Description Description

Domaine de l'invention Field of the invention

[0001] L'invention se rapporte ä un element d'horlogerie comprenant un Substrat et au moins un premier element de decor comprenant au moins un premier materiau photoluminescent destine ä donner un aspect phosphorescent lorsque l'element est place dans l'obscurite. La presente invention concerne egalement une piece d'horlogerie comprenant un tel element. [0001] The invention relates to a timepiece element comprising a substrate and at least one first decorative element comprising at least one first photoluminescent material intended to give a phosphorescent appearance when the element is placed in the dark. The present invention also relates to a timepiece comprising such an element.

Arriere-plan de l'invention Background of the invention

[0002] On connait par exemple l'utilisation d'un tel materiau photoluminescent pour realiser des revetements destines ä recouvrir les aiguilles ou les index d'une montre, afin que lesdites aiguilles ou lesdits index soient lumineux et apparaissent dans l'obscurite. [0002] For example, the use of such a photoluminescent material is known to produce coatings intended to cover the hands or the indexes of a watch, so that the said hands or the said indexes are luminous and appear in the dark.

[0003] Le brevet CH 697 210 decrit un cadran comprenant une couche semi-transparente dont la face arriere comprenddes cavites remplies de pigments phosphorescents qui permettent de faire apparaitre sous la couche semi-transparenteun decor visible dans l'obscurite. [0003] Patent CH 697 210 describes a dial comprising a semi-transparent layer, the rear face of which comprises cavities filled with phosphorescent pigments which make it possible to reveal under the semi-transparent layer a decor visible in the dark.

[0004] Toutefois, meme si les decors comprenant des pigments phosphorescents utilises sur un element d'horlogerie sont senses ne pas etre perceptibles lorsque l'element decore est expose ä la lumiere du jour, ces decors apparaissent malgre tout, en particulier pour un oeil professionnel averti. Les decors phosphorescents qui transparaissent ä la lumiere du jour nuisent donc ä l'esthetisme de la piece d'horlogerie, ce qui n'est pas acceptable, en particulier pour des pieces d'horlogerie haut de gamme. [0004] However, even if the decorations comprising phosphorescent pigments used on a timepiece element are supposed not to be perceptible when the decorated element is exposed to daylight, these decorations nevertheless appear, in particular for an eye knowledgeable professional. The phosphorescent decorations which show through in daylight therefore harm the aesthetics of the timepiece, which is not acceptable, in particular for high-end timepieces.

Resume de l'invention Summary of the invention

[0005] La presente invention a pour but de remedier ä ces inconvenients en proposant un element d'horlogerie comprenant un materiau photoluminescent destine ä donner dans l'obscurite un aspect phosphorescent, ledit materiau photoluminescent etant masque lorsque l'element est expose ä la lumiere, afin d'ameliorer son aspect esthetique. [0005] The object of the present invention is to remedy these drawbacks by proposing a timepiece element comprising a photoluminescent material intended to give a phosphorescent appearance in the dark, said photoluminescent material being masked when the element is exposed to light. , in order to improve its aesthetic appearance.

[0006] A cet effet, l'invention se rapporte ä un element d'horlogerie comprenant un Substrat et au moins un premier element de decor comprenant au moins un premier materiau photoluminescent destine ä donner un aspect phosphorescent. [0006] To this end, the invention relates to a timepiece element comprising a substrate and at least one first decorative element comprising at least one first photoluminescent material intended to give a phosphorescent appearance.

[0007] Selon l'invention, ledit element d'horlogerie comprend un second element de decor comprenant au moins un second materiau, ledit second materiau etant metallique, destine ä donner un aspect metallique, ou variochromique, destine ä donner une couleur variant sous l'effet d'un Stimulus, ledit premier element de decor et ledit second element de decor etant agences Tun par rapport ä l'autre sur le Substrat pour former un decor d'aspect metallique ou d'une couleur variant sous l'effet d'un Stimulus lorsque ledit element est expose ä la lumiere et d'aspect phosphorescent lorsque ledit element est dans l'obscurite. [0007] According to the invention, said timepiece element comprises a second decorative element comprising at least one second material, said second material being metallic, intended to give a metallic appearance, or variochromic, intended to give a color varying under the effect of a Stimulus, said first element of decor and said second element of decor being arranged one with respect to the other on the Substrate to form a decor of metallic appearance or of a color varying under the effect of a Stimulus when said element is exposed to light and of phosphorescent appearance when said element is in the dark.

[0008] Ainsi, lorsque l'element d'horlogerie selon l'invention est expose ä la lumiere, le premier materiau photoluminescent depose sur ledit element disparait au profit d'un aspect metallique apporte par le second materiau. [0008] Thus, when the timepiece element according to the invention is exposed to light, the first photoluminescent material deposited on said element disappears in favor of a metallic appearance provided by the second material.

[0009] En consequence, l'element d'horlogerie expose ä la lumiere presente un aspect esthetique ameliore, le premier materiau photoluminescent d'aspect inesthetique etant alors masque, tout en presentant un bei aspect phosphorescent dans l'obscurite. [0009] Consequently, the timepiece element exposed to the light presents an improved aesthetic appearance, the first photoluminescent material of unsightly appearance then being masked, while presenting a beautiful phosphorescent appearance in the dark.

[0010] La presente invention concerne egalement une piece d'horlogerie comprenant un tel element. The present invention also relates to a timepiece comprising such an element.

Description detaillee des modes de realisation preferes Detailed description of preferred embodiments

[0012] La presente invention concerne un element d'horlogerie comprenant un Substrat et au moins un premier element de decor comprenant au moins un premier materiau photoluminescent destine ä donner un aspect phosphorescent dans l'obscurite. [0012] The present invention relates to a timepiece element comprising a substrate and at least one first decorative element comprising at least one first photoluminescent material intended to give a phosphorescent appearance in the dark.

[0013] Un tel element d'horlogerie peut etre un cadran, une aiguille, un index, une lunette, une glace, cöte cadran ou cöte fond, une boite de montre, etc. [0013] Such a horological element can be a dial, a hand, an index, a bezel, a crystal, on the dial side or on the back side, a watch case, etc.

[0014] Le substrat peut etre opaque ou semi-transparent, voire transparent. Un Substrat opaque peut etre par exemplemetallique. II peut etre en laiton, ä base d'or, jaune ou blanc, ou d'argent, ou tout autre metal ou alliage, precieux ou non, approprie. [0014] The substrate can be opaque or semi-transparent, or even transparent. An opaque Substrate may for example be metallic. It can be made of brass, based on gold, yellow or white, or silver, or any other suitable metal or alloy, precious or not.

[0015] Les Substrats semi-transparents et transparente peuvent etre du verre, du verre saphir, une resine acrylique outoute autre resine appropriee. [0015] The semi-transparent and transparent Substrates can be glass, sapphire crystal, an acrylic resin or any other suitable resin.

[0016] Conformement ä la presente invention, l'element d'horlogerie comprend un second element de decor comprenant au moins un second materiau, ledit second materiau etant metallique, destine ä donner un aspect metallique, nacre ou destine ä donner un effet nacre (particules de verres revetues de couche interferentielles) ou variochromique, destine ä donner une couleur variant sous l'effet d'un Stimulus, ledit premier element de decor et ledit second element de decor etant agences Tun par rapport ä l'autre sur le substrat pour former un decor d'aspect metallique ou d'une couleur variant sous l'effet d'un Stimulus lorsque ledit element est expose ä la lumiere et d'aspect phosphorescent lorsque ledit element est dans l'obscurite. [0016] In accordance with the present invention, the timepiece element comprises a second decorative element comprising at least one second material, said second material being metallic, intended to give a metallic, mother-of-pearl appearance or intended to give a mother-of-pearl effect ( glass particles coated with an interferential) or variochromic layer, intended to give a color varying under the effect of a Stimulus, said first element of decor and said second element of decor being arranged one with respect to the other on the substrate to forming a decor of metallic appearance or of a color varying under the effect of a Stimulus when said element is exposed to light and of phosphorescent appearance when said element is in the dark.

[0017] D'une maniere preferee, le premier materiau est constitue de pigments photoluminescents, de preference du type SrAI2O4:Eu2+,Dy3+,B3+ ou MAI2Si2O8:Eu2+ (M=Ba,Sr,Ca). [0017] In a preferred way, the first material consists of photoluminescent pigments, preferably of the SrAl2O4:Eu2+,Dy3+,B3+ or MAI2Si2O8:Eu2+ (M=Ba,Sr,Ca) type.

[0018] D'une maniere generale, la teneur massique en pigments dans le premier element de decor peut etre comprise entre 1% et 70%, avec ä 1% une transparence de la couche du premier element de decor, une intensite lumineuse faible ä t=5mn de l'ordre de 10 mCd/m2 mesure selon ISO 17514, et ä 70% une opacite de la couche du premier element de decor, une intensite lumineuse de l'ordre de500mCd/m2 ä t=5mn mesure selon ISO 17514. Idealement la teneur massique en pigment est de 50% pour avoir un compromis entre un bon etat de surface du premier element de decor et l'intensite lumineuse recherchee. [0018] In general, the mass content of pigments in the first decorative element can be between 1% and 70%, with at 1% a transparency of the layer of the first decorative element, a low light intensity at t=5mn of the order of 10 mCd/m2 measured according to ISO 17514, and at 70% opacity of the layer of the first decorative element, a luminous intensity of the order of 500mCd/m2 at t=5mn measured according to ISO 17514 Ideally, the mass content of pigment is 50% to achieve a compromise between a good surface condition of the first decorative element and the desired light intensity.

[0019] Dans la presente description, on appelle „materiau metallique" un materiau au moins partiellement metallique pouvant comprendre des particules non metalliques et des particules metalliques ainsi qu'un materiau entierement metallique. In the present description, the term "metallic material" means an at least partially metallic material which may include non-metallic particles and metallic particles as well as an entirely metallic material.

[0020] Selon une premiere Variante de l'invention, le second materiau du second element de decor est present sous la forme de particules dispersees dans le second liant. According to a first variant of the invention, the second material of the second decorative element is present in the form of particles dispersed in the second binder.

[0021] Selon un premier mode de realisation de l'invention represente sur la figure 1, le decor est bicouche, forme d'une premiere couche au moins semi-transparente, voire transparente, constituant le premier element de decor 1 et comprenant un premier liant dans lequel sont disperses, comme premier materiau, des pigments photoluminescents 2, et d'une seconde couche constituant le second element de decor 3 et comprenant un second liant dans lequel sont dispersees, comme second materiau, des particules 4 metalliques ou metallisees pelliculantes, ou nacrees ou des particules variochromiques, ladite seconde couche 3 etant disposee entre le substrat 6 et la premiere couche 1 destinee ä etre au plus pres d'un utilisateur. According to a first embodiment of the invention shown in Figure 1, the decor is two-layer, in the form of a first layer at least semi-transparent, or even transparent, constituting the first decorative element 1 and comprising a first binder in which are dispersed, as first material, photoluminescent pigments 2, and a second layer constituting the second decorative element 3 and comprising a second binder in which are dispersed, as second material, metallic or metallized film particles 4, or nacreous or variochromic particles, said second layer 3 being placed between the substrate 6 and the first layer 1 intended to be as close as possible to a user.

[0022] La premiere couche semi-transparente ou transparente au spectre visible constituant le premier element de decor1 presente de preference une epaisseur comprise entre 0.1 mm et 2 mm. The first layer semi-transparent or transparent to the visible spectrum constituting the first element of decor1 preferably has a thickness between 0.1 mm and 2 mm.

[0023] Dans le cas particulier du premier mode de realisation selon lequel la premiere couche est semi-transparente outransparente, ladite premiere couche comprend entre 1 % et 10% en poids de pigments photoluminescents tels que definis ci-dessus. In the particular case of the first embodiment in which the first layer is semi-transparent or transparent, said first layer comprises between 1% and 10% by weight of photoluminescent pigments as defined above.

[0024] La seconde couche constituant le second element de decor 3 presente de preference une epaisseur <100mu The second layer constituting the second decorative element 3 preferably has a thickness <100mu

[0025] Dans la seconde couche 3, les particules sont choisies afin de reflechir avantageusement la lumiere pour rendre les particules phosphorescentes indetectables ä l'oeil. II s'agit soit de particules 4 metalliques ou metallisees, pelliculantes, qui creent un effet miroir pour une reflexion optimale de la lumiere. Elles sont avantageusement constituees de lamelles fines metalliques de granulometrie de preference comprise entre 10 pm et 500 pm, et (par exemple aluminium, bronze, or, argent) soit de de particules inorganiques (oxyde d'aluminium, dioxyde de silicium et borosilicates) metallisees sous vide (par exemple par PVD, les differentes couches deposees par PVD pouvant permettre avantageusement de creer des couleurs interferentielles donnant des aspects irises ou nacres). [0025] In the second layer 3, the particles are chosen in order to reflect the light advantageously to make the phosphorescent particles undetectable to the eye. These are either metallic or metallized, film-coating particles 4, which create a mirror effect for optimum reflection of light. They are advantageously made up of thin metal strips with a particle size preferably between 10 μm and 500 μm, and (for example aluminum, bronze, gold, silver) or of inorganic particles (aluminum oxide, silicon dioxide and borosilicates) metallized under vacuum (for example by PVD, the various layers deposited by PVD being able to advantageously make it possible to create interferential colors giving iridescent or pearly aspects).

[0026] Les particules variochromiques sont constituees au moins de pigments de type photochromique ou de pigments de type thermochromique tels que les nanoparticules ä effet de transition de spins. [0026] The variochromic particles consist of at least pigments of the photochromic type or of pigments of the thermochromic type such as nanoparticles with a spin transition effect.

[0027] La premiere couche au moins semi-transparente constituant le premier element de decor 1 ä base de pigmentsphotoluminescents 2 et la seconde couche constituant le second element de decor 3 ä base de particules 4 metalliques ou variochromiques sont superposees, la premiere couche 1 etant destinee ä etre au plus pres de l'utilisateur. Ainsi, le decor forme par la Superposition des premier et second elements de decor 1, 3 presente un aspect metallique ou une couleur variant sous l'effet d'un Stimulus lie au materiau variochromique, donne par le second element de decor 3 apparaissant sous le premier element de decor 1 transparent lorsque l'element d'horlogerie est expose ä la lumiere, et le decor presente un aspect phosphorescent donne par le premier element de decor 1 positionne au plus pres de l'utilisateur, lorsque l'element d'horlogerie est dans l'obscurite. The at least semi-transparent first layer constituting the first decorative element 1 based on photoluminescent pigments 2 and the second layer constituting the second decorative element 3 based on metallic or variochromic particles 4 are superimposed, the first layer 1 being designed to be closer to the user. Thus, the decor formed by the superposition of the first and second decor elements 1, 3 has a metallic appearance or a color varying under the effect of a Stimulus linked to the variochromic material, given by the second decor element 3 appearing under the first decor element 1 transparent when the clockwork element is exposed to light, and the decor has a phosphorescent appearance given by the first decor element 1 positioned as close as possible to the user, when the clockwork element is in darkness.

[0028] Selon un deuxieme mode de realisation de l'invention represente sur la figure 2, le decor est bicouche, forme d'une premiere couche constituant le premier element de decor 1 et comprenant un premier liant dans lequel sont disperses, According to a second embodiment of the invention shown in Figure 2, the decor is two-layer, in the form of a first layer constituting the first decorative element 1 and comprising a first binder in which are dispersed,

comme premier materiau, des pigments photoluminescents 2 tels que definis ci-dessus, et d'une seconde couche transparente constituant le second element de decor 3 et comprenant un second liant dans lequel sont dispersees, comme second materiau, des particules 4 metalliques ou metallisees non pelliculantes ou des particules variochromiques, ladite premiere couche 1 etant disposee entre le Substrat 6 et la seconde couche 3 destinee ä etre au plus d'un utilisateur. as first material, photoluminescent pigments 2 as defined above, and a second transparent layer constituting the second decorative element 3 and comprising a second binder in which are dispersed, as second material, metallic or metallized particles 4 not films or variochromic particles, said first layer 1 being placed between the substrate 6 and the second layer 3 intended to be at most one user.

[0029] La premiere couche constituant le premier element de decor 1 presente de preference une epaisseur comprise entre 0.1 mm et 2 mm. Dans ce mode de realisation, la premiere couche n'est pas necessairement transparente ou semi-transparente. The first layer constituting the first decorative element 1 preferably has a thickness of between 0.1 mm and 2 mm. In this embodiment, the first layer is not necessarily transparent or semi-transparent.

[0030] La seconde couche transparente constituant le second element de decor 3 presente de preference une epaisseur comprise <100mu [0030] The second transparent layer constituting the second decorative element 3 preferably has a thickness of <100mu

[0031] Les particules 4 metalliques ou metallisees non pelliculantes sont par exemple les particules metallisees decrites ci-dessus pour le premier mode de realisation, mais pour lesquelles par exemple un acide gras insature a ete utilisependant le broyage des particules afin de modifier leur tension de surface. Cela permet egalement de mieux repartir les particules dans la couche et d'ameliorer la resistance ä l'abrasion. [0031] The non-film-forming metallic or metallized particles 4 are, for example, the metallized particles described above for the first embodiment, but for which, for example, an unsaturated fatty acid has been used during the grinding of the particles in order to modify their tension of surface. This also makes it possible to better distribute the particles in the layer and to improve the resistance to abrasion.

[0032] Dans le cas particulier du deuxieme mode de realisation selon lequel la seconde couche 3 est transparente, ladite seconde couche transparente comprend moins de 5 % en poids de particules metallisees afin d'obtenir cette transparence le pourcentage etant sensiblement identique pour les particules variochromiques. In the particular case of the second embodiment according to which the second layer 3 is transparent, said second transparent layer comprises less than 5% by weight of metallized particles in order to obtain this transparency, the percentage being substantially identical for the variochromic particles .

[0033] La premiere couche constituant le premier element de decor 1 ä base de pigments photoluminescents 2 et la seconde couche transparente constituant le second element de decor 3 ä base de particules 4 metalliques ou variochromiques sont superposees, la seconde couche 3 etant destinee ä etre au plus pres de l'utilisateur. Ainsi, le decor forme par la Superposition des premier et second elements de decor 1,3 presente un aspect metallique ou une couleur variant sous l'effet d'un Stimulus lie au materiau variochromique, donne par le second element de decor 3 positionne au plus pres de l'utilisateur lorsque l'element d'horlogerie est expose ä la lumiere, et le decor presente un aspect phosphorescent donne par le premier element de decor 1 apparaissant sous le second element de decor 3 transparent, lorsque l'element d'horlogerie est dans l'obscurite. The first layer constituting the first decorative element 1 based on photoluminescent pigments 2 and the second transparent layer constituting the second decorative element 3 based on metallic or variochromic particles 4 are superimposed, the second layer 3 being intended to be closer to the user. Thus, the decor formed by the superimposition of the first and second decor elements 1,3 presents a metallic appearance or a color varying under the effect of a Stimulus linked to the variochromic material, given by the second decor element 3 positioned at most close to the user when the clockwork element is exposed to light, and the decor has a phosphorescent appearance given by the first decor element 1 appearing under the second decor element 3 transparent, when the clockwork element is in darkness.

[0034] Selon un troisieme mode de realisation de l'invention represente sur la figure 3, le decor est monocouche, destine ä etre au plus pres d'un utilisateur, et forme d'une troisieme couche 8 deposee sur le Substrat 6 du cöte de l'utilisateur pour etre au plus pres de l'utilisateur, et comprenant un troisieme liant dans lequel sont dispersees des particules 4 metalliques ou metallisees ou des particules variochromiques formant le second element de decor 3 et revetues de pigments photoluminescents 2 formant le premier element de decor 1. [0034] According to a third embodiment of the invention shown in Figure 3, the decor is single layer, intended to be closer to a user, and form a third layer 8 deposited on the substrate 6 on the of the user to be as close as possible to the user, and comprising a third binder in which are dispersed metallic or metallized particles 4 or variochromic particles forming the second decorative element 3 and coated with photoluminescent pigments 2 forming the first element of decor 1.

[0035] Pour cela, on utilise de preference des particules 4 metalliques ou metallisees ou nacrees ou des particules variochromiques du type defini ci-dessus, de granulometrie comprise entre 100 pm et 500 pm, et de preference compriseentre 100 pm et 200 pm. Les pigments photoluminescents 2 du type defini ci-dessus ont de preference une taille inferieureä 10 pm. On realise au prealable une dispersion de pigments photoluminescents 2 comprenant au poids 5 ä 30% de pigments photoluminescents dans une matrice liquide polymere/solvant. Differents procedes sont ensuite possibles : For this, use is preferably made of metallic or metallized or nacreous particles 4 or variochromic particles of the type defined above, with a particle size between 100 μm and 500 μm, and preferably between 100 μm and 200 μm. The photoluminescent pigments 2 of the type defined above preferably have a size of less than 10 μm. A dispersion of photoluminescent pigments 2 comprising by weight 5 to 30% of photoluminescent pigments in a liquid polymer/solvent matrix is produced beforehand. Different methods are then possible:

- la dispersion de pigments photoluminescents formee est directement pulverisee sur les particules metalliques, metallisees ou variochromiques qui sont etalees sur une plaque, puis sechees. Le tout est ensuite broye par broyage cryogenique afin que les particules eventuellement collees entre elles puissent etre separees. - the dispersion of photoluminescent pigments formed is directly sprayed on the metallic, metallized or variochromic particles which are spread on a plate, then dried. The whole is then ground by cryogenic grinding so that any particles stuck together can be separated.

- on melange les particules metalliques, metallisees ou variochromiques dans la dispersion de pigments photoluminescents puis on introduit le melange obtenu dans un atomiseur permettant de secher rapidement les pigments photoluminescents autour des particules metalliques, metallisees ou variochromiques. Le sechage peut egalement etre realise dans des sechoirs ä plateau („tray drying") ou par sechage ä lit fluidise („fluid bed drying") puis l'ensemble est rebroye par broyage cryogenique. Les particules obtenues sont ensuite dispersees dans le troisieme liant. - the metallic, metallized or variochromic particles are mixed in the dispersion of photoluminescent pigments and then the mixture obtained is introduced into an atomizer making it possible to quickly dry the photoluminescent pigments around the metallic, metallized or variochromic particles. The drying can also be carried out in tray dryers ("tray drying") or by fluidized bed drying ("fluid bed drying"), then the whole is ground again by cryogenic grinding. The particles obtained are then dispersed in the third binder.

[0036] Une autre alternative demande la preparation suivante des pigments ä effets metallises ou nacres. Ceux-ci sontrevetus d'un film pre-polymere fin et transparent (entre 20-50 microns) par un traitement en bain (melange de 80% d'unsolvant, 15 % de monomeres, 2% de durcisseurs et 3% d'additifs). Les pigments traites sont ensuite melanges par friction dans un broyeur ä billes avec une dispersion de pigments phosphorescents. [0036] Another alternative requires the following preparation of pigments with metallic or pearl effects. These are coated with a thin and transparent pre-polymer film (between 20-50 microns) by a bath treatment (mixture of 80% solvent, 15% monomers, 2% hardeners and 3% additives ). The treated pigments are then mixed by friction in a ball mill with a dispersion of phosphorescent pigments.
