FORGERY PREVENTING MEMBER, FORGERY PREVENTING SHEET, AND METHODS OF MANUFACTURING THE SAME

摘要

A method of manufacturing a forgery preventing member includes forming a first adhesive layer on one surface of a sheet substrate, forming a second adhesive layer on the other surface of the substrate, superimposing the substrate and a first water-soluble sheet or unsized paper with the first adhesive layer being sandwiched therebetween, superimposing the sheet substrate and a second water-soluble sheet or unsized paper with the second adhesive layer being sandwiched therebetween, and cutting or punching the substrate on which the adhesive layers are formed with the substrate being sandwiched between the first water-soluble sheet or unsized paper and the second water-soluble sheet or unsized paper.
