  • a polarization component which is monotonously increased with respect to the angle of reflection.
  • the above-mentioned optical items utilize a phenomenon that when a polarizer is used such that an absorption axis thereof is horizontal, such a polarization component can be cut. Light can be described and behave by two straight polarizations perpendicular to each other.
  • a vibration component of light which is in a plane including the incident light and the normal direction thereto is p polarization
  • a component vibrating in a plane perpendicular to the above-mentioned plane is s polarization

  • transparent optical items such as sunglasses, goggles, corrective lenses and the like including a layer containing a photochromic colorant and thus having photochromic performance of being colored under external light containing a large amount of ultraviolet rays and of being colorless under artificial light containing a small amount of ultraviolet rays.
  • a known polarizer usable for these items is formed of a resin film, typically, a poly(vinyl alcohol) (PVA) film. Such a film is stretched in one direction while being dyed with iodine or a dichroic dye and thus is provided with polarization properties.
  • PVA poly(vinyl alcohol)
  • Known methods for providing such a film with photochromic performance include (1) a method of using a polymer solution containing a photochromic colorant to form a casting film; (2) a method of melt-extruding a thermoplastic polymer containing a photochromic colorant to form a film; (3) a method of preparing and using a composition for forming a film, the composition containing a photochromic colorant; (4) a method of preparing and using an adhesive composition containing a photochromic colorant; (5) a method of thermally diffusing a photochromic colorant in a film or a substrate to form a photochromic diffusion layer; and the like (e.g., Patent Document 1).
  • One method for applying any of the functional layers described above to optical items such as sunglasses, goggles, corrective lenses and the like uses a functional sheet including protective layers on both surfaces of a layer having polarization properties, a layer having photochromic properties, or a layer having both of these properties.
  • thermoplastic resin examples include aromatic polycarbonate, polymethylmethacrylate, transparent nylon, acetyl cellulose and the like.
  • aromatic polycarbonate is used from the viewpoint of impact resistance.
  • Polymethylmethacrylate, transparent nylon, hydrocarbon-based resins having an alicyclic substance as a main chain, acetyl cellulose and the like are used from the viewpoints of crack resistance, fashionability, and various other requirements.
  • a functional layer and a protective layer are integrated together usually by use of a curable resin adhesive, but troubles sometimes occur due to adhesion failure between the functional layer and the protective layer.
  • Aromatic polycarbonate has a problem of causing solvent cracks. Therefore, depending on the solvent used, an adhesive layer cannot be formed on the layer of aromatic polycarbonate, and moreover, the remaining solvent causes cracks. However, if excessive drying is performed for the purpose of removing the solvent, the adhesive strength is usually weakened. There are also limitations on forming an adhesive layer on both adherend surfaces of aromatic polycarbonate for the purpose of realizing strong adhesion.
  • thermosetting lens using a functional sheet there are methods by which a film resistant against a curable resin monomer solution is formed on a surface of a functional sheet, for example, a film of a curable acrylic-based resin or the like is formed on a surface of a functional sheet (Patent Documents 2 and 3).
  • An optical item such as sunglasses, goggles, corrective lenses or the like using the above-mentioned functional sheet is usually produced as follows. First, the functional sheet is molded to be a lens which is curved as desired. Alternatively, the functional sheet is molded to be a bent item having a curved surface, then the bent item is attached to a mold, and a rear surface thereof is provided with a transparent plastic material by means of injection molding, thereby forming a lens. The lens obtained by either method is subjected to hard-coating, reflection prevention, and any other surface treatment when desired. Then, the steps of shaping the lens to fit into the frame (external shape processing), drilling holes, and tightening with screws, and the like are conducted. In this manner, the optical item is assembled.

  • abrasion on the surface layer of the transparent plastic material is a problem.
  • the material is not highly resistant against abrasion, a product having scratches is liable to be provided, which lowers the production yield.
  • a functional sheet including an aromatic polycarbonate layer which is highly impact resistant, is easily scratched. Therefore, such a functional sheet is, for example, hard-coated after being produced (Patent Document 4).
  • Patent Document 5 describes that a protective layer formed of a (meth)acrylic-based resin may have an insufficient mechanical strength or the like, and thus a polycarbonate-based resin layer is provided on an outer surface of a (meth)acrylic-based resin forming a protective layer so that the polycarbonate-based resin layer acts as an outer surface of the functional sheet.

  • the lens is subjected to bending processing, then attached to a mold and subjected to injection molding so as to form a molded lens
  • the scratches or the like on the surface in contact with the injection-molded resin are usually erased by the melt resin.

  • the conditions for these steps are the same as much as possible for the surface of the injection-molded resin and the opposite surface.
  • the opposite surface has substantially the same properties as those of the surface adhering to the functional layer (inner surface). Since the opposite surface is pressed to the mold by the pressure of the resin during the injection molding and is also surface-treated, minute scratches or the like on the opposite surface are erased.

  • a film or sheet of aromatic polycarbonate resin having a high retardation value also has a disadvantage of being inferior in the crack resistance to a film or sheet having a small residual stress.
  • a conventional sheet or film formed only of an aromatic polycarbonate resin having a high retardation value of 3000 nm or greater is produced by the following method.
  • the aromatic polycarbonate resin of a temperature higher than the glass transition temperature is delaminated from the roll, and the resin is stretched and cooled, so that the amount of stretching is controlled.
  • a co-extruded sheet or film having an improved surface hardness used in the present invention and having a high retardation value is not industrially produced.
