AMINOPLAST RESIN PHOTOCHROMIC COATING
COMPOSITION AND PHOTOCHROMIC ARTICLES
This application claims priority to provisional
Application Serial No. 60/112,794, filed December 18, 1998.
The present invention relates to coatings comprising an aminoplast resin, component (s) having hydroxyl functional groups and photochromic substance (s), hereinafter referred to as photochromic aminoplast resin coatings. In particular, this invention relates to articles coated with such photochromic coatings and photochromic articles, i.e., polymerizates, made from such polymerizable compositions.
More particularly, this invention relates to certain photochromic aminoplast resin coatings which when present on a substrate and exposed to activating light radiation exhibit improved photochromic properties. Further, this invention relates to photochromic aminoplast resin coatings that meet commercially acceptable “cosmetic” standards for optical coatings applied to optical elements, e.g., lenses.
Photochromic compounds exhibit a reversible change in color when exposed to light radiation involving ultraviolet 25> rays, such as the ultraviolet radiation in sunlight or the light of a mercury lamp. Various classes of photochromic compounds have been synthesized and suggested for use in applications in which a sunlight-induced reversible color change or darkening is desired. The most widely described classes of photochromic compounds are oxazines, pyrans and fulgides.
The use of melamine resins as a potential matrix for photochromic compounds in multilayered articles has been disclosed in U.S. Patent 4,756,973 and Japanese patent applications 62-226134, 3-2864 and 3-35236. In U.S. Patent 4,756,873 and JP 62-226134, melamine resin is referred to in a list of different materials, but specific examples of melamines and reactants to produce photochromic coatings are not disclosed. JP 3-2864 and 3-35236 disclose examples of melamine photochromic coatings, but information necessary to duplicate the examples is not included in the applications.
JP 61-268788 discloses a photochromic coating composition consisting of spironaphthoxazine, polyol condensed melamine and a polymer or copolymer of a vinyl compound containing a hydroxyl group. Comparative Examples 6-10 herein represent the examples of JP 61-268788. Lenses prepared with the coatings of Comparative Examples 6-10 demonstrate cosmetic defects and/or have performance properties outside of the desired range. The photochromic aminoplast coatings prepared with the Examplés of the present invention were prepared by mixing all of the ingredients together instead of using the additional step of JP 61-268788, which is to condense a polyol with the melamine resin prior to adding the other ingredients.
It has now been discovered that photochromic aminoplast resin coatings that demonstrate good photochromic properties, i.e., color and fade at acceptable rates and achieve a sufficiently dark colored state, and that meet optical coating “cosmetic” standards may be produced. Such coatings enable the production of photochromic articles using
Plastics in which photochromic compounds do not function properly, and avoids the use of therma. transfer processes.
The novel coatings described herein exhibit a
Fischer microhardness of from at least 45 to 180 Newtons per mm’. Articles of the Present invention having this range of hardness are suitable tor manipulation by automated process equipment without being damaged. The photochromic aminoplast coating composition used to form the rrotochromic coating may
-f ‘WO 00/36048 PCT/US99/30105 . » also be used to form a photochromic aminoplast resin polymerizate.
In recent years, photochromic articles, particularly photochromic plastic materials for optical applications, have been the subject of considerable attention. In particular, photochromic ophthalmic plastic lenses have been investigated because of the weight advantage they offer, vis-a-vis, glass lenses. Moreover, photochromic transparencies for vehicles, such as cars and airplanes, have been of interest because of the potential safety features that such transparencies offer.
Photochromic articles that are most useful are those in which } the photochromic compounds associated with the article exhibit : 15 a high activated intensity and acceptable coloration and fade : ’ rates. ’
The use of photochromic coatings enables the ] ’ preparation of photochromic plastic articles without the need . to incorporate the photochromic compound(s) into the plastic substrate. This is advantageous when the plastic, e.g., thermoplastic polycarbonate, does not have enough internal free volume or polymer chain flexibility for the photochromic compounds incorporated into the plastic to function properly.
Further, use of photochromic coatings result in more efficient utilization of photochromic compounds. The losses associated with more conventional transfer methods, e.g., imbibition or permeation, are avoided as well as the costs assoclated with the disposal of spent photochromic dye solutions.
Other than in the operating examples, or where otherwise indicated, all values, such as those expressing wavelengths, quantities of ingredients, ranges or reaction conditions, used in this description and the accompanying
- 4 - . A claims are to be understood as modified in all instances by the term “about”.
When the coating compositions of the present invention are applied as a coating and cured, the coating exhibits a Fischer microhardness of at least of 45 Newtons per mm’, preferably at least 55, more preferably at least 60
Newtons per mm’. Typically, the cured coating exhibits a
Fischer microhardness of not more than 180 Newtons per mm2, preferably not more than 160 and more preferably not more than 150 Newtons per mm2. The Fischer microhardness of the coating may range between any combination of these values, inclusive of the recited range.
The photochromic properties of the cured coating of the present invention are characterized by a AOD after 30 seconds of at least 0.15, preferably at least 0.16 and most : preferably at least 0.17, and a AOD after 8 minutes of at least 0.47, preferably 0.50, and most preferably at least ’ 0.55. The photochromic properties also are characterized by a bleach rate of not more than 180 seconds, preferably not more than 140, and more preferably not more than 100 seconds - all as measured at 85°F (29.4°C), and as described in Part D of
Example 1é¢ herein.
Amrinoplast resin coatings having microhardness and photochromic performance properties within the aforestated ranges can be produced by balancing the amounts of the components of the crosslinkable composition used to prepare the coating matrix. For example, the specific properties of the components comprising the coating matrix or polymerizate that will effect the micrshardness and photochromic performance properties of the aminoplast resin matrix are the glass transition temperature and molecu.ar weight of the components, and the crosslink density of the resultant matrix.
[8 - EE
Generally, using components having higher glass transition temperatures and molecular weights results in coatings and polymerizates having an increased microhardness and vice versa. An increase in the number of reactive groups of a 5S component will also cause an increase in the microhardness, provided that all of the groups are reacted. In the latter case, the increase in the number of reactive groups, i.e., crosslinking sites, increases the density of the cured coating. It is believed however that the harder the coating or polymerizate the slower the performance of the photochromic compound contained therein.
The contribution of a particular component, e.g., a hydroxyl-functional component such as an organic polyol, to either the hardness or softness of the coating can be readily determined by measuring the Fischer microhardness of the : resulting aminoplast resin coating. The hardness-producing component, as defined herein, is a component that increases the microhardness of the aminoplast resin coating as its concentration increases. Similarly, the softness-producing component, as defined herein, is a component that decreases the microhardness of the aminoplast resin coating as its concentration increases. Examples of hardness-producing organic polyols include, but are not limited to, low molecular weight polyols, amide-containing polyols, polyhydric polyvinyl alcohols, e.g., poly (vinylphenol), epoxy polyols and polyacrylic polyols. Softness-producing organic polyols include, but are not limited to, polyester polyols, urethane polyols, and polyether polyols, e.g., polyoxyalkylenes and poly (oxytetramethylene)diols. All of the aforementioned polyols are defined hereinafter.
The photochromic coating composition of the present invention may be prepared by combining a photochromic component with the reaction product of hydroxyl-functional i component (s) having at least two functional groups and an aminoplast resin, i.e., crosslinking agent. The coating composition may further include catalyst.
Solvents may also be present in the coating composition. However, as described herein, solvents are not factored into the weight ratios and weight percents stated herein. All weight ratios and weight percents used herein are based on the total solids in the coating composition, unless stated otherwise.
Typically, the component having a plurality of hydroxyl groups of the present invention is a film forming polymer, but a component which is not a film forming polymer may be utilized. However, it is necessary that at least the combination of the aminoplast resin component with the component having a plurality of hydroxyl groups results in a crosslinked polymeric coating.
The functional group containing component (s), hereinafter referred to as the functional component, has at least two pendant and/or terminal hydroxyl groups. The component having such functional groups may be a monomer, polymer, oligomer, or mixture thereof. Preferably, the component is a polymer or oligomer such as an acrylic polymer, a polyester polymer or oligomer, or a blend of two or more of these materials. Acrylic polymers or cliigomers are preferred materials.
The acrylic materials of the functional component are copolymers of one or more alkyl esters of acrylic acid or methacry:ic acid and hydroxyl functiocna. ccmponents, and, optionally, one or more other polymerizable ethylenically unsaturated monomers.

A further description of selected ethylenically unsaturated monomers is included - hereinafter in relation to the preparation of polyacrylic polyols.

Pre-cleaning with an alcohol-based cleaner or organic solvent prior to washing may be required to remove adhesives from labels or tapes.
In some cases, it may be necessary to apply a primer to the surface of the substrate before application of the coating composition of the present invention.

Industries, Inc., respectively. In addition, depending on the intended use of the coated article, it may be necessary to apply an appropriate protective coating(s), i.e., an abrasion resistant coating onto the exposed surface of the coating composition to prevent scratches from the effects of friction and abrasion. In some cases, the primer and protective coatings are interchangeable, i.e., the same coating may be used as the primer and the protective coating(s). Other coatings or surface treatments, e.g., a tintable coating, antireflective surface, etc., may also be applied to the cured coating of the present invention.

Polymerization of the coating composition may be accomplished by adding to the polymerizable composition a catalyst and curing in a manner appropriate for the specific composition and desired shape. The resulting polymerizate demonstrates the same Fischer microhardness and photochromic performance properties of the cured coating, is substantially free of cosmetic defects and may have a thickness of 0.5 millimeters or more.
In one contemplated embodiment, a glass two-part lens mold is filled with desolvated photochromic coating composition, i.e., the polymerizable composition containing a minimal amount of solvent, which may additionally contain a catalytic amount of phosphoric acid. The glass mold is sealed and placed in an oven. A thermal polymerization cycle is initiated which may range from 10 to 20 hours duration at about 45 to 110°C. Afterwards, the mold is opened and the
¢ 1 resulting lens, i.e., polymerizate, is removed. The polymer lens thus produced is then annealed for a period and at a temperature sufficient to eliminate residual stresses in the lens. The temperature is generally between 100 and 110°C and annealing is carried out for 1 to 5 hours. If the photochromic material was not included in the polymerizable composition, it may be incorporated into the polymerizate by imbibition, permeation or other transfer methods known to those skilled in the art.
In a further contemplated embodiment, a semi- finished single vision (SFSV) lens having an adherent layer of the photochromic crosslinkable composition of the present invention may be prepared by an overmolding process.
Typically, a predetermined volume of the photochromic polymerizable composition is dispensed into a volume defined by a spherical negative glass mold, which approximately matches the front surface curve and the outer diameter of a
SFSV lens. The glass mold is fitted with a circular polyvinyl ’ chloride gasket that extends approximately 0.2 millimeters above the mold and has an inside diameter approximately 4 millimeters less than outside diameter of the glass mold.
After the monomer is dispensed, the SFSV lens is carefully placed on the dispensed polymerizable composition which spreads to fill the defined volume. A circular glass plate having an outside diameter equal to or greater than that of the lens is placed onto the rear surface of the lens. A spring clamp is positioned so that one side of the clamp is on the front surface of the negative mold and other side of the clamp is on the back surface of the glass plate. The resulting assembly is sealed by taping the circumference of the plate-lens-gasket-mold using polyurethane tape. The assembly is preheated in an air oven from 3C to 95°C tor 60 minutes and subsequently, the temperature is increased trom
