An aqueous ink jet ink is made by forming a mixture of a pigment, an optional dispersant if the pigment is not self-dispersing, dispersing, and a urethane polymer or prepolymer dispersion in water. This ink is useful in a variety of ink jet printing applications such as printing on wide format substrates and textiles.

Aqueous ink jet ink composition

This invention relates to aqueous polyurethane compositions suitable for dipped surgeon's gloves and related articles needing toughness, pliability, and some solvent resistance. The gloves replace natural latex gloves which can cause allergic reactions and/or isoprene gloves which have their own drawbacks.

Polymers for surgeons gloves

A breathable polyurethane having an upright moisture vapor transmission rate (MVTR) of more than about 500 gms/m/24 hr comprises: Coatings and films for textiles and other articles and applications using such polyurethanes have excellent breathability, i.e., high moisture vapor transmission rates (MVTR).

Breathable polyurethanes, blends, and articles

Waterborne polyurethane dispersions are prepared by reacting (1) at least one polyisocyanate; (2) at least one active hydrogen containing compound, such as a polyol or a polyamide; and (3) preferably also at least one water-dispersability enhancing compound having water-dispersion enhancing groups, in order to form an isocyanate terminated prepolymer. The prepolymer subsequently is (1) optionally neutralized by reaction with at least one neutralizing agent, (2) dispersed in water, and then (3) chain extended by reaction with at least one of water, inorganic or organic polyamine having an average of about 2 or more primary and/or secondary amine groups, or combinations thereof. At least one plasticizer is introduced into the reaction mixture at any time during prepolymer formation or before the prepolymer is dispersed in water. The plasitcizer substantially or completely replaces other organic diluents or solvents. Various types of plasticizers may be employed, including reactive plasticizers.

Plasticized waterborne polyurethane dispersions and manufacturing process

A waterborne dispersion of a polyurethane polymer is disclosed, which is useful as a film having improved mechanical properties. More particularly, the film has properties comparable to rubber; including, a percentage elongation greater than 700%; a tensile strength greater than 3500 psi; a 100% modulus below 450 psi; a 300% modulus below 700 psi; and, a 500% modulus below 1500 psi. The film can be prepared in the absence of a solvent, thus making it attractive for a variety of protection products for medical and industrial applications such as gloves, condoms, catheters, and the like. The polymer is useful as a coating for textiles, such as backcoatings, fabric or fiber saturants, finishes, or transfer coatings, or other textile and non-textile applications where good elastomeric properties would be useful.
