Abstract: This invention relates to colored polyester thermoplastics comprised of polymeric colorants having poly(oxyalkylene) moieties and/or anionic dye/quatenary ammonium substantially inorganic salt-free colorant complexes mixed with diluents selected from the group consisting essentially of sorbitan (C.sub.8 -C.sub.22) monoesters, ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters, mixtures thereof of sorbitan (C.sub.8 -C.sub.22) monoesters and ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters, ethoxylated nonyl-phenol ethers, ethoxylated dodecylphenol ethers, mixtures thereof of said ethoxylated nonyl-phenol ethers and ethoxylated dodecylphenol ethers, and mixtures of (i) sorbitan (C.sub.8 -C.sub.22) monoesters or ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters and (ii) ethoxylated nonyl-phenol ethers or ethoxylated dodecylphenol ethers.

Abstract: A method for tagging one or a mixture of natural or synthetic materials comprising contacting the same with one or a mixture of tagging compounds containing one or more non-ionic luminophore moieties attached to at least one poly(oxyalkylene) moiety by means of a linking moiety; wherein said tagging compound has substantial absorbance within the range of from about 300 to about 400 nm and reemits substantial visible light, said contacting effecting at least a temporary association between said material and said compound wherein said compound is present in an amount between about 0.0001 and about 10 percent by weight of said material.

Abstract: A yarn pad, for use in conjunction with a circular-style floor cleaning machine, which resists folding or bundling and which is particularly adapted for use with dry-type carpet cleaning systems.
