摘要:
The volume hologram recording photosensitive composition provided by the present invention contains at least a fluorine-contained photoreactive compound represented by the following formula (1): R1—R3—(CF2)n-R4—R2 wherein R1 and R2 are photoreactive groups which can be bonded to each other by photoreaction, and each of R3 and R4 is independently a single bond or a bivalent hydrocarbon group having 1 to 5 carbon atoms, and n is an integer of 1 or more. This volume hologram recording photosensitive composition is used to form a recording section of a recording medium, and then the section is exposed to light, whereby a bright volume hologram can be obtained.

The present invention provides a volume type hologram recording photosensitive composition. A type (i) composition comprises one or more photopolymerizable compounds, a heat-curable compound and a heat-curing crosslinking agent, wherein the heat-curing crosslinking agent is a latent heat-curing crosslinking agent which is not reacted in an interference exposure process, is not reacted at the heating temperature used in a refractive index-modulation promoting process and becomes active at the heating temperature used in a heat-curing process. A type (ii) composition further comprises a binder resin beside the type (i) volume type composition.
摘要:
There are provided a hologram laminate and a hologram label which do not involve any problem in the production process per se of forging preventive labels using a volume hologram, can provide a reliable process of the attainment of forgery preventive effect, and can make difficult to notice the signs of the forgery preventive processing. In applying a protective film 108 onto a hologram 107 through a second pressure-sensitive adhesive 109, the adhesive strength is partially varied. By virtue of this construction, upon separation of the protective film 108, the second pressure-sensitive adhesive 109 is partially left on the hologram 107, so that the fact of the separation can be found out.
