The phosphoric acid ester includes at least one of a phosphoric acid diester and a phosphoric acid monoester. R1 is a phenyl group or a phenyl group in which at least one hydrogen atom is substituted by a halogen atom. When molar contents of the phosphonic acid, the copper ion, and the phosphoric acid ester are respectively defined as CA mol, CC mol, and CE mol and a total molar content of reactive hydroxy groups is defined as CH mol, the relations CA/CE<1 and CH/CC>1.95 are satisfied.

Abstract: An apparatus for digital printing on articles (2), comprises a drum (3) rotatable about a central axis (C), carrying piece-holder elements (4) circumferentially distributed around said central axis (C) and each configured for carrying an article (2) being processed. The drum (3) rotates to transfer the piece-holder element (4) through printing stations (9) carrying printheads (10), each operating according to a printing area (15) of predetermined length (L), to create a printing pattern (M) on a side surface (2a) of each article (2), driven in rotation around its own axis (X). Auxiliary movement devices (21) shift the printhead (10) parallel to the main extension direction (D) of the printing area to allow the articles to be processed having an extension greater than the length of the printing area (15). It is also described a printing process implemented by the apparatus.

Abstract: Articles each having a reference mark located around a respective extension axis, are loaded on piece-holder assemblies distributed around a central axis of a rotatable drum, and each including a pair of spindles operable in rotation by a same motor, each around a respective longitudinal axis. The drum rotates about said central axis to transfer said piece-holder assembly to a printing station, where a printing pattern is formed on a side surface of each article driven in rotation by the respective spindle. Before transferring to the printing station, at least one of the articles is oriented around the respective spindle, to place the reference marks of the articles along a same angular orientation around the respective extension axes.

Abstract: An apparatus (1) for the surface treatment of objects (2), comprising a drum (3) having a peripheral zone (3b); a plurality of gripping elements (4) disposed in the peripheral zone (3b) of the drum (3) and configured to each receive a respective object (2) to be treated; printing means (5) associated with the drum (3) and comprising at least one print head (6), the head (6) being positionable in front of the gripping elements (4) in order to print on an object (2); the printing means (5) are configured to print on a lateral surface (2a) and on a base surface (2b) of the caps (2) on the same drum (3).

Abstract: The invention relates to a translucent or transparent, colored enamel that contains metal nanoparticles that lost their natural tendency to aggregate with each other, and having a color essentially provided by the reflection of light. The nanoparticles have lost their natural capability to aggregate with each other due to the application of a coating, or because they have been functionalised electrostatically or using highly sterically hindered entities or using hydrophilic entities located at the surface thereof. The nanoparticles may be gold nanoparticles that impart an intense and deep red to said enamel.

Abstract: A ceramic enamel composition consists of an oxide frit, a bismuth silicate seed material, a pigment, and a vehicle. A preferred bismuth silicate seed material is selected from crystalline Bi.sub.12 SiO.sub.20, Bi.sub.4 (SiO.sub.4).sub.3, and Bi.sub.2 SiO.sub.5, and mixtures thereof. Upon firing a glass substrate coated with the enamel, components of the enamel adhere to the substrate. The glass can be formed with a die to a desired shape with reduced sticking of the coated region to the die. The ceramic enamel is particularly useful in providing a colored border around automotive glass, which enhances appearance and reduces degradation of adhesives by ultraviolet radiation.
