A general-use white color reflecting material, and a process for production thereof are provided. The white color reflecting material, without troublesome surface treatment such as formation of a reflective layer by plating, is capable of reflecting a near-ultraviolet ray of a wavelength region of 380 nm or longer or a near-infrared ray sufficiently without light leakage; does not become yellow even when exposed to near-ultraviolet rays; has excellent lightfastness, heat resistance, and weatherability; has high mechanical strength and chemical stability; is capable of maintaining a high degree of whiteness; and is easily moldable at a low cost. Further a white color reflecting material used as an ink composition for producing the white color reflecting material in a film shape is also provided. The white color reflecting material comprises; a silicone resin or silicone rubber formed from titanium oxide-containing silicone composition, in which anatase-type or rutile-type titanium oxide particles are dispersed.
