INFORMATION RECORDING BODY WITH LIGHT DIFFRACTING STRUCTURE, SHEET FOR LIGHT DIFFRACTING STRUCTURE STICKING, LIGHT DIFFRACTING STRUCTURE TRANSFER SHEET, AND MANUFACTURING METHOD FOR INFORMATION RECORDING BODY

摘要

PROBLEM TO BE SOLVED: To provide a light diffracting structure like a hologram seal which is capable of recording by irradiation with laser beam and then given complexity through the recording, and has transparency of its lower layer secured because of a transparent type. SOLUTION: On a card base material 2 or between card base materials 2b and 2a, the hologram seal 6 which has a peeling layer 62 a hologram layer 65, a transparent light-reflective layer 66, an infrared-ray absorbing layer 67, an adhesive layer 68, etc., laminated in order from above is laminated and the layer 67 has records formed with laser beam.
