Abstract
PURPOSE:To obtain a reflector which has a smooth surface and is excellent in the reccurrent reflection, by using a laminated matter obtained by attaching the transparent glass balls to a sheet-type matter containing a sepcific tackiness agent layer and then coating a specific binder on the glass balls. CONSTITUTION:A tackiness agent layer 1 having the low tacky strength to inorganic glass balls (grain size: about 30-150mu) is formed to a sheet-type matter 2, and then transparent glass balls 3 and 3' are scattered on the layer 1 to obtain a recurrent reflective layer A (in which the transparent glass balls are burried into the layer 1 only at a part of them). Then a binder 4 (such as paste-type mortar cement) that shows higher tacky force to the glass balls than the above-mentioned tackiness and is not fixed to the tackiness agent is applied on the layer A. Thus the layer A is fixed tightly to the binder 4. Thereafter, the sheet matter 2 is removed along with the layer 1 to expose the layer A composed of the balls 3 and 3' which are fixed by the binder 4 on the surface. Thus a transferring type recurrent reflector is obtained.
