PRINT MATERIAL FOR COPY PROTECTION

PROBLEM TO BE SOLVED: To provide a print material for copy protection suppressing discomfort such as gloss and glare on the surface of a script printed with a toner, eliminating deterioration in visibility and readability of characters and patterns on the script, and, in a transcript obtained by copying printed document information by a copying machine, having characteristics of preventing interpretation of a content of the document information, thereby surely preventing leakage of the information to the outside.SOLUTION: A print material for copy protection is a copy material for use in toner printing formed by sequentially providing a black layer, a multilayer laminate film layer, and a polyethylene terephthalate film layer. The black layer has a reflecting density (OD value) of 1.30 or more. The multilayer laminate film layer has a unique hue due to structural coloring using multiple enhanced reflection of specific wavelength by optical path difference interference ((refractive index)×(thickness)) of each layer and has a peculiar design property in which reflection color is changed when viewed from different angles.
