Definitions
- the present invention relates to a new interference pigment
- pearlescent pigments comprising a mica core coated with a titanium oxide layer.
- the intensity and brilliance of interferential colors can be further improved by inter alia playing on the optical properties of the metal at heart.
- the present invention thus proposes a new interference pigment
- the present invention provides an interference pigment

- a first layer of a transparent dielectric material a transparent dielectric material
- a second discontinuous metallic layer a first layer of a transparent dielectric material
- this metal core made of a precious metal having a high level of reflectance, and preferably greater than that of aluminum, in at least part of the visible spectrum, the interferential colors gain in brightness and intensity compared to those obtained with a conventional interference pigment. This results in coated or massive pieces having a particular brilliance appreciated in the field of watchmaking, jewelery and cosmetics.
- the interference pigment has one or a suitable combination of the following characteristics: the metal core comprises a material chosen from gold, silver, rhodium and one of their alloys and, more preferably, chosen from gold, silver and one of their alloys; it comprises a third protective layer formed of a transparent dielectric material or a transparent resin; the dielectric material of the first layer and the third layer is selected from the T1O2, S1O2, Al2O3, MgF2, AlN, Ta 2 O, Si 3 N 4 ZnS, ZnO, ZrO 2, Cr 2 O3, CeO2, Y2O3, HfN, HfC, HfCte, La2O3, MgO, Sb2Os, SiO,
- the second metal layer comprises a material chosen from silver, gold, aluminum, titanium, palladium, platinum, ruthenium, osmium, iridium, tin, chromium, iron, cobalt, nickel, copper, zinc, rhodium and one of their alloys;
- the metal core has a mean transverse diameter of between 2 and 300 ⁇ , preferably between 5 and 100 ⁇ and more preferably between 10 and 30 ⁇ , and a mean thickness of between 20 and 1000 nm and, preferably, between 300 and 500 nm ;
- the first layer has a thickness of between 50 and 500 nm and, preferably, between 300 and 400 nm;
- the second layer and the third layer have a thickness of between 1 and 30 nm and preferably between 1 and 10 nm;
- the second layer is in the form of particles arranged at intervals.
- the present invention also relates to a piece and, in particular to a trim piece, for the watch or jewelery industry comprising interferential pigments as described above.
- the part comprises a coating comprising interferential pigments or comprises in bulk interference pigments.
- the present invention also relates to the watch or jewel comprising the piece with the interference pigments.
- FIG. 1 shows schematically the different layers of the interference pigment according to the invention.
- FIG. 2 schematically represents the optical paths of the light through the interference pigment according to the invention.
- the present invention relates to a multilayer interference pigment comprising a core made of a pure precious metal or alloyed such as gold, silver, platinum, palladium, ruthenium, rhodium, lime. osmium or iridium. These metals have a reflectance level greater than 70%, or even greater than 80 or even 90% in all or part of the visible spectrum (380 nm - 780 nm).
- the metals chosen are, preferably, rhodium, gold, silver or one of their alloys and, more preferably, gold, silver or one of their alloys.
- Gold has a high reflectance for wavelengths greater than 550 nm. It is therefore preferred when warm colors (red, yellow) are desired.
- Silver on the other hand, has a high reflectance over a wider range of the visible spectrum, which also makes it possible to obtain bluish and green colors. In the case of an alloy, the choice is, for example, on an Ag-Pt alloy.
- the pigment 1 according to the invention shown in FIG. 1 comprises the metal core 2 coated with a first layer 3 of a dielectric material which forms the interference medium, itself coated with a second layer.
- the metal core 2 is in the form of an elongated flake having a mean transverse diameter D of between 2 and 300 ⁇ , preferably between 5 and 100 ⁇ and more preferably between 10 and 30 ⁇ . It has a mean thickness E of between 20 and 1000 nm and preferably between 300 and 500 nm.
- the flake form factor i.e. the ratio of the average transverse diameter to the average thickness is between 5 and 1000 and preferably between 10 and 500.
- the first layer 3 comprises a transparent dielectric material which may, for example, be T1O 2, SiO 2, Al 2 O 3, MgF 2, AlN, Ta 2 O 5 , Si 3 N 4 , ZnS, ZnO, ZrO 2 , Cr 2 O 3, CeO 2 , Y 2 O 3, HfN, HfC, HfO 2. , La 2 O 3, MgO, SD 2 O 3, SiO, Se 2 O 3, SnO 2, or WO 3, with a preference for SiO 2.
- This layer has a thickness between 50 and 500 nm and preferably between 300 and 400 nm, the thickness and the refractive index of the dielectric material being selected according to the desired interference color.
- the second layer 4 is formed of a metal or a metal alloy for reflecting light on the surface of the interference pigment.
- the metal is preferentially chosen from silver, gold, aluminum, titanium, palladium, platinum, ruthenium, rhodium, osmium, iridium, tin, chromium and iron. , cobalt, nickel, copper, zinc, rhodium and one of their alloys. It is more preferably chosen from silver, gold, aluminum, rhodium and one of their alloys.
- This layer has a thickness of between 1 and 30 nm and preferably between 1 and 10 nm. The layer is configured to allow transmission of a portion of the incident light beam to the metal core.
- the particles are preferably arranged at intervals with a space between particles of the order of a few nanometers. It is understood that such a second discontinuous metal layer allows both to reflect a portion of the light beam and to transmit another portion of this beam on the metal core.
- the optional third protective layer 5 is intended to protect the second metal layer from oxidation or wear.
- This layer is preferably made of a transparent dielectric material such as T1O2, S1O2, Al2O3, MgF 2, AlN, Ta 2 O, the SISN, ZnS, ZnO, ZrO 2, Cr 2 O3, CeO2, Y2O3, HfN, HfC, Hf ⁇ 2, La 2 O 3, MgO, SD 2 O 3, SiO, Se 2 O 3, SnO 2, WO 3 or in a clear resin.
- This layer has a thickness of between 1 and 30 nm and preferably between 1 and 10 nm.
- the present invention does not exclude introducing intermediate layers between the metal core and the first layer and / or between the first and second layers in order to increase the adhesion between the various constituent layers of the interference pigment.
- part of the incident light ray is reflected on the outer metal layer 4 while another part is transmitted and reflected on the metal core 2.
- the difference in trajectory between the two reflected beams creates by interferential effect a color with shades depending on the viewing angle.
- the metal core can be made from a sheet, for example gold or silver, with the outer layers deposited by CVD, PVD, electrochemistry or electrolessly, the whole being subsequently ground.
- the multilayer pigment may also be manufactured from flakes obtained by wet or dry chemistry or by spraying, optionally crushed before being coated.
- the pigment powder thus obtained can be dispersed in a suitable medium depending on the application. It can thus be used in formulations for paints, inks, cosmetics and, in general, in coating formulations. It is also conceivable to use the pigment powder as it is. In this configuration, the previously deposited powder is compacted on a substrate and then sintered uniformly or selectively under the effect of a local heat input for example by laser. This results in a dense coating covering all or part of the substrate. It is also conceivable to produce solid parts by compaction and densification of the pigment powder. It is also conceivable to produce massive pieces by additive manufacturing.
- the pigments can be used after dispersion in a suitable medium or as such for coating or decorating a piece of clothing (dial, bezel, caseband, bottom, clasp, ...) or to make a massive piece of clothing (dial, needle, index, pusher, etc.).
- a first S1O2 coating layer with a thickness of 330 nm
- the mass percentage of gold is 79.01%, ie. higher than the 75% required for 18-carat gold.
- the metal core can also be made in other precious alloys to achieve legal titles such as, for example, the Pd500 or the Pt900.
- Second layer also called metal layer
