摘要:
A dye discharge composition exhibiting extended shelf life and/or pot life and high suitability for inkjet printing on dyed substrates, is disclosed. The composition comprises a reducing agent such as, for example, a sulfur-based reducing agent, and a chelating agent, such as a sodium salt of a polyamino carboxylic acid chelating agent. Use of the dye discharge composition in combination with a translucent colored composition and an optional opaque underbase composition, for forming an image on a dyed substrate is also disclosed. Processes for inkjet printing of an image on a dyed surface using the dye discharge composition, kits for use in such processes or an ink formulation containing same are also disclosed.

New phosphorus compounds are provided which correspond to the formula ##EQU1## wherein R.sub.1 and R.sub.2 each denote alkyl with 1 to 6 carbon atoms, X denotes alkylene with 1 to 4 carbon atoms and A denotes phenyl substituted by hydroxyl, alkoxy with 1 to 4 carbon atoms, alkoxy carbonyl with 2 to 5 carbon atoms, phenyl or halogen and n is 1 or 2. These compounds are useful as flameproofing agents for organic fiber material, especially for polyamide, polyacrylonitrile or linear polyester fibers, when applied according to the dry thermal transfer process.
摘要:
A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with the fiber materials especially polyamide, polyacrylonitrile or linear polyester fibers, thereafter the carrier and the material to be finished are subjected to a heat treatment at not less than 80.degree. C and the finished material is then separated from the carrier.The preparation which is applied in this process contains a halogen compound of the formulaR.sub.0 -- X -- A.sub.0wherein R.sub.0 is halogenoalkyl, X is --CO--NY--, --COO--, --OCO-- or --O--, Y is hydrogen or hydroxyalkyl, A.sub.0 is halogenoalkyl, --NH.sub.2, alkylene--COOH or --alkylene--O-halogenoalkyl, and wherein, if X is --CO--NY-- and Y is hydrogen, A.sub.0 can also be hydrogen, and if X is --O--, R.sub.0 and A.sub.0 can also be halogenoalkyl or halogenoalkenyl.
摘要:
Artificial, shaped articles of polymeric material having improved dyeability are provided by the incorporation therein of sulfones containing alpha-methylene groups. The dye receptability of artificially prepared fibers, yarns, fabrics and other shaped articles in often in need of improvement, so that these materials can be deep dyed in various types of dyeing procedures. While methods for improving the dyeability of various artificial fibers, including, for example, rayons, acetates, triacetates, acrylics, modacrylics, vinyons, sarans and the like are known, such methods generally vary from one type of fiber to another.

A process for flameproofing organic fiber material by the dry thermal transfer process is provided. In this process, a preparation is applied to an inert carrier which is then brought into contact with fiber materials, such as polyamide, polyacrylonitrile or linear polyester fibers; thereafter the carrier and the material are subjected to a heat treatment at not less than 80.degree.C and the finished material is then separated from the carrier. The preparation used in this process contains a halogen compound of the formula ##SPC1##Wherein A is halogen, hydroxyl, alkoxycarbonyl, halogenoalkoxy or halogenophenyl and X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 are each halogen, alkyl, hydroxl or hydrogen, but at most one of the radicals X.sub.1, X.sub.2, X.sub.3, X.sub.4 and X.sub.5 is alkyl or hydroxyl and at least one of the radicals is halogen, and X.sub.1 and A can together be a radical of the formula --CO--O--CO.
