Abstract: A method to improve the bleach resistance of a textile fiber is provided by having the steps of:(a) applying a solution or dispersion of a compound of the formula: ##STR1## where R.sup.1 and R.sup.2 are independently selected from the group consisting of H, CO.sub.2 R.sub.4, SO.sub.3 H, PO.sub.3 H, CON(R.sup.4).sub.2, OH, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, and halo, where R.sup.4 is H or C.sub.1 -C.sub.4 alkyl;R.sup.3 is selected from the group consisting of H, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkenyl, C.sub.1 -C.sub.4 alkylenephenyl, phenyl and COR.sup.5, where R.sup.5 is C.sub.1 -C.sub.4 alkyl, phenyl or benzyl, any of which may be substituted with up to two groups from R.sub.2 ; and salts of such compounds; in a solvent selected from the group consisting of water and C.sub.1 -C.sub.4 alcohol; and(b) drying said textile fiber to evaporate said solvent and deposit a non-volatile coating of said phenolic compound on a surface of said fiber.

Abstract: A diamino-xanthene colorant is provided having the following structure: ##STR1## where Y is a poly(oxyalkylene) substituent having a straight or branched polymer chain of at least 3 monomer units selected from ethylene oxide, propylene oxide, butylene oxide and glycidol;R.sub.1 and R.sub.2 are independently selected from H, C1-C4 alkyl, C1-C4 alkoxy, Cl, Br and I;X is selected from H, SO.sub.3 --, CO.sub.2 -- and COOR.sub.3, where R.sub.3 is C1-C4 alkyl or aryl; andeach Z is independently selected from SO.sub.3 --, CO.sub.2 --, COOR.sub.4, Cl and OH, where R.sub.4 is C1-C4 alkyl or aryl, and n is 0, 1, or 2; the colorant is synthesized by condensing two moles of an N,N-bis(poly(oxyalkylene))-p-methoxyaniline and o-formylbenzene sulfonic acid.

Abstract: A poly(oxyalkylene) substituted xanthene colorant is providing having the following structure: ##STR1## where Y is a poly(oxyalkylene) substituent having a straight or branched polymer chain of from 3 to 400 monomer units selected from ethylene oxide, propylene oxide, butylene oxide and glycidol;R.sub.1 and R.sub.2 are independently selected from H, C1-C8 alkyl, aryl and Y, provided that if either R.sub.1 or R.sub.2 are Y, the other is not H;R.sub.3 and R.sub.4 are independently selected from H, C1-C4 alkyl, C1-C4 alkoxy, Cl, Br and I;X is selected from H, SO.sub.3 --, CO.sub.2 -- and COOR.sub.5, where R.sub.5 is C1-C4 alkyl or aryl; andeach Z is independently selected from SO.sub.3 --, CO.sub.2 --, COOR.sub.6, Cl, and OH, where R.sub.6 is C1-C4 alkyl or aryl, and n is 0, 1, 2 or 3.The colorant is synthesized using a novel poly(oxyalkylene) substituted aminophenol intermediate.

Abstract: A method is provided for the preparation of a conductive composition containing a polymerized aromatic amine wherein the aromatic amine is oxidatively polymerized in an acidic aqueous medium in the presence of an oxidizing agent, a doping agent and an aromatic polyalkyleneoxide in an amount sufficient to stabilize the resulting composition. Preferably, the aromatic amine is aniline or a substituted aniline. Compositions produced by such method are also disclosed. These compositions are useful for treating various substrates to make such substrates conductive.

Abstract: A process for heat treating substituted and/or unsubstituted polyaniline which has been doped with a relatively non-volatile acid is provided. Subjecting polyaniline to temperatures of between 70.degree. C. and 200.degree. C. for a moderate amount of time dramatically lowers the resistance, and therefore increase the conductivity, of the polyaniline. Heat treatment of polyaniline may be advantageously combined with a subsequent rinsing step to produce a sample which has superior stability and good conductivity.

Abstract: Azo chromophores having polyoxyalkylene substituents are linked together by a covalent bond or by an intervening connecting group to form dimers or trimers. The polyoxyalkylene substituents are straight or branched chain polymers primarily of ethylene oxide which make the dimer and trimer colorants useful as fugitive tints.
