A light reflection material comprises transparent body of organic glass having therein a thin through hole or holes whose inner wall is smooth. This material is useful for an ornamental material, a lighting material, eye-obstructing material, shading material, etc. This material is manufactured by pouring a raw material into a mold within which a thread or threads of synthetic fiber are straightly or curvedly set according to aimed pattern and pulling the thread or threads out of the formed body to form a thin hole or holes or pulling the thread or threads to separate them from the inner wall of the hole or holes. As a result of it, a hole or holes of a shape and number corresponding to those of the thread or threads are formed in the formed body. |

DETAILED DESCRIPTION It is an object of this invention to provide a new light reflection material which is excellent for an ornamental signboard, a display, an ornament, a shading material, an eye-obstructing material, etc.
of the original three-dimensional effect, besides a thin illumination material for which the edge-lighting is used.
To achieve the above-mentioned object, the present invention provides a light reflection material comprising a transparent body made of an organic glass having one or more thin through holes penetrating said body and being smooth on inner wall thereof.
Further the present invention provides a method for manufacture of the above light reflection material comprising setting a thread within a mold, pouring a liquid organic glass material into said mold, polymerizing and hardening it at a temperature higher than the temperature at which the thread causes thermal shrinkage, taking the polymerized and hardened organic glass from the mold, and then pulling out or separating the thread from the glass.
