Abstract

The method involves preparing an object, to be decorated, by depositing a film of a sublimable pigmented composition e.g. polyvinyl acetate, on the object. The prepared object is soaked in a non-ferrous metal alloy bath maintained at a nominal temperature for activating the composition. The bath is formed by an alloy of antimony, bismuth, lead, tin and cadmium and the composition has an insoluble colorant or a metallic powder. An independent claim is also included for an equipment for the implementation of a three-dimensional article decoration method.

Description

PROCÉDÉ DE DÉCORATION D'UN ARTICLE ET ÉQUIPEMENT POUR LAMETHOD FOR DECORATING AN ARTICLE AND EQUIPMENT FOR

MISE EN UVRE DE CE PROCÉDÉ La présente invention concerne la décoration d'articles par le transfert de substances thermoactivables, telles que des encres thermoactivables, notamment des encres sublimables ou encore des substances de dorure.  The present invention relates to the decoration of articles by the transfer of thermo-activatable substances, such as heat-activatable inks, in particular sublimable inks or gilding substances.

Le principe général est connu par plusieurs brevets de 10 l'art antérieur, et en particulier de brevets déposés par le breveté.  The general principle is known by several patents of the prior art, and in particular patents filed by the patentee.

Les brevets US5665458, US4314813 et DE19709496 décrivent des procédés de transfert par contact, selon une technique se rapprochant de celle d'un tampon. Un substrat porte des fibres floquées pour retenir une encre à transférer sur une surface à décorer. Cette solution n'est pas satisfaisante, car elle ne permet pas de décorer des surfaces gauches et nécessite l'application d'une pression à l'aide d'une matrice épousant le profil de la surface à décorer.  US5665458, US4314813 and DE19709496 disclose contact transfer methods, using a technique approaching that of a buffer. A substrate carries flocked fibers to retain ink to be transferred to a surface to be decorated. This solution is not satisfactory because it does not decorate left surfaces and requires the application of pressure using a matrix matching the profile of the surface to be decorated.

La demande de brevet internationale WO2005000602 concerne, selon son acception la plus générale, un procédé de décoration d'un article comportant une étape de préparation d'une feuille de transfert par impression avec au moins une encre thermoactivable, une étape de transfert par application de ladite feuille sur l'article à décorer, et par chauffage de cet ensemble, caractérisé en ce que ladite feuille de transfert est constituée en un matériau floqué et une étape de transfert où la feuille de transfert forme autour de l'article à décorer une enveloppe étanche raccordée à une source de dépression.  The international patent application WO2005000602 concerns, in its most general sense, a method of decorating an article comprising a step of preparing a printing transfer sheet with at least one heat-activatable ink, a transfer step by application of said sheet on the article to be decorated, and by heating this assembly, characterized in that said transfer sheet is made of a flocked material and a transfer step where the transfer sheet forms around the article to decorate an envelope waterproof connected to a source of depression.

On connnait également la demande de brevet européen EP1022158 décrivant un procédé d'impression d'encre sur un article tridimensionnel. Ce procédé nécessite une succession d'opérations difficilement industrialisable et mettant en 2881988 2 oeuvre des interventions manuelles de rectification des décors et de nettoyage.  Also known was European Patent Application EP1022158 describing an ink printing process on a three-dimensional article. This process requires a succession of operations which is difficult to industrialize and which involves the manual intervention of rectification of the decorations and cleaning.

La présente invention vise à remédier aux inconvénients des solutions de l'art antérieur en proposant un procédé de décoration d'un article tridimensionnel comportant une étape de préparation de l'objet à décorer consistant à déposer sur ledit objet une pellicule d'une composition pigmentée sublimable, puis à procéder à un trempage de l'objet ainsi préparé dans un bain d'alliage de métaux non-ferreux maintenu à une température nominale pour l'activation de ladite composition sublimable.  The present invention aims at remedying the drawbacks of the solutions of the prior art by proposing a method for decorating a three-dimensional article comprising a step of preparing the object to be decorated consisting of depositing on said object a film of a pigmented composition. sublimable, and then to soak the object thus prepared in a bath of non-ferrous metal alloy maintained at a nominal temperature for the activation of said sublimable composition.

Selon une première variante, le bain est formé par un alliage à base d'antimoine, d'étain, de bismuth et de plomb. Selon une deuxième variante, le bain est formé par un alliage à base bismuth, plomb, étain et cadmium.  According to a first variant, the bath is formed by an alloy based on antimony, tin, bismuth and lead. According to a second variant, the bath is formed by an alloy based on bismuth, lead, tin and cadmium.

Selon une troisième variante, le bain est formé par un alliage de métaux non-ferreux comprenant du bismuth.  According to a third variant, the bath is formed by a non-ferrous metal alloy comprising bismuth.

Selon un mode de mise en oeuvre particulier, l'article à décorer est recouvert, avant le trempage dans le bain de métaux non-ferreux, par une pellicule de vernis.  According to a particular embodiment, the article to be decorated is covered, before soaking in the bath of non-ferrous metals, with a film of varnish.

Avantageusement, l'article à décorer est recouvert, avant le trempage dans le bain de métaux non-ferreux, par une pellicule de PVA.  Advantageously, the article to be decorated is covered, before soaking in the bath of non-ferrous metals, with a film of PVA.

De préférence, le chauffage pour l'activation de la composition sublimable pendant l'étape de transfert est assuré par un bain d'un alliage composé de bismuth, de plomb, d'étain, et de cadmium (Bi 50%, Pb 25%, Sn 12.5%, Cd 12.5%) dont le point de fusion est d'environ 70 C, maintenu à une température d'environ 190 C.  Preferably, the heating for the activation of the sublimable composition during the transfer step is provided by a bath of an alloy composed of bismuth, lead, tin, and cadmium (Bi 50%, Pb 25% , Sn 12.5%, Cd 12.5%) having a melting point of about 70 ° C., maintained at a temperature of about 190 ° C.

Selon un mode de mise en oeuvre particulier, la composition sublimable comprend des pigments ou des poudres métalliques.  According to a particular embodiment, the sublimable composition comprises pigments or metal powders.

L'invention concerne également un équipement pour la mise en oeuvre du procédé caractérisé en ce qu'il comporte un bac thermostaté contenant un bain d'alliage de métaux non-ferreux.  The invention also relates to equipment for carrying out the process characterized in that it comprises a thermostatically controlled tank containing a non-ferrous metal alloy bath.

Elle concerne également les articles décorés réalisés selon ce procédé.  It also relates to decorated articles made according to this method.
