摘要:
A dielectric multilayer filter includes a light-transmissive substrate having a flat surface on at least one side with a dielectric multilayer film formed on the flat surface. The dielectric multilayer film reflects light of a particular wavelength. A resin focusing lens is on one side of the light-transmissive substrate.

A non-fluidizable composition readily convertible into a fluidizable composition by slight stress or pressure, which can be prepared by cooling an emulsion comprisinng a water-immiscible fatty acid, water and an emulsifier from a temperature sufficient to keep the emulsion at a fluidizable state while stirring, stopping the stirring at a temperature not lower than the temperature 5.degree. C. below the congealing temperature of the emulsion and further continuing the cooling to room temmperature and is useful as a base for shaving creams, hair creams, adhesive pastes, printers' inks, shoe polishes, etc.
