Abstract
The invention relates to a novel pearlescent pigment having high color depth and brightness. The novel pearlescent pigment is made of substances which are prepared by coating transparent or translucent inorganic flaky materials (including natural mica, synthetic mica, glass sheet, silicon oxide, aluminum oxide, iron oxide and bismuth oxychloride crystals) with Prussian blue (Fe4[Fe(CN)6]3) and coating these flaky materials with metal or metal oxide, wherein the particle diameter of the inorganic flaky materials is 5-1000 micrometers, and the thickness is 0.1-5 micrometers; and the thickness of the coated Prussian blue film is 1-100 nanometers. The pearlescent pigment prepared from Prussian blue is widely used in the industries of paint, cosmetics, ink, plastics, leather and the like.
Description
Technical field
The present invention relates to a kind of Prussian blue serial pearl effect pigment, particularly by Prussian blue (Fe
4[Fe (CN)
6]
3) the transparent or semitransparent inorganic flaky material that coats.
Background technology
A fritz who is named as the Di Si Bach is arranged, with xanchromatic crystal yellow prussiate of potash K 18th century
4Fe (CN)
6Add in the solution of iron trichloride, just produced the very bright-coloured blueness deposition of a kind of color, first has invented Prussian blue.Hereafter Prussian blue as the application widely of pigment quilt.
Since eighties of last century sixties, E.I.Du Pont Company has invented since the pearly pigment, and pearly pigment is widely used in coating, makeup, plastics, fields such as leather and printing ink.The pearly pigment of all these preparations all is at natural mica, synthetic mica, sheet glass; Silicon-dioxide, aluminum oxide, the surperficial coated titanium of inorganic transparent such as red stone and bismuth oxychloride crystals or translucent flaky material, iron; MOXs such as tin, light forms the acting in conjunction that reflects and reflect through the surface of these films, and is last because the difference of film thickness forms Huang; Red, purple, indigo plant, color such as green.Through the pearly pigment that above-mentioned principle forms, its blue effect is the diffraction colour that is formed by light through optical principle, so the depth of shade of this type of pearly pigment is lower.
In order to overcome the shortcoming of above-mentioned pearly pigment; Can produce pearly pigment with higher blue depth of shade; Patent (German Patent No.1192353 and USP 2995459) has proposed with the mode of organic mill base through electroless plating, and having prepared with inorganic flaky material is having than the high color density pearly pigment of base material.But this kind mode is not suitable for preparing the pearly pigment of high brightness, because the pearly pigment that coats with this coloring mode, the chemical substance particle that is coated on the organic mill base on the inorganic sheet is bigger, makes the luminance brightness of the pearly pigment of generation that bigger loss arranged.Simultaneously, the pearly pigment that is prepared by this mode because a large amount of use organic dye, for the environment of human survival huge destruction is arranged, so the large-scale production of this product will be limited.
Seek environmental protection and produce the blue and relevant pearly pigment of high chroma reliably, become the challenge problem of fine chemistry industry enterprise.Merck KGaA company has disclosed with chemical deposition in USP 3951679 and has prepared Prussian blue (Fe
4[Fe (CN)

3) film.This method employing indirect method is at mica or be coated with TiO
2Or ZrO
2The surface of natural mica form Prussian bluely, technology and process are complicated, introduce too much chemical substance simultaneously, and be all influential to the waste treatment and the environmental protection of producing.
In addition, U.S. Patent Application Publication US2009257816 discloses a kind of printing ink, and this printing ink contains tabular granules of pigments, and this tabular granules of pigments comprises pearlescent particles, and this pearlescent particles has and contains the coating that is selected from the material in the Prussian blue grade.How the coating that this application does not disclose pearlescent particles forms.
