JP6862757B2 - Optical resin layer and spectacle lens with resin layer - Google Patents

Description

The present invention relates to an optical resin layer and a spectacle lens with a resin layer.

Lenses such as eyeglasses and sunglasses are made of a light-transmitting material such as a resin material or a glass material (see, for example, Patent Document 1).

Such a lens can be made into a colored lens by containing a coloring material such as a dye, for example. Therefore, the design can be improved.

However, for example, when the lens is red, the wearer sees the entire field of view red, which makes it difficult for the wearer to identify a red object such as a lit red traffic light. Therefore, it is hard to say that such sunglasses are excellent in color distinction.

In this way, when color distinction is emphasized in sunglasses, the color of the lens of the sunglasses is limited. That is, it is difficult to achieve both high color distinctiveness and high designability.

The shape of the frame 2 is not limited to the one shown in the figure as long as it can be attached to the user's head.

A spectacle lens 3 with a resin layer is attached to each rim portion 21. Since each spectacle lens with a resin layer has the same configuration, one of the spectacle lenses with a resin layer 3 will be described below as a representative.

As shown in FIG. 2, the spectacle lens 3 with a resin layer has a spectacle lens 4 having light transmission and an optical resin layer 5 attached to the front surface of the spectacle lens 4.

The spectacle lens 4 has a plate shape that is curved toward the outside. The spectacle lens 4 has a lens function of condensing incident light L incident from the outside.

The constituent material of the spectacle lens 4 is not particularly limited as long as it has light transmittance, and for example, various resins of various thermoplastic resins, thermosetting resins, photocurable resins, and the like. Examples include materials, various glass materials, and various crystals.

The thickness _{T 4} of the spectacle lens 4 is not particularly limited, for example, is preferably about 0.5 to 5.0 mm, more preferably about 1.0 to 3.0 mm. As a result, both relatively high strength and weight reduction can be achieved at the same time.

Next, the optical resin layer 5 will be described.
As shown in FIG. 2, the optical resin layer 5 includes a resin layer 50 with an optical function, a polarizing layer 53, a pair of bonding layers 54a and 54b, a protective layer 55, and a first color material layer (first). A layer) 56a and a second color material layer (second layer) 56b are provided.

Further, in the optical resin layer 5, the bonding layer 54a, the polarizing layer 53, the bonding layer 54b, the resin layer 50 with an optical function, and the protective layer 55 are laminated in this order from the lower side (glass lens 4 side).

The resin layer 50 with an optical function has a resin layer 51. Further, the resin layer 51 may contain a filler.

The constituent material of the resin layer 51 is not particularly limited, but is limited to acrylic resin, methacrylic resin, polycarbonate, polystyrene, cyclic ether resin such as epoxy resin and oxetane resin, polyamide, polyimide, polybenzoxazole, and polysilane. , Polysilazane, silicone resin, fluororesin, polyurethane, polyolefin resin, polybutadiene, polyisoprene, polychloroprene, polyester such as PET and PBT, polyethylene succinate, polysulfone, polyether, and benzocyclobutene resin Cyclic olefin resins such as norbornene resins can be mentioned, and one or more of these can be used in combination (as a polymer alloy, a polymer blend (mixture), a copolymer, etc.).

The thickness _{T 51} of the resin layer 51 is not particularly limited, for example, is preferably from 10～1500Myuemu, and more preferably 15～1000Myuemu. By setting the thickness T ₅₁ of the resin layer 51 within the above range, to mitigate the irregularities of the surface of the optical functional resin coated layer 50, it is possible to suppress the external haze.

The polarizing layer 53 has a function of extracting linearly polarized light having a plane of polarization in a predetermined direction from the incident light L (natural light that is not polarized). As a result, the incident light L incident on the eye through the spectacle lens 3 with the resin layer is polarized.

The degree of polarization of the polarizing layer 53 is not particularly limited, but is preferably, for example, 50 to 100%, more preferably 80 to 100%. The visible light transmittance of the polarizing layer 53 is not particularly limited, but is preferably 7% to 60%, more preferably 8 to 50% or less, for example.

The constituent material of such a polarizing layer 53 is not particularly limited as long as it has the above functions, but for example, polyvinyl alcohol (PVA), partially formalized polyvinyl alcohol, polyethylene vinyl alcohol, polyvinyl butyral, polycarbonate, ethylene- A polymer film composed of a partially ken-valent product of a vinyl acetate copolymer, which is uniaxially stretched by adsorbing and dyeing a bicolor substance such as iodine or a bicolor dye, a dehydrated product of polyvinyl alcohol, or poly. Examples thereof include a polyene-based oriented film such as a dehydroxated product of vinyl chloride.

Among these, the polarizing layer 53 is preferably a polymer film containing polyvinyl alcohol (PVA) as a main material, which is adsorbed and dyed with iodine or a dichroic dye and uniaxially stretched. Polyvinyl alcohol (PVA) is a material having excellent transparency, heat resistance, affinity with iodine or a dichroic dye as a dye, and orientation during stretching. Therefore, the polarizing layer 53 using PVA as a main material has excellent heat resistance and polarization ability.

Examples of the dichroic dyes include chloratin fast red, congo red, brilliant blue 6B, benzopurine, chlorazole black BH, direct blue 2B, diamine green, chrysophenone, sirius yellow, direct first red, and acid black. And so on.

The thickness T ₅₃ of the polarizing layer 53 is not particularly limited, and is preferably, for example, 5 to 60 μm, more preferably about 10 to 40 μm. If the polarizing layer 53 is too thick, the optical resin layer 5 as a whole tends to be thick, although it depends on the constituent materials thereof. On the other hand, if the polarizing layer 53 is too thin, the polarizing ability may be insufficient.

The bonding layer 54a has a function of bonding the optical resin layer 5 to the spectacle lens 4. Further, the bonding layer 54b has a function of bonding the resin layer 50 with an optical function and the polarizing layer 53. Since the bonding layer 54a and the bonding layer 54b have the same configuration, the bonding layer 54a will be described below as a representative.

The bonding layer 54a is made of a light-transmitting pressure-sensitive adhesive. The above-mentioned pressure-sensitive adhesive is not particularly limited, and may be any of, for example, an acrylic pressure-sensitive adhesive, a silicone-based pressure-sensitive adhesive, and the like. Those capable of exhibiting higher adhesive strength to the body material are preferable.

As the acrylic pressure-sensitive adhesive, a polymer mainly composed of a low Tg main monomer component that gives adhesiveness, a high Tg comonomer component that gives adhesiveness and cohesiveness, and a functional group-containing monomer component for cross-linking and adhesiveness improvement. Or it consists of a copolymer.

Examples of the main monomer component include acrylic acid alkyl esters such as ethyl acrylate, butyl acrylate, amyl acrylate, 2-ethylhexyl acrylate, octyl acrylate, cyclohexyl acrylate, and benzyl acrylate, and butyl methacrylate and methacrylic acid. Examples thereof include methacrylic acid alkyl esters such as 2-ethylhexyl acid, cyclohexyl methacrylate, and benzyl methacrylate.

Examples of the comonomer component include methyl acrylate, methyl methacrylate, ethyl methacrylate, vinyl acetate, styrene, acrylonitrile and the like.

Examples of the functional group-containing monomer component include carboxyl group-containing monomers such as acrylic acid, methacrylic acid, maleic acid, and itaconic acid, 2-hydroxyethyl (meth) acrylic acid, and 2-hydroxypropyl (meth) acrylic acid. , N-methylol acrylamide and other hydroxyl group-containing monomers, acrylamide, methacrylic acid, glycidyl methacrylate and the like.

The reason why such a material is preferable is that it has excellent adhesive strength and cohesive strength, is highly stable against light and oxygen because there is no unsaturated bond in the polymer, and is suitable for the application by selecting the type and molecular weight of the monomer. This is because arbitrary quality and characteristics can be obtained.

Examples of the silicone-based pressure-sensitive adhesive include dimethylsiloxane-based and diphenylsiloxane-based adhesives.

_{The thickness T 54} of the bonding layer 54a is not particularly limited, and is preferably, for example, 2 to 50 μm, more preferably 5 to 35 μm.

With such a bonding layer 54a, the optical resin layer 5 can be arranged on the spectacle lens 4.

As shown in FIG. 2, the protective layer 55 is located on the outermost layer of the spectacle lens 3 with a resin layer, that is, on the front side, and protects the spectacle lens 3 with a resin layer, particularly the resin layer 50 with an optical function. Can be done.

The constituent material of the protective layer 55 is not particularly limited, and is, for example, a polyester resin such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), or polyethylene naphthalate (PEN), or a polyolefin resin such as polyethylene or polypropylene. Various resin materials such as resins, polyimide-based resins, polyamide-based resins, polycarbonate-based resins, polyurethane-based resins, acrylic resins such as polymethylmethacrylate, acetate-based resins, allyl-based resins, and silicon-based resins can be mentioned. Among them, those mainly made of polyamide-based resin, polycarbonate-based resin, polyurethane-based resin, acrylic-based resin, allyl-based resin, and silicon-based resin are preferably used.

The protective layer 55 made of these constituent materials can reliably protect the resin layer 50 with an optical function.

In particular, in the case of excellent heat resistance, it is preferable to use a polycarbonate resin, an allyl resin, a silicon resin or the like.

Further, in the case of having excellent impact resistance, it is preferable to use a polyamide resin, a polycarbonate resin, a polyurethane resin or the like.

Further, in the case of excellent wear resistance, it is preferable to use an allyl resin, a silicone resin, a polyurethane resin or the like.

Further, in the case of having excellent weather resistance, it is preferable to use an acrylic resin, a silicon resin or the like.

Further, in the case of excellent chemical resistance, it is preferable to use a polyamide resin or the like.

Further, the above resin material has a relatively small coefficient of thermal expansion. Therefore, even if the sunglasses 1 are used in a place where the temperature is relatively high, it is possible to prevent the protective layer 55 from being deformed by heat and peeling off from the resin layer 50 with an optical function. Further, since the resin material as described above has a relatively high light resistance, it is possible to prevent the protective layer 55 from deteriorating even if the sunglasses 1 are used for a long period of time. Further, according to the protective layer 55, the unevenness of the surface of the resin layer 50 with an optical function can be alleviated and the external haze can be suppressed.

The thickness _{T 55} of such a protective layer 55 is not particularly limited, for example, 10 [mu] m or more, but preferably not more than 800 [mu] m, 30 [mu] m or more, more preferably 500μm or less.

By setting the thickness T ₅₅ of the protective layer 55 within the above range, to mitigate the irregularities of the surface of the optical functional resin coated layer 50, it is possible to suppress the external haze.

The thickness _{T 5} of the optical resin layer 5 is preferably from 0.1 to 3.0 mm, and more preferably 0.5 to 1.5 mm. Further, the thickness T ₄ of the spectacle lens 4 is preferably 20 to 100%, more preferably 25 to 70%.

If the thickness of the optical resin layer 5 is too thick, the flexibility may be impaired, depending on the constituent materials. On the other hand, if the optical resin layer 5 is too thin, slack or wrinkles may occur when the optical resin layer 5 is bent and deformed.

Further, since the optical resin layer 5 has flexibility, even if the front surface of the spectacle lens 4 is a curved convex surface as shown in FIG. 3, it can be arranged following the shape. .. That is, the optical resin layer 5 can be arranged regardless of the shape of the surface of the spectacle lens 4. Therefore, the optical resin layer 5 is excellent in versatility.

The bonding layer 54a may be covered with a release sheet before being arranged on the spectacle lens 4. By peeling off the release sheet from the bonding layer 54a when arranging it on the spectacle lens 4, dust adheres to the bonding layer 54a or the adhesive strength is reduced before arranging the optical resin layer 5 on the spectacle lens 4. It is possible to prevent it from happening.

The release sheet is not particularly limited, and for example, a film made of various resins such as polyethylene terephthalate, polybutylene terephthalate, polyethylene, polypropylene, and polyarylate, polyethylene laminated paper, clay coat paper, glassin paper, recycled paper, and the like. Various paper materials of the above can be used as a base material, and a material having a mold release treatment applied to the joint surface of the base material with the joint layer 54a can be used. In this case, typical examples of the mold release treatment include coating and forming a mold release agent layer made of a mold release agent such as a silicone resin, a long-chain alkyl resin, and a fluororesin.

Next, the first color material layer 56a and the second color material layer 56b will be described. Since the first color material layers 56a and 56b have the same configuration except that the colors are different, the first color material layer 56a will be described below.

The color material layer 56a has a resin material 561 having light transmittance and a color material 562 filled in the resin material 561.

The resin material 561 is not particularly limited as long as it has light transmittance, and for example, a cyclic ether resin such as an acrylic resin, a methacrylic resin, a polycarbonate, a polystyrene, an epoxy resin, or an oxetane resin. Polyamide, polyimide, polybenzoxazole, polysilane, polysilazane, silicone resin, fluororesin, polyurethane, polyolefin resin, polybutadiene, polyisoprene, polychloroprene, polyester such as PET and PBT, polyethylene succinate, polysulfone, polyether In addition, cyclic olefin-based resins such as benzocyclobutene-based resins and norbornene-based resins can be mentioned, and one or more of these can be combined (polymer alloy, polymer blend (mixture), copolymer, etc.). As) can be used.

The transmittance of visible light in the color material layer 56a is preferably 80% or less, and more preferably 70% or less. As a result, when viewed from the outside, the reflected color of the color material layer 56b can be seen well, and a vivid color can be introduced into the 56b.

Examples of the coloring material 562 include acid dyes, direct dyes, reactive dyes, basic dyes, and the like, and one or a combination of two or more selected from these can be used.

Types of pigments include inorganic pigments, organic pigments, metallic pigments, etc., which can improve designability. Two or more kinds of these colorants may be blended. For example, dyes such as red, green, and yellow may be combined.

Examples of the inorganic pigment include titanium oxide, carbon black, titanium yellow, iron oxide pigment, ultramarine, cobalt blue, chromium oxide, spinel green, lead chromate pigment, zinc oxide pigment, cadmium pigment and the like. ..

Examples of organic pigments include azo lake pigments, benzimidazolone pigments, dialilide pigments, condensed azo pigments, phthalocyanine pigments such as phthalocyanine blue and phthalocyanine green, isoindolinone pigments, quinophthalone pigments, quinacridone pigments, and perylene. Examples thereof include pigments, anthraquinone pigments, perinone pigments, and condensed polycyclic pigments such as dioxazine violet.

Metallic pigments include, for example, flaky aluminum metallic pigments, spherical aluminum pigments used to improve weld appearance, mica powder for pearl-like metallic pigments, and other inorganic polyhedron particles such as glass. Examples thereof include those obtained by coating metal with plating or sputtering.

Specific examples of the dye include, for example, C.I. I. Acid Yellow 17, 23, 42, 44, 79, 142, C.I. I. Acid Red 52,80,82,249,254,289, C.I. I. Acid Blue 9,45,249, C.I. I. Acid Black 1,2,24,94, C.I. I. Hood Black 1, 2, C.I. I. Direct Yellow 1,12,24,33,50,55,58,86,132,142,144,173, C.I. I. Direct Red 1,4,9,80,81,225,227, C.I. I. Direct Blue 1,2,15,71,86,87,98,165,199,202, C.I. I.

By the way, conventionally, for example, when a red-colored object is viewed while wearing sunglasses with a red lens, it may be difficult to grasp the color of the object itself. It is considered that this is because the red color of the object being viewed is less noticeable to the wearer of sunglasses because the surrounding scenery is also all red. This applies not only to red lenses but also to lenses such as blue and yellow.

In particular, regarding the color visibility of traffic lights, for example, "AMERICAN NATIONAL STANDARD (ANSI Z 80.3-2010)", "ISO (12312_12)", "Australian / New Zealand Standard (AS / NZS 1067-2009)", etc. The standard defines the color of the lens, that is, the color over the entire field of view of the wearer. For this reason, conventional sunglasses have a limitation on the color of the lens and a limitation on the width of the design.

According to the present invention, the above problems can be solved and the range of design can be expanded. This will be described below.

As shown in FIG. 2, in the optical resin layer 5, the color material layer 56a and the color material layer 56b are different in color from each other. In the following, as an example, a case where the color of the color material layer 56a is green and the color of the color material layer 56b is red will be described.

If the color material layer 56a is omitted, when the wearer looks outside through the sunglasses 1, the entire field of view looks red, but in the optical resin layer 5, the back side of the color material layer 56b is covered with. A green color material layer 56a is provided which has a complementary color relationship with the color material layer 56b, that is, is 180 ° away from red in the hue circle described later. As a result, when the wearer looks outside through the sunglasses 1, the entire field of view looks like a color (composite color) in which the color material layer 56a and the color material layer 56b, which are in a complementary color relationship, are combined. That is, the red color is offset by the green color, and as a result, the visual field appears gray to the wearer as a whole. Therefore, even if the lens looks red when viewed from the outside, it is possible to prevent the entire field of view of the wearer from becoming red. As a result, for example, when the wearer sees a red light, the color can be clearly recognized.

In the above description, the case where the color material layer 56b is red has been described, but it goes without saying that the present invention is not limited to this.

Thus, according to the present invention, the wearer's field of vision can be gray regardless of the color when viewed from the outside. As a result, high color distinctiveness can be maintained regardless of the color when viewed from the outside of the lens. Therefore, the design can be enhanced and the high color distinctiveness can be ensured.

In the above description, the case where the colors of the color material layers 56a and 56b have a complementary color relationship has been described, but these colors can exert the above effect even if they are slightly different from the complementary color relationship. Hereinafter, this will be described with reference to FIG.

FIG. 4 is a diagram showing a hue circle in the Munsell hue system. This color wheel is illustrated as a circle centered on the intersection of ^{the a *} and b ^* axes that are orthogonal to each other. On the a ^* axis, the right side (+ a ^* side) in the figure is red, and the left side (-a ^* side) in the figure is green. On the other hand, on the b ^* axis, the upper side (+ b ^* side) in the figure is yellow, and the lower side (-b * side) in the figure is purple. Further, in this color wheel, the above four colors are continuously changed along the circumferential direction. Then, in this color wheel, the saturation becomes higher as the distance from the center increases, and the saturation becomes zero at the center, that is, the color becomes gray (gray).

The color (hue) of the color material layer 56a of the optical resin layer 5 shown in FIG. 2 and the color (hue) of the color material layer 56b are separated from each other by 90 to 270 ° around the center S in the color wheel shown in FIG. It is preferably separated by 120 to 240 °, more preferably separated by 150 to 210 °. As a result, the color of the color material layer 56b is offset by the color of the color material layer 56a, and as a result, the wearer's field of view becomes substantially gray as a whole. Therefore, high color distinctiveness can be maintained.

Further, the saturation of the color material layer 56b is preferably larger than the saturation of the color material layer 56a. That is, the distance from the center S of the color coordinate B of the color material layer 56b in the color wheel shown in FIG. 4 is preferably larger than the distance from the center S of the color coordinate A of the color material layer 56a. By increasing the color saturation of the color material layer 56b, the spectacle lens 3 with the resin layer can be made vivid when viewed from the outside. Therefore, the design of the sunglasses 1 can be further enhanced.

<Second Embodiment>
FIG. 5 is an enlarged cross-sectional view showing a second embodiment of the spectacle lens with a resin layer of the present invention.

Hereinafter, the second embodiment of the optical resin layer and the spectacle lens with the resin layer of the present invention will be described with reference to this figure, but the differences from the above-described embodiments will be mainly described, and the same matters will be described. Is omitted.
The present embodiment is the same as the first embodiment except that the number of coloring material layers is different.

As shown in FIG. 5, in the spectacle lens 3A with a resin layer, the optical resin layer 5A includes a bonding layer 54a, a polarizing layer 53, a bonding layer 54b, a resin layer 50 with an optical function, and a coloring material layer 56c. It has a coloring material layer 56d, a coloring material layer 56e, and a protective layer 55, and these are arranged in this order from the lower side (back side).

The color material layers 56c to 56e have different hues from each other, and have the following relationship.

The hue of the color material layer 56c and the color material layer 56d and the hue of the color material layer 56e are preferably 90 to 270 ° apart from each other, and 120 to 240 ° apart from each other in the color wheel. Is more preferable, and it is even more preferable that the distance is 150 to 210 °.

The combined hue of the color material layer 56c and the color material layer 56d refers to the hue when viewed from the thickness direction in a state where these are laminated.

According to such a configuration, the hue of the color material layer 56e can be offset by the two layers of the color material layer 56c and the color material layer 56d. Therefore, the field of view of the wearer is gray as a whole. As a result, it is possible to enhance the design while enhancing the color distinction.

In particular, the design can be changed depending on which color color material layer is arranged on the outside, and high color distinctiveness can be ensured regardless of the arrangement order of the color material layers 56c to 56e.

<Third Embodiment>
FIG. 6 is an enlarged cross-sectional view showing a third embodiment of the spectacle lens with a resin layer of the present invention.

Hereinafter, the third embodiment of the optical resin layer and the spectacle lens with the resin layer of the present invention will be described with reference to this figure, but the differences from the above-described embodiments will be mainly described, and the same matters will be described. Is omitted.
