- an object of the present invention is to make available an article that is provided with the product obtained using the composition according to the invention.
- a composition that comprises at least one resin chosen from among acetate resins, polyester resins, melamine resins, urea-formaldehyde resins, polyamide resins and ABS and at least one derivative compound of at least one element chosen from: Fe, Al, Sn, In, Ti, Zn.
- said at least one resin is urea- formaldehyde resin
- said at least one element is chosen from between Al and Fe.
- said derivative compound of Fe, Al, Sn, In, Ti, Zn is a salt, a complex, or an oxide of said element, for example an oxide chosen from the group: Fe2 ⁇ 3, AI2O3, SnO, InO, Ti ⁇ 2, ZnO.
- said compound is advantageously chosen from between Fe2U3 and AI2O3.
- composition according to the invention which comprises at least one resin chosen from amongst acetate resins, polyester resins, melamine resins, urea-formaldehyde resins, polyamide resins and ABS and at least one derivative compound of at least one element chosen from the group Fe, Al, Sn, In, Ti, Zn, is indicated, for reasons of simplicity, as basic composition and can of course further comprise fillers and additives of a known type, such as for example plastifiers, potato flour, powdered horn, and the like.
- the basic composition envisages that the resin will be present in amounts ranging between 30 wt% and 90 wt% with respect to the total weight of the end composition, preferably comprised between 45 wt% and 75 wt% and in particular comprised between 60 wt% and 70 wt% with respect to the total weight of the end composition.
- the basic composition envisages that said derivative compound of at least one element chosen from: Fe, Al, Sn, In, Ti, Zn will be present in amounts ranging between 0.05 wt% and 10 wt% with respect to the total weight of the end composition, preferably comprised between 0.05 wt% and 5 wt% and, in particular, comprised between 0.1 wt% and 1 wt% with respect to the total weight of the end composition.
- the composition according to the present invention is prepared using a process which comprises the following steps: a) mixing said at least one resin chosen from among acetate resins, polyester resins, melamine resins, urea-formaldehyde resins, polyamide resins and ABS, and extenders, additives, fillers to obtain a mixed powder; b) adding and mixing said at least one derivative compound of at least one element chosen from: Fe, Al, Sn, In, Ti, Zn to said mixed powder to obtain a basic mix; and c) treating said basic mix according to known techniques to obtain finished products of different kinds, according to the use to which they are to be put.
- the process described above is used in the case where a dry basic mix is required. Alternatively, it is possible to produce a wet basic mix by inserting between said step a) and said step b) an intermediate step ab) which requires the addition of the necessary liquid components.
- composition according to the invention it is possible to prepare finished products, for example buckles, buttons, pins, screws, joints, labels, inserts made of suitable material, name-plates, and the like, which may be associated, in a simple way, to articles of various kinds, for example articles of the clothing or furnishing sectors. Said products, once they are associated to said articles, enable identification in a unique way of the origin of the articles themselves.
- the composition according to the invention comprises, at different concentrations, at least one derivative of at least one of said elements, Fe, Al, Sn, In, Ti, Zn, which is characterized by a resonance frequency that can be detected by suitable apparatus.
- the composition according to the invention is used for the preparation of a series of buttons.
- the aforesaid buttons are associated to a garment, for example a jacket, of which it is intended to identify and be able to verify the origin.
- the authorized producer of the jacket, or the creator of the model decides that at least one of the buttons applied on the jacket will be made using the composition according to the invention. Should it be necessary to check jackets that are apparently the same but where the origin thereof is in question, it will be sufficient -to check the jackets using the appropriate apparatus, which also forms the subject of the present invention.
- the official producer for example of a certain signed or stamped garment can thus decide to apply any accessory produced using the composition forming the subject of the invention to said garment.
- the producer is in all cases able to establish whether it is his own original garment or a non-authorized copy.
- the products obtained using the compositions according to the invention are suitable for being associated, according to various modalities, to articles widely available on the market which require checks in regard to their possible imitations.
- the products obtained via the compositions according to the invention are, for example, buckles, buttons, name-plates, labels, screws, small chains, joints, and the like.
- the product is obtained by adding to the basic resin predefined and variable amounts of at least one derivative of the aforesaid elements. Using suitable apparatus and/ or an appropriate verification tool, it is therefore possible to identify precisely, reliably and confidentially the particular production lot, and consequently the origin and originality of the article in which said product is inserted or to which it is associated.
- the solution according to the invention presents numerous advantages.
- - The system is economically advantageous as compared to the conventional systems currently adopted and hence proves competitive.
- - The basic composition can be rapidly modified and even agreed upon with the customer who is the manufacturer of the finished article, without the appearance of the product and hence the article being in any way modified.
- - It is possible to personalize the product and hence adapt it to each article to which it is to be associated.
- Application of the product on the finished article can normally be performed using the same production machinery normally employed without any additional expenses.
- buttons to be applied to clothing articles all the buttons will be applied when the articles are made, i.e., both the "normal" buttons and the buttons made using the composition forming the subject of the present invention, will be applied at the same time without, for example, the maker being able to distinguish the accessory that will enable control and verification of the garment.
- a transponder is inserted in just one button that is applied subsequently on the garment, thus creating one variable more with respect to the possibility of the garment being reproduced in a non-authorized way.
- a suitable piece of equipment apparatus for detecting the product according to the invention is based upon the physical principle, used in the verification system, which, in brief, consists in measuring the decay of the residual currents induced in the metal parts (decay of Foucault currents). Notwithstanding the very small amounts of current involved in the signal measured, a series of appropriate solutions applied enable measurements that are reliable, repetitive and useful for a reliable identification of the article and of the period of manufacture thereof.
- the present invention there follows a detailed description of a process for preparing a product in the form of a button, using the composition according to the invention.
- the finished product in this case a button, is obtained via the following steps:
- Said neutral paste is inserted into fork mixers with the addition of ingredients that are to be dispersed for a period that can vary according to the amount of paste involved.
- ingredients are the ones that will be subsequently sought using suitable instrumentation, and in particular are derivative compounds of at least one element chosen from the group: Fe, Al, Sn, In, Ti, Zn. Colouring the paste thus prepared in amounts according to the subsequent preparation of the unit in question. - Following a sequence of manipulation of the coloured paste in order to reproduce a working drawing (staining of the button) to obtain finally a coloured mould having a cylindrical shape that must be embedded in polythene to prevent loss of water by evaporation.
- EXAMPLE 3 Basic composition: 15 wt% of urea-formaldehyde resin with cellulose fillers 45 wt% of urea-formaldehyde resin
