Abstract
Abstract The present invention provides a method of dyeing with aqueous dispersed dyes which comprises using as dye carrier a composition comprising 30 to 60 parts by weight of diphenyl, 5 to 35 parts by weight of a phenyl toluene and 5 to 25 parts by weight of fluorene, provided the total of said parts by weight does not exceed 100. The invention also provides a dye carrier composition as specified above and comprising also an emulsifier. The invention is particularly useful in the dyeing of polyester fibres.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
54 words
The method of claim 1, wherein the carrier contains an emulsifier comprising from 80 to 95 weight % of an anionic dispeRsing agent and 5 to 15 weight % of a non-ionic dispersing agent, provided that the emulsifier comprises no more than 5% dispersing agents having more than 30 ethylene oxide units per molecule.
Claim 2
Dependent Claim
16 words
The method of claim 2 wherein the emulsifier contains a foam inhibiting amount of paraffin oil.
Claim 3
Dependent Claim
67 words
The method according to claim 2 wherein the emulsifier is a member of the group consisting of ethylene oxide-alkyl phenol and ethylene oxide-castor oil adducts; alkyl benzene sulphonates; dodecyl diphenyl ether disulphonate; sulphonated condensates of phenol or naphthalene with formaldehyde; sulphonates of castor oil, oleic ester, alkyl naphthalene, succinic diethyl hexyl ester, xylene or toluene; fatty acid ethers; and ethers of aryl phenyl and alkyl phenyl polyglycols.
Claim 4
Dependent Claim
12 words
The method according to claim 2 wherein the material dyed is polyester.
Claim 5
Dependent Claim
94 words
A composition comprising water, a dye dispersed in said water, and as carrier for said dye a mixture comprising 30 to 60 parts by weight of diphenyl, 5 to 35 parts by weight of a phenyl toluene and 5 to 25 parts by weight of fluorene, provided the total of said parts by weight does not exceed 100 and an emulsifier in an amount from 5 to 30 % by weight of the carrier, provided that the emulsifier comprises no more than 5% dispersing agents having more than 30 ethylene oxide units per molecule.
Claim 6
Dependent Claim
67 words
The composition according to claim 6 wherein the emulsifier is a member of the group consisting of ethylene oxide-alkyl phenol and ethylene oxide-castor oil adducts; alkyl benzene sulphonates; dodecyl diphenyl ether disulphonate; sulphonated condensates of phenol or naphthalene with formaldehyde; sulphonates of castor oil, oleic ester, alkyl naphthalene, succinic diethyl hexyl ester, xylene or toluene; fatty acid ethers; and ethers of aryl phenyl and alkyl phenyl polyglycols.
Claim 7
Dependent Claim
42 words
The composition of claim 6, wherein the carrier comprises also from 1 to 30 parts by weight of other aromatic substances selected from the group consisting of naphthalene, diphenyl ether, diphenyl methane, benzoic methyl ester, benzoic ethyl ester, tetrahydronaphthalene and mixtures thereof.
Claim 8
Dependent Claim
32 words
The composition of claim 8, in which the emulsifier comprises from 80 to 95 weight % of an anionic dispersing agent and 5 to 15 weight % of a non-ionic dispersing agent.
Claim 9
Dependent Claim
15 words
The composition of claim 9, comprising also paraffin oil as emulsion stabilizer and foam inhibitor.
Claim 10
Dependent Claim
61 words
The composition of claim 10, wherein the dye carrier comprises 80 weight % of a carrier mixture itself comprising about 30 weight % diphenyl, 25 weight % phenyl toluenes, about 15 weight % fluorene and about 25 weight % of other aromatic substances; about 5 weight % paraffin oil; and about 15 weight % of monoethanolamine salt of dodecyl benzenesulphonic acid.
