Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
75 words
A carrier for a dye for polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
Claim 2
Dependent Claim
75 words
A carrier for a dye for polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
Claim 3
Dependent Claim
14 words
The carrier of claim 1 including a compatible dispersing agent for said swelling agent.
Claim 4
Dependent Claim
27 words
The carrier of claim 2 wherein said dispersing agent consists of at least one anionic surfactant, at least one non-ionic surfactant and at least one coupling solvent.
Claim 5
Dependent Claim
40 words
The carrier of claim 3 wherein about 10% by weight of the total carrier is anionic surfactant, about 5% by weight of the total carrier is non-ionic surfactant and about 5% by weight of the total carrier is coupling solvent.
Claim 6
Dependent Claim
29 words
The carrier of claim 2 wherein said swelling agent comprises about 80% by weight of the carrier and the dispersing agent comprises about 20% by weight of the carrier.
Claim 7
Dependent Claim
84 words
A dyeing composition for polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid a dye, a carrier for said dye and water, said carrier comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
Claim 8
Dependent Claim
84 words
A dyeing composition for polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid a dye, a carrier for said dye and water, said carrier comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
Claim 9
Dependent Claim
17 words
The composition of claim 6 wherein said carrier includes a compatible dispersing agent for said swelling agent.
Claim 10
Dependent Claim
27 words
The composition of claim 7 wherein said dispersing agent consists of at least one anionic surfactant, at least one non-ionic surfactant and at least one coupling solvent.
Claim 11
Dependent Claim
40 words
The composition of claim 8 wherein about 10% by weight of the total carrier is anionic surfactant, about 5% by weight of the total carrier is non-ionic surfactant and about 5% by weight of the total carrier is coupling solvent.
Claim 12
Dependent Claim
29 words
The composition of claim 6 wherein said swelling agent comprises about 80% by weight of the carrier and the dispersing agent comprises about 20% by weight of the carrier.
Claim 13
Independent Claim
94 words
A method of dyeing polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid which comprises applying to said fibers a dyeing composition comprising a dye, a carrier for said dye and water, said carrier comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
Claim 14
Independent Claim
94 words
A method of dyeing polyamide fibers made by the condensation of the monomers 4,4'-diamino-dicyclohexyl methane, or alkylated derivatives thereof, and dodecanoic acid which comprises applying to said fibers a dyeing composition comprising a dye, a carrier for said dye and water, said carrier comprising a swelling agent consisting of a mixture of normal-butyl benzoate and an alkyl phenol selected from the group consisting of para-tertiary butyl phenol and para-tertiary amyl phenol, said butyl benzoate and alkyl phenol being present in a ratio to each other of between about 1:2 to about 2:1 by weight.
