The invention provides a water- and oil-repelling member having a primer layer as a first layer on at least one surface of a base material and further having a water- and oil-repelling layer as a second layer on the outer surface of the primer layer. The primer layer comprises a layer containing nano-diamonds and having a film thickness of 0.5 to 500 nm, the main component being an organic silicon compound having a plurality of silanol groups within a molecule. The water- and oil-repelling layer comprises a layer having a film thickness of 0.5 to 30 nm, the main component being a cured product of a hydrolysable fluorine-containing compound. The water- and oil-repelling member can stably and simply impart a water- and oil-repelling coat having excellent abrasion resistance to various base materials. In addition, the primer layer and the water- and oil-repelling layer can be coated even in a room-temperature (25 C.) process.

The present disclosure concerns a containment of pulp material that reduces reliance on adhesives and polymers. The containment is of two preformed semi-cylinders that linked together by using a preformed raised ridge that slots into a trough on the opposing half. The containment may optionally include a biopolymer based internal layer to provide a sealed containment. The present disclosure also concerns a cap for the containment with a narrowed wall and a recess to retain a lid liner with notched walls that allow for expansion at the closed end.

A coating solution for coating a metal sheet to be subjected to complicated forming is disclosed. The coating solution contains an acrylic resin having a glass transition point (Tg) of 100 C. or higher and an acid value-to-glass transition point ratio R=acid value (mg-KOH/g)/Tg ( C.) of 1.50 or more, and a polyolefin wax having a melting point of 100 C. or higher and 145 C. or lower and an average particle diameter of 3.0 m or less and is applied to a metal sheet.

Disclosed are quantum dot composite microspheres, quantum dot composite microsphere film and preparation method thereof. The quantum dot composite microsphere includes a core, a quantum dot layer adsorbed on a surface of the core, and an outer shell layer coated on the surface of the quantum dot layer, wherein one or more polymer ligands with an ionizable end group are attached to the surface of the outer shell layer. One or more polymer ligands with ionizable end groups are disposed on an outer shell layer of quantum dot composite microspheres. After the quantum dot composite microspheres are dissolved in a solvent, the quantum dot composite microspheres are charged positively or negatively, so that quantum dot composite microspheres are deposited on a positive electrode and a negative electrode during an electrodeposition process, thereby obtaining quantum dot composite microsphere film containing the such quantum dot composite microspheres.

The present invention also relates to an aqueous gel ink with variable color obtained according to the process of the invention, comprising said ester of retinol represented by formula (I) and silver nanoparticles. The invention finally concerns a writing instrument comprising an aqueous gel ink with variable color according to the invention.

A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique with high rate and resolution of metal part production due to a hybrid deposition/removal process.
