Disclosed is an inkjet ink that is jettable through standard inkjet nozzles, yet creates a non-abrasive non-porous three-dimensional glass structure on a 1-100 micron-scale without the need for additional processes beyond those normally used for the inkjet decoration of glass substrates. Such an inkjet ink can avoid the drawbacks noted above and is described herein.

There is disclosed a catalytic substrate surface where in the substrate surface comprises particles in the size range 2-500 nm, said particles comprising TiO, wherein at least 50 wt % of the Ti in the particles is leachable in 37% HCl. A method for its manufacture is also provided. One advantage is that the higher fractions of Ti leachable in 37% HCl give a better coating with better adhesion, in particular on objects comprising protonatable acidic oxides, such as SiO. The higher fraction of Ti leachable in 37% HCl gives better transparency and dispersion stability. The resulting surface exhibits both improved activity and improved adhesion of the particles. There is no color change and/or speckles on the substrate, allowing anti-pollution surfaces to be produced also on decorative surfaces. The TiO-comprising layer is thin and easily applied in the production line.

Catalytic substrate surface

The present invention provides a bead comprising: i) an external zone comprising a super absorbent polymer (SAP) that is capable of absorbing at least about 5 times its weight in water, surrounding ii) at least one internal zone comprising a core that contains at least one agrochemical, wherein the external zone is permeable to oxygen when hydrated, or the internal zone is formulated to release the at least one agrochemical into the external zone over a period of at least about one week when the hydrogel of the external zone is hydrated. The present invention also provides methods of using beads of the invention.

Microenvironment for efficient uptake of fertilizers and other agrochemicals in soil

Liquid compositions for etching glass are disclosed herein. The liquid composition may include a non-active etching agent precursor that is inactive with respect to chemically etching glass in an amount of at least 2.5% by weight of the total composition, a binder and a liquid vehicle. The precursor may include an alkali metal salt having an activation temperature of at least 400&#xb0; C. and when heated to above the activation temperature, the precursor yields an active etching agent suitable for chemical etching of glass.

Etching compositions, methods and printing components

A liquid etching composition comprising: (a) at least one etching agent precursor having an activation temperature of at least 400&#xb0; C., at which temperature said precursor yields an active agent suitable for chemical etching of glass, said precursor present at a concentration of at least 2.5% w/w; (b) a binder; and (c) a liquid vehicle.

Disclosed are a new composite material and a process for synthesizing highly charged, highly monodisperse, core-shell particles with high refractive index cores, as well as stable, long lasting crystalline colloidal arrays (CCAs) formed thereof. A preferred embodiment of the core particle can be highly monodisperse zinc sulfide (ZnS) particles and a preferred embodiment of the shell can be highly charged polyelectrolytes. The CCAs formed thereof are charge stabilized photonic crystals that shows distinctive first and second order Bragg diffraction peaks whose locations vary over a wide spectral region from UV through visible to IR, with unusually strong intensity and broad band width due to the high index of refraction. These high refractive index particles are useful in applications such as optical filters, optical coatings, cosmetics and photonic crystals sensors and devices.

High refractive index crystalline colloidal arrays materials and a process for making the same

One aspect of the present disclosure is directed towards a new film forming paint that Bragg diffracts light in the visible and NIR spectral regions. The paint may be comprised of highly charged polymer spheres that self assemble and maintain their diffraction in the presence of the different ingredients of the paint formulation, so that the self assembled arrays diffract light in both wet and dry states. Another aspect of the present invention is directed to a process for making highly charged polymeric spheres. Another aspect of the present invention is directed to the highly charged polymeric spheres themselves. The high surface charge density of the spheres enables the stability and self assembly of the spheres in the presence of the other paint ingredients. These spheres can find useful practical applications in paints, inks, coatings, cosmetics and light filtering applications. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

An Ink-jet ink composition for piezoelectric in-jet printing comprising: (a) a hydrophobic dye; (b) an oil-in-water microemulsion including: (i) a volatile oil; (ii) water; (iii) a co-solvent; (iv) at least one surfactant; and (v) a binder, wherein upon application of the ink to a substrate surface, the volatile oil evaporates and nanoparticles are formed. The invention additionally discloses a printing process using the ink composition.
