In some cases, the same reference numerals are assigned to the same members and portions. FIG. 1 is a schematic view partially showing an example of a method of holding and fixing an eyeglass lens by a fixing chuck in the method of polishing a lens for eyeglasses of the present invention. In Fig. 1, 1 is a lens for eyeglasses, la is a surface on the convex side of the lens for eyeglasses 1 (convex surface), lb is a surface on the concave side of the lens for eyeglasses 1 (concave surface), and lc is a lens for eyeglasses 1 is the outer peripheral portion (outer peripheral surface), 2 is the convex side fixing chuck, 2a is the convex side fixing chuck, 2 is the convex side fixing functional portion at the tip of the 2nd end, 3 is the concave side fixing chuck, and 3a is the concave side. A concave-side fixing function portion at the tip of the fixing chuck 3 is a pressure-sensitive adhesive sheet. In the method of fixing the spectacle lens by the fixing chuck shown in FIG. 1, the convex surface la of the spectacle lens 1 and the convex fixing function section at the tip of the convex fixing chuck (fixing chuck) 2 are used. (Fixing function section) An adhesive sheet 4 is interposed between 2a and the concave surface on the concave surface lb of the lens 1 for eyeglasses. The fixed function part (fixed function part) 3a is directly fitted, and the spectacle lens 1 is fixed to the polishing apparatus in a form sandwiched between the fixed function parts of the fixing chucks (2, 3). Specifically, an adhesive sheet 4 is affixed to the convex surface la of the eyeglass lens 1, and the fixing function part 2 a of the fixing chuck 2 is joined to the back surface of the adhesive sheet 4.

That is, in the method of fixing the spectacle lens according to FIG. 1, the convex function surface la side of the spectacle lens 1 directly connects the fixing function part 2a at the tip of the fixing chuck 2 to the surface la of the spectacle lens 1. Instead, it is bonded via the adhesive sheet 4 and has a fixing function by adhesiveness (or adhesiveness) to the surface la of the adhesive sheet 4 and a fixing function (adhesive property) of the fixing function portion 2a to the adhesive sheet 4. And sticky (Fixing property). As described above, in the present invention, at least one surface side of the eyeglass lens is a combination of a plurality of fixing functions of the fixing function of the adhesive sheet and the fixing function of the fixing function unit. The chuck can be firmly adhered to the surface of the eyeglass lens.

(Fixing chuck)

Known or commonly used fixing chucks can be used as the fixing chucks (2, 3), and the fixing chucks used in conventional eyeglass lens polishing apparatuses can be used as they are. Specifically, as the fixing function part 2a at the tip of the fixing chuck 2, a fixing function part having an adsorptive property or an adhesive property is used.

Since the fixing function part 2a has an adsorbing property or an adhesive property, and the fixing chuck 2 is firmly adsorbed or adhered to the surface la of the eyeglass lens 1 via the adhesive sheet 4, the fixing chuck 3 It is not necessary to adhere to the spectacle lens 1 as strongly as the fixing chuck 2, and it is sufficient that the fixing chuck 2 has such a frictional property as to prevent displacement during polishing. Therefore, even if the fixing function part 3a has viscoelasticity, the fixing function can be sufficiently exhibited. However, in order to further firmly fix the eyeglass lens, the fixing function part 3a has an adsorbing property and an adhesive property. You can use something.

Note that the fixed function unit 2a and the fixed function unit 3a can be made of the same type of member and have different types of member forces.

At this time, the fixing function part (2a, 3a) can be provided on the fixing chuck in the form of an adapter. In the method of installing the fixed function unit in the form of an adapter, the fixed function unit can be appropriately selected according to the type of the eyeglass lens. Of course, in the case where the fixing function part is provided so as to be inseparable from the fixing chuck, by appropriately selecting the fixing chuck itself, the fixing function part corresponding to the type of eyeglass lens can be obtained. What is necessary is just to become.

The size of the fixing function portion (for example, the bonding surface area to be bonded to the glasses lens or the adhesive sheet) is not particularly limited, and the type of the polishing apparatus, the size of the glasses lens, and the size of the adhesive sheet. It can be appropriately selected according to the size and the like.

The surface antifouling coating agent may be used alone or in combination of two or more.

The surface antifouling coating agent is not particularly limited, and various surface antifouling coating agents can be used, and a fluorine surface antifouling coating agent is particularly preferable. Fluorine-based antifouling coating agents can exhibit excellent antifouling properties. As such a fluorine-based surface antifouling coating agent, for example, a fluorine-based surface antifouling coating agent containing a silane-based compound is suitable. Examples of the fluorine-based surface antifouling coating agent containing a silane compound include C ₈ F ₁₇ CH ₂ CH ₂ Si (OCH ₃ ) ₃ and C ₈ F ₁₇ CH ₂ CH ₂ CH ₂ Si (OC ₂ H ₅ ) ₃ , C ₃ F ₇ 0— (C ₃ F ₆ 〇) _n — C ₂ F ₄ — CH ₂ CH ₂ _Si (OCH ₃ ) ₃ , C ₈ F ₁₇ CH ₂ CH ₂ Si (NH) _3/2, etc. Is mentioned.

Specifically, examples of the fluorine-based surface antifouling coating agent include “Optool D SXJ made by Daikin Industries, Ltd.” and the like. When the surface antifouling treatment is performed as described above, the antifouling property is exerted by increasing the contact angle of water on the surface of the spectacle lens or decreasing the friction coefficient. In other words, by applying the surface antifouling treatment to the spectacle lens, the contact angle of the surface of the spectacle lens on which the antifouling treatment has been performed (antifouling treatment surface) with water can be increased. The coefficient of friction (for example, the coefficient of friction of the antifouling treatment surface against the steel ball) can be reduced.

The contact angle of water on the surface subjected to the surface antifouling treatment (measured by a droplet method using a contact angle meter) is preferably 109 ° or more. If the contact angle is less than 109 °, the antifouling property of the surface is low.

Adhesives based on styrene block copolymer rubber, recycled rubber, butyl rubber, polyisobutylene, etc.) are included.

In the pressure-sensitive adhesive layer, in addition to the pressure-sensitive adhesive polymer (base polymer), various additives such as crosslinking agents (for example, isocyanate-based crosslinking agents, epoxy-based crosslinking agents, urea-based crosslinking agents, melamine-based crosslinking agents, Carboxylic acid or acid anhydride based crosslinking agents, metal compound based crosslinking agents, etc.), tackifiers [for example, terpene resins (terpene resins, terpene phenol resins, aromatic modified terpene resins, hydrogenated terpene resins, etc.), Petroleum resin (aliphatic, aromatic, alicyclic), rosin-based resin (rosin, hydrogenated rosin ester, etc.), coumarone'indene resin, styrene-based resin, etc.), surfactant (phosphate ester-based, Anionic surfactants such as sulfates, sulfonic acids, and carboxylic acids; cationic surfactants such as amine salts and quaternary ammonium salts IJ; Ester, ether Surfactants, such as nonionic surfactants such as carboxybetaine, glycine, etc.), plasticizers, antioxidants, coloring agents, antistatic agents, fillers, etc. A foaming agent and the like may be included.

The pressure-sensitive adhesive sheet can be produced by forming a pressure-sensitive adhesive layer on at least one surface of a substrate by using a conventional method such as a coating method. Specifically, for example, a method of applying an adhesive on a substrate or the like, a method of applying an adhesive on a suitable separator (such as release paper) to form an adhesive layer, A pressure-sensitive adhesive sheet can be produced by a method such as a method of transferring the above pressure-sensitive adhesive layer onto a substrate or the like.

The pressure-sensitive adhesive sheet may have another layer in addition to the base material and the pressure-sensitive adhesive layer, if necessary. For example, one or more intermediate layers can be provided between the substrate and the pressure-sensitive adhesive layer. Examples of the intermediate layer include a coating layer of an undercoating agent for the purpose of improving the adhesion between the substrate and the pressure-sensitive adhesive layer. The pressure-sensitive adhesive sheet can have a form such as a sheet shape or a tape shape. For example, if the pressure-sensitive adhesive sheet is composed of a base material, a pressure-sensitive adhesive layer formed on one surface of the base material, and a back treatment layer formed on the other surface of the base material, The pressure-sensitive adhesive sheet may be a pressure-sensitive adhesive sheet in which the surface of the pressure-sensitive adhesive layer is superimposed on the back surface of the sheet (for example, the surface of the rear surface treatment layer) and laminated in a sheet shape, or a pressure-sensitive adhesive sheet wound in a roll shape. It can be manufactured as As described above, when the base material, the pressure-sensitive adhesive layer formed on one surface of the base material, and the back surface treatment layer formed on the other surface of the base material, The sheet can be manufactured by forming a pressure-sensitive adhesive layer on one side of the substrate and forming a back surface treatment layer on the other side using a conventional method such as a coating method. By laminating the surface of the agent layer on the back surface of the sheet and laminating it in a sheet or winding it in a roll, an adhesive sheet laminated in a sheet or a pressure-sensitive adhesive sheet wound in a roll can be produced. When a plastic film made of a non-polar polymer such as an olefin resin such as polyethylene or polypropylene is used as the base material, the adhesion of the base material itself does not occur even if the base material does not have a back surface treatment layer. By using the releasability of the adhesive layer, it is possible to form an adhesive sheet laminated in a sheet shape or an adhesive sheet wound in a roll shape with a force S.

Further, the pressure-sensitive adhesive sheet may be used when the back surface of the base material is not subjected to the back surface treatment, when the base material has no releasability with respect to the pressure-sensitive adhesive layer, In the case of a substrate-less double-sided pressure-sensitive adhesive sheet or the like, the pressure-sensitive adhesive layer can be protected by a separator (a release liner). The release liner is not particularly limited. For example, a release agent layer composed of a known or commonly used release agent such as a silicone-based release agent, a fluorine-based release agent, or a long-chain alkyl-based release agent is formed on the substrate surface. Release liner, which itself is highly releasable, plastic film [for example, polyolefin resin finolem such as polyethylene film (linear low-density polyethylene film, etc.), ethylene- _a -olefin copolymer film; Teflon (Registered trademark) film-based release resin liner, etc.], and the material of the highly releasable plastic film is laminated or coated on various substrates (eg, metal foil, heat-resistant plastic film, etc.). And the like.

The adhesive sheet has a 180 ° peel adhesive strength (25mm width, peeling speed 300mmZmin, 23 ° C) to the surface of the lens for spectacles, which is 0.1 IN or more 25mm (preferably 0.15N / 25mm) Above, especially 0.5 N / 25 mm or more). For example, 180 ° peel adhesive strength (25mm width, peeling speed 300mm / min, 23 ° C) of the adhesive sheet to the eyeglass lens is more effective when the IN / 25mm or more is 0. IN / 25mm or more. In addition, the eyeglass lens can be firmly fixed, and positional deviation during polishing can be effectively prevented.

Regarding the size (surface area, etc.) of the adhesive sheet, the surface area to be attached to the glasses lens is larger than the suction or adhesive surface area of the fixing function part at the tip of the fixing chuck joined to the back of the adhesive sheet. Is preferred. Specifically, the surface area of the adhesive sheet adhered to the eyeglass lens is, for example, 1.2 times or more (preferably 1.5 times or more, of the adsorption or adhesive surface area of the fixing function portion at the tip of the fixing chuck. More preferably, it is more than 2 times, especially 2.5 times or more.

If the adhesion surface area of the adhesive sheet to the eyeglass lens is larger than the adsorption or adhesive surface area of the fixing function part at the tip of the fixing chuck to the adhesive sheet, the eyeglass lens will be firmly fixed with more excellent fixing properties. This makes it possible to prevent positional deviation during polishing with an excellent level.

In FIG. 1, since a fixing function part having an adsorbing property or an adhesive property is used as the protrusion-side fixing function part 2a, an adhesive sheet 4 is provided between the protrusion part surface la and the protrusion-side fixing function part 2a. However, the convex side fixing function part 2a is not a suction function or adhesive fixing function part and the concave part fixing function part 3a is a suction function or adhesive fixing function part. In this case, an adhesive sheet can be interposed between the concave surface lb and the concave side fixing function portion 3a.
