkylrest mit 1-16 C-Atomen und R' Wasserstoff oder die Gruppe -CH 2 -CHOH-CH 2 OH bedeutet. Die Präparate eignen sich für die Verwendung in wässrigen oder wässrigorganischen Färbeflotten oder Drucktinten oder auch zur Herstellung von Druckpasten. Sie sind auch nach teilweise oder völligem Eintrocknen sehr gut redispergierbar.
