EXTRUDED PHOTOCHROMIC FILM ON GLASS
BACKGROUND OF THE INVENTION
The present invention relates to transparent or semi-transparent laminates having a photochromic feature. More specifically, the present invention relates to transparent or semi-transparent laminates of glass and a resin film comprising a photochromic moiety.
Tinted glass is often useful in the automotive, building and other industries. Tinting of optical lenses is also useful and, in some cases, it is known to tint optical lenses with a photochromic moiety to provide a lens which changes tint in response to sunlight or uv light. While it is common to tint glass to provide some protection against bright sunlight and/or uv light, it is not well known to provide large scale photochromic glass. This may be due to the relatively high cost of photochromic moieties or other processing problems or perhaps to the longevity expected of photochromic moieties in use. However, whatever the reason, it would be useful and beneficial if a photochromic glass could be provided which was both effective and economical.
The present invention relates to a method and product by which glass is coated with a resin film having a photochromic feature. Alternatively, glass may be coated with a resin film which is bonded thereto by an adhesive having a photochromic moiety therein to impart a photochromic nature to the laminate. Athough tinted glass has become popular and is well known throughout the world, it would be highly desirable for some uses to have tinted glass which changes tint in response to the amount of sunlight or uv light exposure. Glass windows or panes often suffer from the disadvantage that the windows are consistently tinted during both day and night. Tinted windows may interfere with visibility during hours of darkness.

Photochrornic tinting offers one method for providing tinting in bright sunshine but not in the dark. However, photochromic tinting encounters some of its own problems. One problem is that the life of photochromic moeities is relatively short and may not be suited for uses which require relatively long life cycles. Another problem is that the photochromic moieties must be provided in a matrix which is suitable for the intended end use. For example, in some cases a tint may be required to have a fast change of state and in other cases a slow change of state maybe acceptable. In most cases, however, it would be desirable to have a photochromic moiety which is carried in a matrix which facilitates relatively long life for the moiety.
Further understanding of the present invention will be had from the following specification taken in conjunction with the accompanying drawings.
SUMMARY OF THE INVENTION
A preferred embodiment of the invention is a laminate having a glass layer with an optically clear film, preferably a removable optically clear film, adhesively laminated thereon with at least one of the film and the adhesive comprising a photochromic moiety.. Optionally, the glass may comprise a uv absorber or antioxidant. Preferably, the optically clear film is selected from the group consisting of polyethylene terephthalate (PET), polyurethane, and polyethylene.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
„
P c 'T,/ us «1 fa / 3 ,i. /
Now referring to Figure 1, a preferred laminate of the present invention is illustrated and indicated generally by the numeral 10. Laminate 10 has glass layer 12 and an adhesive layer 14 securing optically clear resin layer 16 thereon. It is contemplated that at least one of adhesive layer 14 and resin layer 16 will comprise an effective amount of a photochromic moiety and that the resin of resin layer 16 will be selected from the group consisting of optically clear PET, optically clear polyurethane and optically clear polyethylene resins.
Suitable glass for use in the present invention include all varieties of glass so long as the glass is suitable for its intended end use. Automotive glasses are especially contemplated for use herein.
Suitable adhesives for use herein are those which are effective to bond the selected optically clear resin layer to the glass layer. It is preferred for many uses that the optically clear resin layer be removable and, a preferred class of adhesives for use herein are pressure sensitive adhesives such as acResin A 258 UV which is a pressure sensitive adhesive commercially available from Bayer plastics.
Suitable optically clear resins for use herein are optically clear resins wherein the primary polymer in the resin is PET, polyurethane or polyethylene. An example of a suitable optically clear polyurethane is Bayer Texin 285 thermoplastic elastomer. An example of a suitable optically clear PET is Lumirror PET from Toray Plastic.
Suitable photochromic moieties are well-known in the art and include those selected from the group consisting of anthraquinones, naphtopyrans, phhalocyanines, spiro-oxazines, chromenes, pyrans including spiro-pyrans and fulgides. Suitable photochromic molecules include but are not limited to those disclosed in United States Patents Nos. 5,882,556 March 16, 1999 to Perrott et al. which is specifically incorporated by reference herein. Reversacl photochromic dyes commercially available from James
,,,, „ ,. , p WO 2008/020 π p, y
Robinson are particularly suitable for use herein. In addition to photochromic molecules, the photochromic composition may include a non-photochromic dye if it is desired to provide a tint to the lens even when the photochromic molecules are not activated.
It has been found that a limited amount of ultraviolet (uv) absorbers, light stabilizers, antioxidants, and or free radical inhibitors may also be included in either the optically clear resin layer or adhesive layer. The use of uv absorbers should be limited to some extent because they tend to have a detrimental effect on the life of the photochromic moiety. On the other hand, free radical inhibitors have a beneficial effect on the life of the photochromic moiety.
Examples of hindered amine light stabilizers or HALS include Sanduvor 3051, 3052, 3055, 3056 from Sandσz/Clariant, Tinuvin 770, 765, 144, 622 from Ciba Geigy, Cyasorb 3346 from American Cyanamid. Examples of antioxidants include Irganox 3114 from Ciba Geigy.
Suitable uv absorbers work by absorbing ultraviolet radiation and converting the radiation into thermal energy through tautomerism. Of course, the selected uv absorber must not substantially absorb the range of uv light required to activate the photochromic moiety. Examples of suitable uv absorbers include Cyasorb W-9 and UV 531, Cyaguard UV 1164 and 1084 from American Cyanamid, Sanduvor VSU from Sandoz/Clariant, Uvinul 3035 from BASF, Tinuvin 328 and P and Irgastab 2002 from Ciba Geigy, Rylex NBC from Dupont, UV Chek AM 101, 105, 126, and 205 from Ferro Corp and Carstab 700 from Morton International.
. Now referring to Figure 2, a preferred method of the present invention is shown and indicated generally by the numeral 20. As illustrated in Figure 2, a converyor belt 22 travels in the direction indicated by numeral 24, conveying glass sheet 26 first underneath extruder 28. Extruder 28 extrudes pressure sensitive adhesive 30 onto the upper surface of glass sheet 26 to form a layer 32 of pressure sensitive adhesive thereon. Then, rolls 34
P π T / IΛ π R and 36 feed and press resin film 38 onto adhesive layer 32 and effect a bonding of film 38 to glass sheet 26. Of course it is contemplated that glass sheet 26, adhesive 30 and film 38 are as described herein.
Further understanding of the present invention will be had from the following examples.
Example 1
Bayer Texin 285 TPU pellets are coated with mineral oil at 15 drops mineral oil per 1000 grams TPU by tumbling. Then 0.30Og (per lOOOg TPU) of Rush Yellow photochromic moiety from Keystone Aniline and 0.20Og (per lOOOg TPU) of Irganox 1035 are tumbled into the TPU. The mixture is then dried at 100 QC for 2 hours.
The mixture is then extruded by a conventional extruder into 0.005 inch thick sheet stock. The sheet is then coated with an acrylic pressure sensitive adhesive and applied to a sheet of glass to form a laminate.
When the laminate is exposed to uv light the sheet turns a bright yellow color and returns to clear when it is removed from the uv light.
Example 2
A 0.002 inch thick sheet of optically clear PET (Lumirror PET from Toray Plastic is coated with a mixture of lOOg of QS 1162 polyurethane adhesive from Mace Company mixed with 0.01 Og of Keystone Anilane Oxford Blue photochromic dye and 0.01 Og of Tinuvin 770 HALS. Then the PET sheet is bonded to a piece of tempered glass and run through a pinch roller to remove all air bubbles to form a laminate.
The laminate is then exposed to uv light which causes it to turn a blue color while under the uv light. When removed from the uv light the photochromic dye fade rate is noted as being exceptionally rapid.
