Description

M299858 VIII. New description: [New technical field] The present invention relates to an optical laminate, and more particularly to an optical laminate capable of stably bonding between layers. The present invention also relates to a lens comprising the optical laminate. [Prior Art] Referring to FIG. 1, a general lens 1 includes a substrate ii and an optical laminate 12 disposed one on another, and the optical laminate 12 includes a support that is coupled to the substrate 11. The layer 121, a film layer 122 disposed on the support layer 121, and a hardened layer 123 disposed on the film layer 122. Therefore, the lens 1 can be said to be formed by sequentially stacking the above layers. In general, the lens 1 is formed by first forming a portion other than the hardened layer 123 of the optical laminate 12, which is a polymer transparent film as the support layer 121, and then forms a film on the support layer 121. After layer i 22 is formed; afterwards, it is placed in a pre-press molding machine, and subjected to high temperature and compression molding, and after bending and forming, the polymer material of the desired material is selected, and then an injection molding step is used. The polymer raw material particles are attached to the support layer 121 to form the base material η; and the hardened layer 123 is applied to a solution containing a monomer containing siloxane or thioacrylic acid. After the film layer 122 is formed, the hardened layer 123 is formed by heating or UV light to obtain the lens 1. In practice, since the hardened layer 123 is used to protect the film layer 122, it is determined depending on the needs of the manufacturer, but in general, the hardened layer 123 is a required component. For the above-mentioned polymer transparent film, 5 M299858 manufacturers can also use polarizing, such as PVA polarizing film (pQiyvinyi alc〇h〇1 polarized fllm), PET polarizing film, polyester polarizing film, etc. Providing a film layer 122 containing a photochromic dye to produce a lens having both "polarization" and "photochromic" characteristics, such that the lens 1 prevents glare from reaching the eyes and With the ultraviolet rays in the environment, it is dark or light in color, and at the same time, it can isolate the glare and glare of the user from the glare and glare, and prevent the luminosity Φ / lesion in the lens of the eyeball. 'And the melanin was destroyed. Such lenses are widely used as flat lenses, singie lenses, bifocal lenses (bif〇cal (10), progressive multifocal lenses (pn)_Sive lenses (The above three lenses can be used as ophthalmic prescription lenses such as myopia lenses or presbyopic lenses), in-vehicle sun visors, vehicle windshields, or in windows, door panels, etc., which have great market demand. Further, in order to meet the needs of the consumer, the manufacturer can not only prepare the lens i having the four-layer body as shown in FIG. 1, but also can prepare the lens with more layers according to the needs thereof, for example, the substrate. 11 another photonic layer deposit 12 is reversely added to form a seven-layered lens (not shown) formed by sandwiching a substrate 11 between the two optical laminates 12, and the material of each layer is The various operating parameters at the time of preparation are of course self-determined by those skilled in the art by virtue of their professionalism and needs. However, in the lens 1 obtained by the above-described production method, the film layer 122 and the cut layer m which are originally connected to each other are easily mutually woven (hereinafter, a similar condition is referred to as interlayer peeling phenomenon), resulting in poor weather resistance of the lens 1. The life expectancy is not long. The Xianli industry has tried to improve this problem by modifying the surface of the plasma, applying the adhesive to the 6 M299858 core, and roughening the surface. It is intended to increase the connectivity of the layers to avoid peeling. The effect is not good, or it may lead to other undesired negative effects, such as bonding the layers with glue. It is easy to make the optical degree and the lens of the obtained lens not comply with the US and European optical lens regulations.

US Patent No. 6,759,090 B2 discloses that more than 10% of Na〇H (called = applied to the surface of layer 122 or branch 121) to roughen it: the contact area between the layers is increased, and the optical stack is relatively raised. In the material layer, the film layer 122 is connected to the support layer 121 and the hardened layer 123 to the film layer (2). Although this method can reduce the probability of occurrence of the peeling phenomenon, the surface of the layer bodies 121 and 122 is thick. The phenomenon of diffusing light caused by undesired light makes the optical quality of the manufactured lens poor. Therefore, how to improve the life of the lens and meet the optical lens regulations of the United States and Europe, in order to provide better quality, especially It is not easy to occur between layers

It is an urgent task for the industry to solve the problem of peeling off the lens to the masses of consumers to meet their needs. [New content] Based on the interlayer peeling phenomenon that the conventional lens 1 will produce, and considering that the main constituent materials of each layer in the optical layer are polymers, Shen Qing speculates that the optical laminate in Fig. 1 In the structure of 12, if a layer of the original two mutually connected layers (for example, the support layer 121 and the film layer 122) is formed, a polymer interposed between the two layers is formed. The mesh transition structure should greatly increase the degree of connection between the two layers to reduce the probability of occurrence of interlayer peeling. 7 M299858

In 疋, the applicant attempts to cast a plastic suspension containing a monomer or a prepolymer and a solvent in addition to a dye that absorbs light, and the plastic solution is in contact with the layer. After a certain period of time, the layer body is wetted by the solvent and is swollen (hereinafter referred to as "swelling"), so that the solute in the plastic solution penetrates into the support layer and the surface of the support layer is wetted. The part is formed - the infiltrated part, and the uninfiltrated part is - support. ρ, on the same day, a plastic layer composed of a plastic solution is formed on the wetted portion, and then the wetted portion and the plastic layer are subjected to heat treatment or uv light treatment, and the monomer or prepolymer is polymerized. At this time, the plastic layer covering the impregnated weir forms a film layer having a specific function such as photochromic or melanin protection or infrared protection depending on the type of dye to be added, and the infiltrated portion The newly formed polymer and the original polymer in the branch body are intertwined and entangled, and thereby formed - a polymer interpenetrating network (interpenetrating p〇ly bribe (10) Xiaok, nickname (4)) Through the layer, the interpenetrating layer is a transitional structure of the strengthened joint, which can achieve the purpose of improving the degree of connection between the layers. In this way, the optical laminate is formed, and a stable bonding layer (ie, an interpenetrating layer) is formed at the same time as the film layer is formed, so that no additional modification or roughening step is required, which not only simplifies the process steps but also causes (10) The special structure makes the bonding force between the film layer and the selective layer body far beyond the conventional lens. Therefore, the present invention provides an optical laminate which is structurally stable and is not easily peeled off between layers, and includes a support portion and a portion. The support portion includes a support polymer. The first attachment portion includes a first interpenetrating layer disposed on the supporting portion, and a first film disposed on the first interpenetrating sound layer 6 away from the support portion of the 8 M299858 The first film layer comprises a light absorbing first dye and a first and second interpenetrating layer, the first interpenetrating layer comprising the supporting polymer and a first polymer interpenetrated therewith.曰 In a second aspect, the present invention provides a lens comprising a substrate and an optical laminate as described above. The substrate is comprised of a substrate polymer and the optical laminate is disposed on the substrate. 〇 Through the above-mentioned preparation concept, in the optical layer, the first film layer which is originally only connected to each other is reversed, and the two layers of the polymer in the first interpenetrating layer are closely intertwined. And very firmly knot each other: and avoid peeling off each other. Further, the above concept of permeating and further forming the interdental polymer network (ie, the interpenetrating layer) and the film layer can also be used as other layer bodies, such as the setting of the hardened layer, and the hardened layer can be enhanced by the same reason: Adhesion 'avoids the phenomenon of interlayer peeling, increases weather resistance, and greatly improves the life of the lens or optical laminate. Since the novel optical laminates and lenses have a very stable structure and a long service life, the preparation methods thereof are also very simple, and the various advantages are in line with the needs of the industry, so that they can be practically applied and created.
