Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
24 words
The method of claim 1 in which said fibers are formed from melted polymer and said dye receptors are incorporated into the melted polymer.
Claim 2
Dependent Claim
35 words
The method of claim 1 in which said polymeric disperse dye receptor is selected from the group consisting of poly(ethylene terephthalate), poly(1,3-di(4-piperidyl)propane adipamide), aklylated poly(vinyl pyrrolidone), and the self polymer of p( Beta -hydroxyethoxy)benzoic acid.
Claim 3
Dependent Claim
17 words
The method of claim 1 in which said organometallic metallizable disperse dye receptor is an organonickel compound.
Claim 4
Dependent Claim
13 words
The method of claim 4 in which said organonickel compound is nickel bis-(O-n-butyl-3,5-di-tert-butyl-4-hydroxybeNzylphosphonate).
Claim 5
Dependent Claim
40 words
The method of claim 1 in which said organometallic metallizable disperse dye receptor and said polymeric disperse dye receptor are incorporated into at least one of said fibers in unlike concentrations at various loci along the length of said fiber.
Claim 6
Dependent Claim
38 words
The method of claim 1 in which said polymeric disperse dye receptor is selected from the group consisting of poly(ethylene terephthalate), poly(1,3-di-(4-piperidyl)propane adipamide) and an alkylated poly(vinyl pyrrolidone) and said organometallic metallizable disperse dye receptor comprises nickel bis-(O-n-butyl-3,5-di-tert-butyl-4-hydroxybenzylphosphonate).
