Title:
TRANSPARENT-BEAD EMBEDDED TYPE RECURRENT REFLECTING FILM BODY
Document Type and Number:
Japanese Patent JPS628102
Kind Code:
A
Abstract:

PURPOSE: To facilitate manufacturing work and to color a transparent film before and after the manufacturing work according to the possibility of the coloring by making the back pat of a transparent bead adjoin to a reflecting film and covering the front part of the transparent bead with the transparent film which substantially equal thickness.

CONSTITUTION: A recurrent reflecting film body reflects light incident through an air layer recurrently to the air layer through the refraction of the boundary surface between the air layer and transparent film 12, the refraction of the boundary surface between the transparent film 12 and the front surface of the transparent bead 10, the equal-angle reflection of the boundary surface between the rear surface of the transparent bead 10 and the reflecting film 14, the refraction of the boundary surface between the front surface of the transparent bead 10 and transparent film 12, and the refraction of the boundary surface between the transparent film 12 and air layer. Consequently, the manufacturing work is facilitated and the coloring is possible both before and after the manufacture working.
