Disclosed are composite transparencies and methods for their production. The colored composite transparencies include a surface at least partially coated with a transparent tinted coating deposited from a coating composition comprising polymer-enclosed color-imparting particles.

Composite transparencies

A low temperature solder including indium in the range of 62-65 weight percent and tin in the range of 31-33 weight percent uses the heat generated during thermal treatment of one or more glass sheets to melt the solder. In one non-limiting embodiment, a lead providing external access to an electrical conductive arrangement, e.g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e.g. a lead soldered to each of the bus bars during thermal processing of the sheets, e.g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks.

Solder compositions; method of soldering, and a laminated transparency having bus bars

The invention relates to using the heat generated during thermal treatment of one or more glass sheets to melt solder. In one nonlimiting embodiment, a lead providing external access to an electrical conductive arrangement, e.g. a conductive member between and connected to spaced bus bars between laminated sheets has an end portion of a connector, e.g. a lead soldered to each of the bus bars during thermal processing of the sheets, e.g. during the lamination of the sheets during a windshield manufacturing process. In another nonlimiting embodiment, the connector is soldered to the electrically conductive arrangement during the annealing of glass blanks following the heating and shaping of the glass blanks. Soldering the leads during the annealing or laminating process eliminated possible thermal damage to the sheet by having the sheet heated during the soldering operation instead of only a small surface portion of the sheet at and eliminates the cost of a separated soldering operation.

Method of soldering and solder compositions

The present invention provides a transparent antenna including a transparent dielectric substrate, an electroconductive antenna element positioned along a major surface of the substrate, an electroconductive patch capacitively or directly connected to the antenna element, and a connector secured to the patch to permit transfer of signals generated by the antenna element to an electromagnetic energy transmitting and/or receiving device. The patch, is configured to have a visibility coefficient (i.e. a ratio of the non-opaque area to the total area) between 0 and 1. In one particular embodiment of the invention, the antenna element includes one or more transparent, electroconductive coatings positioned between first and second glass plies of a windshield for a motor vehicle and the electroconductive patch is applied to an exposed major surface of the windshield such that it overlays at least a portion of the antenna element and is capacitively coupled to the antenna element. The patch is may be formed from an opaque electroconductive ceramic IR, UV, thermoplastic or thermoset paint.

Antenna on-glass

The present invention provides for the use of electroconductive ceramic thermoplastic, thermoset and ultraviolet radiation curable paints as antenna elements and/or connector elements in a transparent antenna system. Antenna elements are formed on a major surface of a rigid transparent ply, preferably glass, and connected to a connector that permits transfer of signals generated by the antenna element to an electromagnetic energy transmitting and/or receiving device. The connector may be in direct electrical contact with or capacitively coupled to the antenna element. If desired, additional rigid transparent plies may be secured to the first ply to form a laminate, wherein the antenna element or the antenna element and the connector are laminated between the rigid plies.
