Description

DETAILED DESCRIPTION OF THE INVENTION (Summary of the Invention) An organic polymer plastic base material for an optical component is provided with a conductive layer on at least one surface of the plastic base material and coated with an abrasion resistant layer to provide a non-electrical It becomes durable and wear resistant. A novel non-electrical, non-reflective optical component is obtained by coating at least one side of an organic polymeric plastic substrate with a protective organosilica coating composition and subjecting the coated plastic substrate to a glow discharge treatment. Created by.

FIELD OF INDUSTRIAL APPLICATION The present invention relates to a novel non-electrical, abrasion-resistant optical component, in particular a plastic ophthalmic lens, having a conductive layer deposited on at least one surface, and in addition:
It also has a tight abrasion resistant coating. The invention also relates to a new and improved method of manufacturing such optical components.

The present invention also details a method of coating an optical surface. A novel and useful method for coating ophthalmic lenses, particularly where the finished lens has a non-electrical, non-reflective surface, is also detailed.

(Conventional technology) Static electricity is a general term for phenomena caused by the accumulation of electric charges.

Attraction of particles by electrically charged objects is caused by static electricity. When approached by other insulators (dirt, dust, etc.), the negatively charged object repels the electrons on the particle surface.

In this way, the surface of the particle becomes positively charged and an attractive force is induced. In other words, as the insulator (dirt, dust) approaches, the charge on the charged substance gradually becomes electrically neutral and eventually becomes negatively charged, repelling the electrons on the surface of the particle. Electrically charged objects made of plastic substrates, especially plastic ophthalmic lenses coated with abrasion-resistant coatings, attract flakes and can be used in many applications (polycarbonate in steel mills, textile mills, coal mines). safety lenses). Upon eye contact, these dust particles cause light scattering and hazing, which limit the wearer's visual acuity and require frequent cleaning.

By the way, some temporary treatments are used commercially for static electricity build-up, but these temporary treatments are short-lived and must be repeated intermittently.

Another method for preventing static electricity accumulation in plastic lenses is to incorporate an antistatic agent into the plastic base material. However, it is known that these antistatic agents are irritating to the eyes and are not suitable for use in the eyes. Furthermore, although these antistatic agents are applied to the surface of the plastic substrate, they end up attacking the surface that comes into contact with the coated substrate. Reducing the reflection of optical surfaces is often required in numerous applications.

By reducing the reflection of light that strikes the surface of the optic, a greater portion of the incident light will be transmitted through the optic.

When optical components are made from polymeric plastic substrates, the reflections are generally reduced by vacuum deposition of a coating layer or layers that are engineered to reduce reflections by interference effects. There is. Creating these layers requires sophisticated technology, and for mass production, complex equipment is required. Also, if some of these two coatings are exposed to moisture or other unsuitable environments, these coatings can quickly fade. If the coating is inadvertently exposed to an unsuitable environment during preparation, the adhesion of the coating to the substrate may be poor and the coating may flake off from the optical component or , will separate.

In recent years, electrical discharges have been frequently used to produce pliable, thin coatings of solid organic materials that are deposited on the surfaces of substrates. The discharge is sustained in the spark, corona and glow regions of electronic phenomena.

Glow discharges are defined as non-sparking, quiet discharges with spatial potential changes near the cathode caused by differences in the level of potential near the cathode that is significantly higher than the ionization potential of the surrounding gas. Glow discharge is caused by potential changes, firstly due to electron liberation and secondly due to the bombardment of positive ions near the cathode. Also, glow discharge has a lower potential than corona discharge,
It has the characteristics of low voltage and high current. Glow discharge occurs after potential energy exceeds its limit and sparks or decomposes, and is an irreversible change that occurs in an electronic circuit.

Therefore, it is a fundamental objective of the present invention to prevent the generation of static electricity in optical components.

It is a further object of the present invention to prevent the generation of static electricity in coated plastic ophthalmic lenses with abrasion resistant coatings.

It is a further object of the present invention to create a non-electrical abrasion resistant optical component that is not sensitive to moisture or wear due to use.

It is another object of the present invention to reduce reflections and prevent static electricity generation on the surface of plastic ophthalmic lenses coated with abrasion resistant coatings.

It is a further object of the present invention to reduce reflections on the surface of an optical component without causing peeling or separation of the coating from the surface of the optical component.

(Problem to be solved by the invention) By providing a conductive layer on at least one surface of the organic polymer plastic base material, or by coating the surface of the conductive layer with a protective layer, it is possible to prevent wear and tear due to moisture and use. The problems of the prior art are overcome by the knowledge that non-sensitive, non-electrical abrasion resistant optical components can be made.

Tin oxide (In5n02), a well-known semi-transparent conductive material in the industry, such as doped indium,
conductive layer, the conductive layer is deposited on at least one side of the plastic substrate and before the abrasion resistant coating is applied to transform it into a sufficiently transparent state. Subject to glow discharge.

In some cases, if such a transparent conductive layer is used, a first coating of silicon oxide is applied to one side of the plastic substrate before the conductive layer is applied, and in other cases. The first coating of silicon oxide is applied either after an optional glow discharge treatment or before the abrasion resistant coating treatment. A novel non-electrical, non-reflective optical component is produced by coating at least one side of an organic polymeric plastic substrate with a protective organosilica composition and subsequently subjecting the plastic substrate to a glow discharge treatment. With the knowledge that
Another problem of the prior art can be overcome.

The ophthalmic lens is an optical component in the present invention, but other optical components included in the present invention include solar panels, appliances, CRT displays, and the like.

Means for Solving the Problems In the present invention, a non-electrical, wear-resistant optical component includes: an organic polymer plastic substrate; at least one surface of the plastic substrate; A conductive layer attached to the conductive layer; a protective layer that coats the surface of the conductive layer.

Any type of organic polymer plastic substrate can be used, such as polycarbonate substrates,
More specifically, poly(2,2'-dihydroxyphenylpropane) carbonate base; allyl base; more specifically, CR-39 (trade name) base; or acrylic base, more specifically polymethylmec. Acrylate substrates can be used. CR-39 (trade name) is polydiethylene glycol bismuth (allyl carbonate) obtained from PPG Industries. If the optical component of the present invention is used for ophthalmic purposes, the plastic base material must be transparent. Must.

The conductive layer may include any metal or semiconductor. The type of metal used for the conductive layer depends on the type of optical component being manufactured.6 For example, gold is very advantageous in any application. Gold emits a soothing green glow and reflects infrared rays, making it an ideal metal for use in architectural glass and temperature control. However, they are expensive and generally do not adhere well. For ophthalmic use, the following conditions are required: maximum light transmission, good adhesion to lenses, and surface coating processing. For example, chrome has good adhesion properties and is advantageous for ophthalmic applications. Other similar metals are nickel, nichrome (nickel chromium alloy), and palladium.If the metal is useful as a conductive layer in ophthalmic components, the metal layer can be used to maximize light transmission. It must be as thin as possible. On the other hand, in order for the metal layer to conduct, the thickness must be sufficient to form a continuous film of -1. In the case of chrome, this optimum thickness has been found to be approximately 30 ± 5 angstroms; when the chrome layer is approximately 30 angstroms thick, the coating becomes conductive and the visible light of the coated lens increases. The light transmittance still satisfies the ANSI condition of 88% required for flat plate safety lenses, or has a value very close to that condition. If the visible light transmittance percentage of the coated plate safety lens of the present invention is at least 85%
If so, it is believed that the advantages of such lenses, the so-called abrasion resistance, outweigh the reduced transmission.

Thicker non-electrical metal coatings with visible light transmission of at least 60% are of considerable utility in other visual and optical applications.

The conductive layer applied to at least one side of the plastic substrate may be applied by any conventional method known as a technique for producing conductive layers of controlled thickness, such as vacuum evaporation or sputtering. can be formed.

FIG. 1 shows an ophthalmic lens (2) with a chrome metal layer (4) deposited on its convex surface. The lens is then surface coated with an abrasion resistant coating (6).

Even if a conductive metal layer is surface-coated with a non-conductive coating, the conduction through the non-conductive film and metal layer will generate more static electricity on the surface than a similar coated lens without an underlying metal coating. It is quite possible to eliminate them at a faster rate.

Table 1 shows the poly(2,2'-dihydroxyphenylpropane) carbonate base material, chrome metal conductive layer,
and an organic silica layer (US Patent No. 421182)
3) shows the properties of the ophthalmic lens.

Table 1 Chrome metal coating Visible light transmittance 76.6% Charge decay time 3.6 seconds Conductive layer material Gr Metal coating thickness
35 angstrom charge decay time is 3.6
This compares to the charge decay time of 10 or 100 minutes for polymer ophthalmic lenses or polymer lenses coated with organosilica under the same conditions without the conductive layer. It is possible to do so.

Because it is difficult to accurately control the thickness of thin metals, translucent semiconductors that can be made transparent, such as indium doped with tin oxide or zinc oxide, are the preferred materials for conductive layers in ophthalmic lenses. be. A suitable form of tin oxide doped indium for use is Patinal Substrate A (trade name) from E,M, Laboratories.

If a semi-transparent conductive material such as tin oxide doped indium known in the industry is used as the conductive layer, vacuum evaporation or sputtering or other techniques for producing a conductive layer of controlled thickness may be used. After the conductive layer has been applied to at least one side of the plastic substrate by another method known as lithography, the plastic substrate is subjected to a glow discharge treatment before the abrasion resistant layer is applied. The purpose of the glow discharge treatment is to transform the semiconductor into a fully transparent state. Although glow discharge treatment can occur when sufficient pressure, voltage, and current are present to sustain glow discharge, it is preferred that the semiconductor be treated in oxygen gas at a pressure of 0.05 to 0.15 tJl. The glow discharge treatment is preferably performed for 1 to 10 seconds, more preferably for 1 to 5 seconds, under a voltage of 100 to 1500 DC (VDG) and a radio wave of 100 to 80 hA. The thickness of the semiconductor layer is not critical; for example, a 100 angstrom thick tin oxide doped indium layer has been found to be suitable. It has been shown that indium doped with 100 angstroms of tin oxide readily converts to the transparent state with a glow discharge of 1 to 5 minutes. These 10
A thickness of 0 angstroms is a tiny optical absorbance (:
Optical density = internal transmission density: If the intensity of the incident light on the substance is I, the intensity of the transmitted light is I, and the absorbance is A, then
A = logIO (Io/I) Lambard-Beer's law)
Sufficiently good conduction can be obtained. It is extremely difficult to make a semiconductor film sufficiently transparent. For example, when using the glow discharge method to convert an indium layer doped with tin oxide, the indium layer
If thicker than 50 angstroms, it is necessary to deposit a glow discharge treated coating with a thickness of 100 angstroms after each increment to obtain the target thickness.

Semitransparent conductive materials that can be converted to transparent, such as an idium layer doped with tin oxide, are useful as conductive layers, such as silicon oxide (SiOx, where X ranges from 1 to 2), Preferably, a first film of (as defined for the purposes of the present invention) is applied before the conductive layer is applied to the side of the plastic substrate on which the conductive layer is applied. Rather, a first coating of another silicon oxide is applied on top of the conductive layer before the abrasion resistant coating is applied and after the glow discharge treatment. The first silicon oxide coating layer is used to facilitate the attachment of a transparent conductive layer, such as an indium layer doped with tin oxide, to the plastic substrate and the abrasion resistant coating. .

Table 2 shows a polycarbonate substrate, an indium conductive layer doped with tin oxide (converted to a fully transparent state by glow discharge treatment), and a coating such as lead powder (for ophthalmic use). This shows the results of the standard fire resistance test (of lenses). The ophthalmic lens has the same composition with the addition of a silicon oxide layer on a polycarbonate substrate and a silicon oxide layer on a fully converted indium layer doped with tin oxide.

This should be compared to the charge decay time of 10 or 100 minutes for polymer ophthalmic lenses or polymer lenses coated with organosilica.

The abrasion resistant layer of the optical component of the present invention comprises an organic layer, for example melamine formaldehyde; an organic silica layer, for example an organosiloxane polymer or a silica-organosiloxane polymer:

An ophthalmic lens was prepared containing a poly(2,2'-dihydroxyphenylpropane) carbonate substrate, a layer of chrome metal vacuum deposited on a plastic substrate, and a coating of standard lead powder or other materials. Tests were conducted to clarify the relationship between non-electrical functions and visible light transmittance. FIG. 2 is a graph showing visible light transmittance versus charge decay time. FIG. 3 is a graph showing the thickness of the designed chrome layer versus the transmittance.

When the visible light transmittance is about 70-89%, the charge decay time is almost the same low value, but when the visible light transmittance is about 88%, the charge decay time is about the same low value.
It can be seen from FIG. 2 that the charge decay time shows a large increase when the charge decay time exceeds %. This increase in decay time is due to the fact that the chrome layer is too thin to form a continuous film and therefore conducts less. What has been described above can be understood from FIG. FIG. 3 shows that there is a clear close relationship between the thickness of the chrome and the visible light transmittance, such that the thinner the chrome layer is, the higher the visible light transmittance.

Another embodiment of the present invention is an optical component molded from an organic polymeric plastic substrate, which comprises a protective organosilica coating composition on at least one side of which has been subjected to a vacuum glow discharge. And it's covered.

Any polymeric plastic substrate can be used, including polycarbonate substrates, especially poly(2,2'
-dihydroxyphenylpropane) carbonate; allyl bases, especially CR-39 (trade name) bases; acrylic bases, especially polymethyl methacrylate-1. CR-39 (trade name) is polydiethylene glycol bismuth (allyl carbonate) obtained from the PPGT Company.

The organosilica coating composition includes, for example, Clark's silica-organosiloxane polymer coating composition or the silica-organosiloxane polymer coating composition disclosed by Suzuki et al. The coating by Suzuki et al. is preferred as the organic silica coating of the present invention. This coating is known not only to be light-colored but also to have excellent adhesion properties even under unsuitable environments; furthermore, the surface of the optical component of the invention is coated with this composition, and then The surface of the optical component becomes non-electrical and non-reflective when subjected to a glow discharge. FIG. 4 shows the reflection of a lens based on CR-39® alone with this coating before and after glow discharge treatment. Line IO describes the reflection of the coated lens before the glow discharge treatment, and line 12 shows the lower reflection of the Suzuki et al. coated lens after the glow discharge treatment. When the surface of the optical component of the present invention is coated with Clark's composition and then subjected to a glow discharge, the optical component does not become anti-reflective, but completely non-electrical.

To describe the details of glow discharge treatment, DC, A
The method of plasma generation was found to be unimportant as all of the C (60 Hz) and RF plasmas proved effective. Gas pressure has also been found to be unimportant as any pressure can maintain a plasma that produces the desired results. Of course, when it is desired to perform glow discharge treatment in the minimum amount of time necessary, there are optimal conditions for pressure and power (current and voltage). For example, it has been found that the time required to create a low reflective surface is determined by the power supplied. For RF glow discharge, 5 minutes was sufficient, while for DC glow discharge, a time of 5 to 15 minutes was required.

One of the factors that makes a difference in glow discharge treatments that result in particularly non-reflective surfaces is the type of gas used. However, oxygen, air, helium, nitrogen, etc. all
Although both Suzuki et al.'s coating and Clark's coating were able to produce non-electrical surfaces, gases containing only oxygen (02, air, and mixtures of 02 and CF4), for example, are non-reflective. This method was effective in producing a glaring surface, and was also effective only in the coating by Suzuki et al.
