    • PURPOSE:To provide a pattern such as a character or a designed symbol or the like without distortion onto a surface of the diaphragm for speaker by controlling the distribution state of a paint in which magnetic powder is dispersed through the use of a magnetic force while keeping the property such as stiffness and an internal loss being the requirement of the diaphragm. CONSTITUTION:When a paint 33 in which magnetic powder is dispersed is applied to the surface of a base material 31, a magnet 34 is arranged in the vicinity of the front side or a rear side of the base material 31. The magnetic powder dispersed in the paint formed on the base material 31 in the vicinity of the magnet 34 is oriented by lines of magnetic force of the magnet 34 and a pattern 35 is formed together with the magnetic powder 36 not receiving the effect of lines of the magnetic force. Since the pattern is formed by lines of magnetic force, a prescribed pattern is accurately formed regardless of the curved shape of the base member. Furthermore, the frequency characteristic itself is made flat for the base material using wooden pulp or the like for the major component and the electroacoustic transducing function is improved.

    • PURPOSE:To form a pattern having specific brightness or design effect on a transparent base material by forming a coated film of a surface treating agent prepd. by adding fluorescent dyes which emit fluorescence of visible light wavelengths and have light capturing performance to a coating material on the surface of the base material. CONSTITUTION:The surface treating agent prepd. by adding >=1 kinds of the fluorescent dyes which emit the fluorescence of visible light wavelengths and have the light capturing performance to the coating is coated on the surface of the transparent base material so as to have 2-200mu dry film thickness. The coated film obtd. in such a manner is dried and cured. The above-mentioned fluorescent dyes are added to the coating material at 0.01-5pts.wt. per 100pts. wt. said material. As a result, the desired fluorescence which is increased in density is released and the pattern having the specific brightness or design effect on the base material is formed on the base material. Such material is, therefore, adequate for use in ornamentation of glass and plastic moldings, road signs, etc.
