PROBLEM TO BE SOLVED: To provide a method for forming a high refractive index pattern typified by a hologram in an easy process, a composition for forming a high refractive index pattern relating to the above method, and a laminate having a refractive pattern formed therein by using the composition.SOLUTION: The laminate comprises a substrate and a photosensitive layer that is deposited on the substrate and contains metal oxide nanoparticles surface-modified with a compound having a photopolymerizable reactive group, a photopolymerizable compound, and a photopolymerization initiator. The photosensitive layer has a refractive index pattern formed therein including a first region and a second region, in which the first region has a higher percentage of the metal oxide nanoparticles than in the second region.SELECTED DRAWING: Figure 2 |
