Abstract: Thermal ink-jet inks are provided containing a colorant and a vehicle, the vehicle comprising from about 8 to about 20 wt % of a 1,2-diol, from about 0.1 to about 5 wt % of at least one non-ionic surfactant, and optionally 0 to about 5 wt. % of a aliphatic alcohol; 0 to about 1.5 wt % of at least one component independently selected from the group consisting of buffers, biocides, and metal chelators; and the balance water. The inks formulated according to the present invention provide the desired dot gain and dot symmetry on the print medium, in particular, gelatin coated media, while providing excellent color-to-color bleed alleviation. The images generated with the inks of the present invention exhibit excellent, near photographic image quality.

Abstract: An oxygen scavenging packages and containers which comprise a composition of a carrier, such as a polymer, which is permeable to both oxygen and water or water vapor and an oxygen scavenging compound of an organic compound or salt thereof dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger. The oxygen scavenging compound is a salicylic acid chelate or complex of a transition metal or a salt thereof. The oxygen scavenging composition is activated for scavenging oxygen by contact with water or water vapor which permeates into or through the carrier. A reducing agent of an ascorbate compound may be added to enhance the performance of the salicylic acid chelate or complex. The oxygen scavenging compound may be added to the composition in a dry state, and is inactive until activated for oxygen scavenging by contact with water or water vapor.

Abstract: An oxygen scavenging composition of a polymer which is permeable to both oxygen and water or water vapor, and an oxygen scavenging material of an amino polycarboxylic acid chelate or complex of a transition metal, or salt thereof, dispersed relatively uniformly throughout the polymer in an amount effective to act as an oxygen scavenger when activated for scavenging oxygen by contact with water or water vapor which permeates the polymer. A preferred oxygen scavenging compound is ferrous EDTA or salts thereof. Also, an ascorbate compound may be used as a preservative or augmenter for the oxygen scavenging compound.

Abstract: Methods and apparatus for the extraction of a ligand such as molecular oxygen from a first fluid environment and for release of a ligand such as molecular oxygen, as well as ligand carrier compounds therefor comprising linear, pentadentate polyalkylamines and transition metal ions. The carrier compounds have the general formula: ##STR1## where, each of R.sub.1 and R.sub.2 is independently an organic group including a sulfur, an oxygen or a nitrogen coordinated to M;each of m, n, o, and p is 1, 2, 3, or 4;X is selected from the group consisting of 2,6-pyridyl, 2,6-piperidyl, 2,5-pyrrolyl, 2,4-imidazolyl, substituted heterocyclic amines, --)--, --S--, ##STR2## and ##STR3## where R.sub.3 is hydrogen, lower alkyl or aralkyl; and M is a transition metal ion.
