Abstract: A method is disclosed for producing flakes of a first material, the method comprising: a) supporting two supply cylinders of the first material and a fatiguing rod assembly, that includes at least one textured fatiguing rod, so that each fatiguing rod is sandwiched between the two cylinders, each fatiguing rod having a diameter smaller than an initial diameter of the two supply cylinders and being made of a second harder material; b) urging the surfaces of the two supply cylinders into contact with each fatiguing rod; and c) causing the supply cylinders and the fatiguing rod(s) to rotate while making rolling line contact with one another; wherein the supply cylinders and each fatiguing rod are urged against one another with sufficiently high contact pressure to modify the surface of the supply cylinders by fatigue and result in separation of flakes from the surfaces of the cylinders.

Abstract: The present disclosure relates to a method for styling mammalian hair fibers, including providing body, straightening, relaxing, curling, or applying any other desired modification to the shape of the hair. The method comprises applying a hair styling composition comprising at least one hair-penetrating phenol-based monomer to the hair, allowing the monomers to penetrate within the hair and curing such monomers to internally form a polymer able to overcome the tendency of the hair to revert to its native shape. When curing is performed while the hair is in a desired modified shape, the resulting polymers may maintain the modified shape. Suitable compositions and kits allowing to prepare the same are also disclosed.

Abstract: There is disclosed a method of coating mammalian hair, the method comprising applying, on the external surface of individual hairs of the mammalian hair, an oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) an oil phase containing at least one water-insoluble reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing, forms an elastomer. The reactive oil phase may further contain a plurality of sub-micronic pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as methods for preparing the compositions.

Abstract: There is disclosed a print construction comprising: (a) a printing substrate having an image-receiving surface; (b) a receptive layer, at least partially covering said image-receiving surface, and having a particle reception surface distally disposed to said image-receiving surface, said receptive layer optionally having a thickness of at least 1000 nanometer (nm); and (c) a plurality of individual particles adhered to said particle reception surface, and forming a monolayer thereon, the features of which are described herein.

Abstract: A process for metallising a polymeric surface of an article, the process including applying to the polymeric surface a liquid carrier containing a suspension of metallic or metal-looking particles, wherein the polymeric surface and the liquid carrier are such that the wetting angle between the liquid carrier and the polymeric surface is of substantially 90° or above, and wherein the particles and the polymeric surface are such that the particles have a greater affinity to the polymeric surface than to one another or to the liquid, whereby particles suspended in the liquid migrate to the interface between the liquid and the polymeric surface to form a monolayer coating of particles on the polymeric surface.
