A patterned light and heat reflective product comprising a substrate with a discontinuous pattern of light and heat reflective coating is disclosed, along with a method for its production, comprising the steps of applying a pattern of resist material to a substrate surface, depositing a continuous light and heat reflective coating over the resist pattern, removing the resist material and thereby also removing the portion of light and heat reflective material overlying the resist material to produce a light and heat reflective coating in a pattern complementary to the pattern of resist material.

Reflective patterned glass product and coating method

An electrically heatable windshield with a hidden bus bar configuration. A border of opaque ceramic material, preferably a lead borosilicate enamel, is bonded to an interior surface of the transparency about its periphery. Opposing electroconductive bus bars, preferably a low frit content silver-containing ceramic material, are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars. An electro-conductive coating is applied to the transparency to interconnect the bus bars and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.

Electrically heatable transparency

A patterned light and heat reflective product comprising a substrate with a discontinuous pattern coating in combination with a light and heat reflective coating is disclosed, along with a method for its production.

A patterned product having a three-dimensional appearance comprising a transparent substrate with a discontinuous pattern coating in combination with a second pattern coating on a separate surface is disclosed, along with a method for its production.

Glass panels with 3-dimensional appearance

A heated transparency is provided with first and second bus bars along opposing edges of a transparency interconnected by an electroconductive coating. The bus bars and coating are applied to the same surface of the transparency. Electrical leads are spaced from the coated surface and are electrically insulated from the coating and bus bars.
