Abstract:
[Problem] To provide a method of effectively dyeing a thermoplastic resin plastic lens in arbitrary color tone and density and a colored plastic lens. [Means for Solution] A method of dyeing a resin plastic lens by dipping a thermoplastic resin plastic lens in a dyeing liquid containing a disperse dye and a monocyclic monoterpene, and a colored plastic lens obtained by dyeing by that method.
Abstract:
A reactive dye compound comprising (a) at least one chromophore moiety; (b) at least one SO2C2H4 group which is attached to the chromophore moiety either directly via the sulphur atom of the SO2C2H4 group or via a linking group L; characterised in that at least one SO2C2H4 group is substituted on its terminal carbon atom with at least one Y group wherein Y is derived from a hydrated aldehyde, a hydrated ketone, a hydrated alpha-hydroxy ketone or the hydrated form of formic acid, and linked via one of its oxygen atoms to the terminal carbon of the SO2C2H4 group thereby forming a hemiacetal. The compounds herein have high Exhaustion Values (E), high Fixation Values (F) and high Efficiency Values (T) and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, increasing the dye-substrate covalent bonding, increasing the ability to dye substrates at room temperature, decreasing the amount of dye that is removed during the post dyeing 'soaping off process' and therefore simplifying the post dyeing 'soaping off process' traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics. In addition, the compounds prepared above provide more intense dyeings and require less levels of salt for dyeing cotton substrates.

Abstract:
Disclosed are processes for tinting hydrogel materials, such as contact lenses, by dissolving a leuco sulfate ester of a vat dye in a compatible monomer solution, adding an oxidizing initiator to the monomer solution, and oxidizing and polymerizing the monomer solution and dye in the same solution. In one aspect, the oxidation and polymerization are conducted simultaneously whereas in another embodiment, the oxidation of the soluble leuco sulfate ester of a vat dye to the insoluble vat dye and polymerization are conducted sequentially in the same reaction medium.
Abstract:
A method of dyeing a polyamide fiber structure characterized by using a polyamide fiber structure which has structural differences along the fiber length direction and dyeing the structure with an anionic reactive dye in a dye bath having a pH of 3 to 8; and a dyed polyamide fiber structure obtained by the above method. The dyed structure is characterized by comprising a polyamide fiberstructure which has structural differences along the fiber length direction and has been dyed with a reactive dye and by having a color fastness in washing as stipulated by JIS L-0844 of grade 4 or higher. The dyeing method gives a dyed polyamide fiber structure having a high-quality, clear, grandrelle tone and excellent color fastness in washing.
Abstract:
The method for dyeing a polyamide fabric of the present invention comprises the step of dyeing a polyamide fabric having structural variations in the longitudinal direction of the fibers, by a dye liquor containing an anionic reactive dye and regulated at pH 3 ∼ 8. The dyed product of the present invention is a dyed polyamide fabric obtained by said dyeing method. Furthermore, the dyed product of the present invention is obtained as a grandrelle tone dyed product by dyeing a polyamide fabric having structural variations in the longitudinal direction of the fibers by a reactive dye, and being 4th or higher grade in the wash fastness specified in JIS L-0844. The present invention can provide a method for dyeing a polyamide fabric in a clear high grade grandrelle tone and to have excellent wash fastness, and also a grandrelle tone dyed product.
