LAMINATED MATERIAL WITH IMPRINTED INFORMATION, ARTICLE ON WHICH THE SAME IS ATTACHED, METHOD FOR READING INFORMATION CODE |
摘要 |
<p>It is an object of the present invention to provide a laminated member with an recorded information code, having a high reading accuracy, which do not detract from product design and which do not require a special reading apparatus. A laminated member 10 of the present invention comprises a transparent material layer 12 on which an information code is recorded, and a reflection-reduction layer 14 provided at the opposite side from a side where the information code is observed. The transparent layer 12 comprises low-reflectance portions 18 and high-reflectance portions 16 having a higher reflectance than the low-reflectance portions 18. The information code is recorded as a distributed pattern of the high-reflectance portions 16. The reflection-reduction layer 14 reduces reflected light advancing to the transparent material layer 12.</p> |
