Abstract:
This disclosure is directed to a black effect pigment and a method of forming said pigment. The pigment comprises a platy substrate coated with SnO2 and/or SnO2 hydrates and Fe3O4 with an optional coating of metal oxides such as SiO2, TiO2, ZrO2 and ZnO2. The deposition of the SnO2 and/or SnO2 hydrates onto the substrate improves the adhesion and prepares the substrate surface for deposition of the iron oxides onto the platy surface, especially mica surfaces. While the pigment may be used in such applications as coating, powder coating, printing ink, plastic, ceramic material, glass, cosmetic formulation, laser marking pigment, pigment composition or dry preparation, the pigment is especially suitable for cosmetic applications.
Abstract:
A CVD process for depositing a silica coating is provided. The process includes providing a glass substrate. The process also includes forming a gaseous mixture including a silane compound, oxygen, a fluorine - containing compound, and a radical scavenger such as ethylene or propylene. The gaseous mixture is directed toward and along the glass substrate and is reacted over the glass substrate to form the silica coating thereon.
Abstract:
The invention is drawn to a transparent diffusive OLED substrate comprising the following successive elements or layers: (a) a transparent flat substrate (1) made of mineral glass having a refractive index n 1 of between 1.48 and 1.58, (b) a monolayer of mineral particles (3) attached to one side of the substrate (1) by means of a low index mineral binder (2) having a refractive index n 2 of between 1.45 and 1.61, and (c) a high index layer (4) made of an enamel having a refractive index n 4 comprised between 1.82 and 2.10 covering the monolayer of mineral particles (3),
the mineral particles (3) having a refractive index n 3 comprised between n 2 +0.08 and n 4 -0.08 and protruding from the low index mineral binder (2) so as to be directly in contact with the high index layer (4), thereby forming a first diffusive interface (Di 1 ) between the mineral particles (3) and the low index binder (2), and a second diffusive interface (Di 2 ) between the mineral particles (3) and the high index layer (4).
