The invention relates to an opaque, white film with a thickness of from 10 to 500 μm whose principal constituent is a crystallizable thermoplastic. The film comprises at least barium sulfate and at least one optical brightener. The barium sulfate and / or the optical brightener are incorporated directly into the crystallizable thermoplastic or are fed as a masterbatch during film production.

At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.

A method by which optical filter structures may be applied onto a substrate that is transparent to light at least in the visible wavelength range suitable for a barrier filter.In such a method, an adhesive is applied onto the substrate; then, a photographic film comprising a base film and a photographic emulsion layer applied on it is brought into contact with the adhesive. The optical filter structures are impressed in the photographic emulsion layer by exposure, development and fixation. The side of the film brought into contact with the adhesive is the one that bears the photographic emulsion layer. The adhesive is then spread between film and substrate by means of a roller rolling across the film at a specified contact pressure and a specified feed rate of the roller and thus pressing the film against the substrate. A permanent joint between substrate and photographic emulsion layer is then established by the curing of the adhesive. In a further step, the base film may be thermally separated and removed from the photographic emulsion layer.
