Definitions

  • the film-forming solution contains particles of selectively absorbing ultrafine pigment or combination of pigments with a diameter of less than 80 nm, having at least two transmittance maxima in the visible range.
  • the film-forming solution may further contain an additive that promotes an increase in adhesion and a stabilizing additive.
  • a method of obtaining a substrate of a multilayer pigment includes the following steps: feeding a film-forming solution to the foaming device to form a foam material; convective, radiation or inductive drying of the foam material; grinding dried foam to form substrate particles; washing the obtained particles with acid and water; drying and heat treatment of particles.
  • a foaming device a frame blown by an air stream or a venturi can be used.
  • a pigment with metameric properties or a metameric combination of pigments for coloring a substrate eliminates the Fresnel reflection of light, which gives transparent pearlescent pigments an achromatic white hue, and, at the same time, enhances two or more colors reflected by a multilayer pigment.
  • the use of a multilayer metameric dielectric coating allows one to enhance the metameric properties of conventional metameric pigments or to achieve a metameric effect in the spectral range where conventional pigments are not effective.
  • Example 4 Obtaining a colored substrate.

Abstract

La présente invention concerne des pigments multicouches nacrés offrant une transition de couleur contrastée lors du changement de l'angle d'observation ou lors du changement des conditions d'éclairage, lesquels sont obtenus à partir d'un substrat transparent colorés par un pigment métamères ou une combinaison métamère de pigments, ceci en y appliquant au moins une couche diélectrique ayant un effet d'interférence qui donne une teinte différente selon différents angles d'observation, ou au moins deux couches diélectriques ayant un effet d'interférence qui réfléchissent au moins deux sections différentes du spectre visible sous un même angle d'observation. Le substrat transparent teinté est obtenu à partir d'une solution colloïde tensioactive d'une substance liante contenant des pigments métamères à ultradispersion avec un diamètre des particules inférieur à 80 nm. Le substrat obtenu permet de réduire la diffusion Fresnel de la lumière et de renforcer le contraste de changement de couleur réfractée par par les couches diélectriques lors du changement d'angle d'observation ou du changement des conditions d'éclairage.
