Correction 1984. 6.2t - The scope of claims for utility model registration shall be amended as follows. O Utility Model Registration Claims In a retroreflective sheet-like article consisting of a large number of transparent microspheres embedded in a transparent resin, a focusing resin layer, and a light reflecting layer, the back surface of the top surface of the transparent microspheres is The light reflecting layer is located closer to the transparent microspheres than the focal point of the transparent microspheres,
and a retroreflective sheet-like material in which a light reflecting layer on the side and back surfaces of the transparent microspheres is at a focal point.

Claims

[Scope of utility model registration request]

In a retroreflective sheet-like product consisting of a large number of transparent microspheres embedded in a transparent resin, a focusing resin layer, and a light reflecting layer, the light reflecting layer on the back surface of the top surface of the transparent microspheres is a transparent microspheres. A retroreflective sheet-like article which is located closer to a transparent microsphere than the focal point of the child, and in which a light reflecting layer on the side and back surface of the transparent microsphere is at the focal position.
