The invention relates to a method for coating textiles and/or leather, comprising applying at least one polyurethane urea dissolved in a solvent or solvent mixture, wherein the solvent consists of one or more monohydroxy-functional alcohols, or a solvent mixture consisting of organic solvents, containing >80 wt. % of at least one monohydroxy-functional alcohol in relation to the total mass of the solvent mixture is used, and wherein the polyurethane urea is formed by: a) at least one araliphatic, aliphatic and/or cycloaliphatic diisocyanate; b) at least one polyether polyol having a number average molecular weight M.sub.n400 and 6000 g/mol and an average hydroxyl functionality of 1.5 and 4; c) at least one amino-functional compound having at least two isocyanate reactive amino groups; and optionally other components. The invention also relates to a textile or leather coating produced using this method and a dissolved polyurethane urea, and to the use of the polyurethane urea for coating substrates and for producing free films.

An object of the invention is to provide a heat-resistant hexavalent chromium removal agent, which is capable of remaining in a leather or leather article for a long period of time and stably detoxifying hexavalent chromium over the long term even when a leather or leather article contains hexavalent chromium, and a leather or leather article, in which the hexavalent chromium content is less than 3 ppm. The leather or leather article of the present invention contains at least: an organic compound (A) having a structure shown in chemical formula (1) and hydroxyphenyl but not aldehyde and carboxyl, which organic compound has a property to reduce hexavalent chromium to trivalent chromium; and trivalent chromium, and the hexavalent chromium content determined in accordance with ISO 17075: 2008-02 is less than 3 ppm.

Provided is an ink jet liquid composition including an organic solvent, a bifunctional urethane (meth)acrylate oligomer having a weight-average molecular weight of 2,000 to 15,000, a photopolymerization initiator, and a vinyl chloride-vinyl acetate copolymer, in which a content of the organic solvent is 40% by mass or more and 90% by mass or less with respect to a total mass of the liquid composition. Also provided is an ink jet recording method using the ink jet liquid composition.

A needle-point pen apparatus and methods for administering a medication. The needle-point pen apparatus can include a barrel, a needle movably disposed within an inner channel of the barrel, the needle having a tip and an elongate shaft. A driving unit is coupled to the needle and provides a driving actuation to the needle. The driving actuation causes the needle to reciprocate within the barrel between one or more extended and retracted positions. The needle being designed to at least partially insert the medication into living tissue. A medication reservoir supplies the medication to the needle for at least partial insertion into the tissue. A computing device controls the needle actuation and the supply of the medication to the needle for controlling administration of the medication at multiple different computer-controlled depths and/or locations of the tissue.

Needle-point pen apparatuses and methods for marking and/or creating articles and objects. Other uses for the needle-point pen are also disclosed herein. Further needle, ink, and carriage control improvements are further discussed as well as marking and manufacturing processes. Further control, characterization and design parameters, components, and processes are disclosed. Methods for designing and manufacturing articles as well as collaboration between artists and article designers, including distributed and remote collaboration, are disclosed. New marking techniques, computer control, software, hardware and interactive techniques are further disclosed. And, designs and use of the needle-point pens are further described and illustrated.
