The disclosure relates to ink compositions for digital printing on an external surface of a plastic article. The ink compositions comprise an ink removal-promoting additive. In some aspects, the ink removal-promoting additive can facilitate the separation or loosening of the image from the external surface of the article when the image is exposed to a liquid-based solution at an elevated temperature. Also disclosed are recyclable plastic articles having an external surface with an image printed thereon using the disclosed ink composition and methods for removing cured ink from a plastic container. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

An eraser for removing strokes of writing, painting and/or drawing implements, including at least one binder and at least one plasticizer, wherein the at least one plasticizer is a polyol ester.

The present invention provides a release agent for a reactive hot melt resin, wherein a dispersion term (D) in the Hansen solubility parameters falls within the range of 14.0 to 21.0 MPa.sup.0.5, a dipole interaction force term (P) falls within the range of 0 to 10.5 MPa.sup.0.5, and a hydrogen bond term (H) falls within the range of 0 to 13.5 MPa.sup.0.5. Preferably, the adhesive for a reactive hot melt resin is at least one type of solvent selected from a group consisting of benzoic acid esters, tetrahydrofurfuryl alcohol, and tetrahydrofurfuryl (meth)acrylate. The reactive hot melt resin preferably contains an urethane prepolymer having an isocyanate group, and the urethane bond content in the urethane prepolymer is preferably within the range of 0.1 to 3 mol/kg.

Semiconductor-Oxides Nanotubes-Based Composite Particles Useful for Dye-Removal and Process Thereof, has been described in this invention, which relates to an innovative method, involving an ion-exchange mechanism operating under the dark-condition in an aqueous solution, for the processing of innovative products consisting of the nanotubes of semiconductor-oxides deposited on (or anchored to or attached to) the surface of flyash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles find potential application in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via the surface-adsorption process, involving the ion-exchange and electrostatic-attraction mechanisms, operating in the dark-condition. The novel composite particles can be recycled for the next-cycle of dye-adsorption by decomposing the previously adsorbed-dye on their surfaces via an innovative approach involving the use of either noble-metal-deposited photocatalyst or a magnetically separable magnetic photocatalyst and an exposure to the ultraviolet (UV) or solar-radiation.
