Claims (12)

A timepiece dial member made of a laminate composed of a plurality of transparent films made of a resin material having light permeability,
  In the laminate, the adjacent transparent films have different refractive indexes, and among the adjacent transparent films, the first transparent film having a large refractive index is n1, and the second transparent film has a small refractive index. A timepiece dial member, wherein the refractive index ratio n1 / n2 is 1.03 to 1.18, where n2 is the refractive index of the transparent film. 2. The timepiece dial member according to claim 1, wherein a total number of the first transparent film and the second transparent film in the laminated body is 100 to 250. 3.   3. The timepiece dial member according to claim 1, wherein an absolute refractive index of the resin material constituting the transparent film is 1.4 to 1.7.   4. The timepiece dial member according to claim 1, wherein the transparent film has an average thickness of 0.5 to 20 μm.   The timepiece dial member according to any one of claims 1 to 4, wherein the transparent film includes one made of a material containing polyethylene terephthalate and one made of a material containing polypropylene.   The timepiece dial member according to any one of claims 1 to 5, wherein a colored film made of a material containing a colorant is included between the transparent films constituting the laminate.   The colored film made of a material containing a colorant is disposed on the second surface side of the laminate opposite to the first surface side on which the external light is incident. The timepiece dial member described in 1.   The timepiece dial member according to any one of claims 1 to 7, comprising a diffusion film having a function of diffusing incident light between the transparent films constituting the laminated body. The diffusion film having a function of diffusing incident light is disposed on the second surface side of the laminate opposite to the first surface side on which external light is incident. The dial member for timepieces described in 1.   The timepiece dial member according to any one of claims 1 to 9, wherein a transmittance of light incident from a normal direction of the laminated body is 20 to 50%. A timepiece comprising the timepiece dial member according to claim 1. A method for producing a timepiece dial member comprising a laminate in which a plurality of transparent films made of a plurality of resin materials having light transmittance are laminated, wherein the transparent film x made of the resin material X having a large refractive index When the refractive index is nx and the refractive index of the transparent film y made of the resin material Y having a small refractive index is ny, the refractive index ratio nx / ny is 1.03 to 1.18, and the transparent film y is formed on the transparent film x by discharging the liquid constituting the resin material Y using a droplet discharge method and drying or curing with heat or ultraviolet rays. A method for manufacturing a timepiece dial member.
