摘要

The disclosed method and device for rapidly analysing cross-link density enable the easy and accurate measurement of cross-link density in the lamination process. An object (1A) to be tested is prepared by sandwiching a sheet for measuring cross-link density between a transparent substrate and a rear surface material. The object (1A) to be tested is placed in a lamination means (100) and lamination is implemented. The object (1A) to be tested is taken out from the lamination means (100), the transparent substrate and rear surface material are detached from the sheet for measuring cross-link density, and the sheet for measuring cross-link density is removed. A reference point and at least one comparison point on the sheet for measuring cross-link density are chosen and the cross-link density of the points is measured. The sheet for measuring cross-link density exhibits a cross-linking reaction by lamination and bonds with neither the transparent substrate nor the rear surface material by the cross-linking reaction.
