Abstract:
1. A volume hologram transfer oil comprising: a base material; a protective layer formed on the base material; a volume hologram layer formed on the protective layer and having a volume hologram recorded; and a heat seal layer formed on the volume hologram layer, wherein the protective layer contains a hard coat component, a rupture elongation control component and a foil cutting characteristic control component, the hard coat component includes an ionizing radiation-curable resin obtained by polymerizing a raw material composition which has, as its major component, an oligomer, having a radically polymerizable active group, the rupture elongation control component improves a rupture elongation of the protective layer compare to a case when the protective layer is formed only of the hard coat component, and is an ionizing radiation-curable resin obtained by polymerizing a raw material composition which has, as its major component, an oligomer having the radically polymerizable active group, the number of the radically polymerizable active groups of the oligomer which is the raw material composition of the rupture elongation control component is less than number of the radically polymerizable active groups of the oligomer which is the raw material composition of the hard coat component, a molecular weight of the oligomer which is the raw material composition of the rupture elongation control component is larger than a molecular weight of the oligomer which is the raw material composition of the hard coat component, the foil cutting characteristic control component has a thermal expansion coefficient different from those of the hard coat component and the rupture elongation control component, the foil cutting characteristic control component is incompatible with the two components and is dispersed in the form of microparticles in the hard coat component and the rupture elongation control component, and the protective layer is formed by irradiating an ionizing radiation to a coating film of a protective layer-forming coating solution which contains the raw material composition of the hard coat component, the raw material composition of the rupture elongation control component and the foil cutting characteristic control component.
