Patents by Inventor Maurizio Ragnetti

Maurizio Ragnetti has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7968175
    Abstract: The invention relates to a radiation-curable printing medium based on a thermoplastic polymer and at least one radiation-curable monomeric compound. By means of a compound which comprises a heterocyclic ring, it is possible to achieve a favorable combination of properties comprising reactivity and flexibility of the decoration. Preferred monomeric compounds contain a 1,3-dioxolane or 1,3- or 1,4-dioxane ring, and an acrylic or methacrylic group is attached in the manner of an ester around a methylol group. The invention also provides transfers containing the printing medium and decorative preparations.

  • Patent number: 7674502
    Abstract: The invention relates to a radiation-curable precious-metal preparation, in particular a bright-gold preparation, that contains—in addition to a gold compound, which in particular is soluble in the printing medium, and further customary organometallic compounds—a radiation-curable, in particular UV-curable, printing medium, the polymerisation being initiated by the UV radiation and proceeding in accordance with a cationic mechanism which may optionally be assisted by y process that takes place simultaneously in accordance with a radical mechanism. The invention also relates to a transfer picture containing the precious-metal preparation, and to a process for decorating substrates that are suitable for decoration firing by direct application/printing and indirect printing (decalcomania).

  • Patent number: 6357868
    Abstract: The invention relates to a method of decorating hard materials, especially materials which can be fired for the purpose of decoration, by means of direct or indirect printing. Printing is carried out by means of inkjet technology. According to the invention, a colour paste containing at least 30 wt. % inorganic solids, such as pigments and glass frits, and a thermoplastic medium having a melting point of at least 30° C. is applied to the surface to be decorated by means of a heatable inkjet print head, which preferably additionally has a device for circulating the molten colour paste.

  • Patent number: 5494488
    Abstract: A detergent composition with improved dirt-suspending power, method for its production and use of a suitable polycarboxylate for this purpose. The novel detergent contains, in addition to the customary components such as surfactant, calcium-binding silicate, etc., at least 1% by weight of a polycarboxylate with the schematic structure (X, Y, Z) in which X stands for ##STR1## Y for ##STR2## and Z for--(F).sub.q --.These carboxylates can be produced from acrolein and optionally one or several comonomers by means of oxidizing radical donors without saponifying conditions and/or without subsequent Cannizzaro reaction. The novel detergents exhibits improvements over traditionally used co-builders in all essential detergent qualities. The carboxylates may be used in detergents, fine-fabric detergents, color detergents, liquid detergents and compact detergents.
