A water soluble polymer composition comprising a water soluble polymer (e.g., polyvinyl alcohol-co-vinylpyrrolidinone (PVOH-co-PVP)) and a sugar (e.g., trehalose).

A reactive digital printing method can be performed with the following steps: 1) applying a primer to a fabric to be printed; (2) applying an ink containing a dye with multi-reactive groups to the fabric to be printed in step (1); (3) steaming and coloring, washing, dehydrating and shaping the fabric in step (2), to obtain a printed product. A related system with a combination of primer, a dye with multi-reactive group, printed fabric produced with the reactive digital printing method and items comprising the printed fabric can also be provided.

The present invention relates to biomaterial in the form of dispersion of cellulose nanofibrils with extraordinary shear thinning properties which can be converted into desire 3D shape using 3D Bioprinting technology. In this invention cellulose nanofibril dispersion, is processed through different mechanical, enzymatic and chemical steps to yield dispersion with desired morphological and rheological properties to be used as bioink in 3D Bioprinter. The processes are followed by purification, adjusting of osmolarity of the material and sterilization to yield biomaterial which has cytocompatibility and can be combined with living cells. Cellulose nanofibrils can be produced by microbial process but can also be isolated from plant secondary or primary cell wall, animals such as tunicates, algae and fungi. The present invention describes applications of this novel cellulose nanofibrillar bioink for 3D Bioprinting of tissue and organs with desired architecture.

Aqueous composition comprising: from 0.5% by weight to 5% by weight, preferably from 1% by weight to 4% by weight, with respect to the total weight of said aqueous composition, of at least one conductive polymer; from 1% by weight to 100% by weight, preferably from 2% by weight to 10% by weight, more preferably from 15% by weight to 50% by weight, with respect to the total weight of said at least one conductive polymer, of at least one cellulose ether.

Said aqueous composition may advantageously be used as a printable ink or printable paste in various techniques such as, for example, screen printing, gravure printing, flexographic printing, spray coating, slot die coating, spin-coating, ink-jet printing. Preferably, said aqueous composition may advantageously be used as a printable paste for screen printing. More particularly, said aqueous composition may be used for the preparation of electrically organic conductive layers, even more particularly for the preparation of electrically organic conductive layers used in photovoltaic cells (or solar cells), in printable electronics, in organic light-emitting diodes (OLEDs), in touch screens, in antistatic coatings.

Described herein is a printing ink or coating composition that includes: (a) one or more elastomeric polyurethane resins with amine functionality having a glass transition temperature of about −45° C. to about −70° C.; (b) one or more acrylic resins based on a methacrylate/styrene co-polymer with a glass transition temperature of about 45° C. to about 110° C.; (c) one or more nitrocellulose binders; (d) one or more solvents; and (e) optionally, one or more waxes and/or one or more colorants. The inks and coating compositions are well suited for printing onto shrink sleeve label substrates, such as by flexographic and gravure printing. The inks and coatings provide exceptional printability and resistance to chemicals, to softening, to re-wetting, and to set-off.
