Abstract
A graphic glass laminate is created by heat-laminating a printed sheet of extruded polyurethane between two plates of glass, using normal autoclave process. The polyurethane interlayer bonds directly to the glass with very little distortion to the color or registration of the printed ink.
The resulting composite is extremely strong and safe, having better structural and superior heat-resistant characteristics compared to regular safety glass and may contain an extremely artistic and decorative look. The interlayer graphics can be made "light-fast" when proper inks are used. Transparent and translucent inks may be employed and the glass may be used with different lighting techniques, such as edge-lighting.

It is known to replaaa thc~ polyvinyl butyral interlayeac with a composition of polyurethane as taught in U.S. Patent 3,509,015. In this instance, the polyurethane int~rlayer is cast in place from a pourable resin. Decorative affects may be obtained by CoxArix~~J the resin prir~r to lamination.

butyral materials. zn addition, only s~mald, areas where the graphic covers tha glass are possible, the coloring materials are not lightTfast and a very high failure rate usually occurs. Where the znatexials are not molecularly fused (heat laminated), the compos~,te is often not permanent.
rya one before has been a'bJ.e to achieve mass production printing on a transparent interlayar fused bx heat lamination between sheets of glass to yi~:~.d ~ unitary, permanent, graphic panel.
~~~ ~ ~ ~~vPZaT~o~
To overCOm~: the problems in the prior art described above, a decorative laminated glass has been devised from the composition and method as follows. It has been found that mass production printing processes, such as automated silk screening, can be used to apply non-solvent-based inks directly on sheet polyurethane. Sheet polyurethane is extremely easy to handle and will accept a wide variety of inks. Because of this ease of handling, printing of inks on the polyurethane interlayer can be separated from the laminating process, both in time and distance. The printed polyurethane sheets can easily be rolled up for storage or shipment to the glass production site. These factors make the instant process both convenient and inexpensive, since handling and transporting the glass components is kept to a minimum.
The printed polyurethane interlayer is then heat-laminated between two pieces of glass using standard autoclave laminating procedures without the use of adhesives. The polyurethane interlayer bonds directly to the glass with very little distortion to the color or registration of the printed ink. The resulting composite is extremely strong and safe, having better structural and superior heat resistance characteristics compared to polyvinyl butyral safety glass, and may also contain an extremely artistic and decorative look.
Furthermore, the interlayer graphics can be made "light-fast"
when proper inks are used. Transparent and translucent inks may be employed so that the glass may be used with different lighting techniques, such as edge-lighting. The results are both permanent, inexpensive, and visually unique.
Thus the invention provides an architectural glass laminate, comprising:
a. two sheets of rigid, transparent material, b. an interlayer sheet of extruded polyurethane, heat-laminated between said sheets of rigid material, and c. non-solvent based ink containing solid pigments printed on said polyurethane interlayer, prior to lamination, to provide a permanent graphic panel of unitary construction.
The invention further provides a method of manufacturing an architectural glass graphic panel, comprising the steps of:
a. printing a graphic onto a flexible sheet of extruded polyurethane using non-solvent based inks containing solid pigments, and b. heat-laminating said polyurethane between two sheets of glass using autoclave laminating procedures without the use of adhesives.
It is important that the ink or paint be chemically compatible and self-adhesive to the urethane sheet material.
It may be applied by brushing, spraying or printing to the extruded urethane interlayer. The paint or ink film may be 3a ~~~~J~ ~~~~
dried by air, or ;force-dried by ultraviolet light using light-GUrsd ink. The urethane interlayer may 1~e placed between glass or polycarbonate, or a combination of both.
,~ variety of uses are possible gor th3.s new graphic glass. Far instance, one color mar be applied to create a graphic effect to resemble sandblasting or etching. Also, by using a faux-color praaess, a photographic effect can be aahieved that can be vi~:wed from either side of the g~,ass.
Finally, the polyurethane interlayer can be used in combination with photosensitive ar e7,ectrically-~conduativs materials, inks, or resins.
in yet another embodiment, a light-reacting material, such as phosphorous, interference pigments or any light-reacting material, can be ground or blended in a t~°ax~sparent workable vehicle that is applied to the urethane sheet. In this embodiment, the laminate would appear transparent; but, when exposed to various lights by either edge-lighting or planing a light at certain angles, it would react to the material and .a graphic image would appear on the interlayer substrate. Other adaptations and modifications will be readily apparent to those of ordinary skill in the art from th~ following drawings and desoription of the preferred embodiment.

The production of 'the present invention is a simple, two-step process. First, graphics are applied tp sheet urethane by directly printing thexeon using mass producta,on techniques, such as siikscreening, and then the urethane is bonded to the g~.ass plates through the standard glass-laminatiz~c~ autaciave prooess, The surprising discovery of this invention is that the printed substrate maintains its quality and registrat~.on throughout the a~xtoC~,ave process and does not ,inhibit the quality o~ the lamination between the urethane and the glass. vax~.ous inks can be used but must be ton-solvent-based ~so that there is no chemiCaJ, reaction with the urethane. polymer inks and polyvinyls that adhere to urethane are possible choices. Also, 'eso~.id inks~o, such as ~UV-drying inks and various other inks that do rat use salv~tnts such as THF ax ~MF keytonesr should also work well.
An important charaateristio o~ the ink is that it adheres well to the urethane without reacting to it. 2t is also necessary that the ink be vary glexibJ.e la that it will not crank when the sheet ur~thane is wound ~.nto a roll Eor storage or trar~spartati.on. Also, the film thickness of the ink should be kept to a mfn~.mum so there is a seepage effect of the urethane thxough the ink during the laminating process. Thig is a key facto~c and par~n~.ts molecular bonding _~_ ~~~f.°'y ryy];

,etween the ink, urethane and the glass. It has be~:n found that using this process, the urethane sheet and ~.nk combination adhere directly to the glass without distortion or loss of quality of the printed g~;aplaic.
As explained above, sheet urethane is extremely easy to ~,andle and laminates well with g~,ass, even when used in very large a~ceas. Contrary to the laminating process using PVC, which requires large or heavy machinery and expensive die-cutting materials, the present process does not have to be maintained in a temperature and humid3.ty~GOntxolled environment. this ease of handling permits large pieces of graphic glass try be manufactured very inea~pensively.
Printing may bc~ applied to the sheet urethane with standard s~.lks~creen process and th~ urethane ;may be fed into the printing presses in tall form ox in cut sheets.
r.Che printing may be to apply lettering or othex° graphics ;for various effects. For instance, a single off-white color can be applied to create the graphic effeot o~ sandblasting or etching. A four-color process using standard four-color inks (yellow, magenta, cyan and black) can be used to create any tones ox shades of color'. Furthex~~nore, by using transparent inks, one is able to create di~~~:rent hue effects by printing one ink cover another. In yet a~aother embodiment cantemplated by this invention, the ink may include materia7.s such as phosphorus, interference pigments or any yight~-reacting material that oan be ground and blended into a tr~nspaxent, workable material that can be printed or applied to the urethane. This last embs~diment may be used in combination with various lighting teahni~ues, such as edgew lighting.
