Embodiment 1

[0586]

[0587] Dissolve 3-HO-ABNO: 0.15g in DURANATE(TM) TSS-100: 2.85g. After dissolving the caprylic acid solution: 0.002 g of bismuth tris(2-ethylhexanoate) there, it stirred at 45 degreeC under reduced pressure, and it was made to react for 2 hours. 3450 cm from the hydroxyl group of 3-HO-ABNO observed by FT-IR -1 The disappearance of the peak was used to confirm the reaction between the hydroxyl group of 3-HO-ABNO and the isocyanate group. Further add and mix DURANATE(TM)TSS-100: 12g to prepare 3-HO-ABNO masterbatch.

[0588]

[0589] Polymerizable monomer HLM101: 0.362 g, photopolymerization initiator HLI02: 0.0145 g were dissolved in DURANATE (TM) TSS-100: 3.69 g, and it was made A liquid.

[0590] In addition, PRAXCELL PCL-205U (polycaprolactone diol (molecular weight 530)): 2.42g and PRAXCELL PCL-305 (polycaprolactone triol (molecular weight 550)): 1.04g were mixed (PRAXCELL PCL-205U: PRAXCELL PCL -305=70:30 (weight ratio)), octanoic acid solution in which bis...

Embodiment 2～4

[0595] Except that the 3-HO-ABNO masterbatch was mixed so that the content molar ratio of 3-HO-ABNO and the photopolymerization initiator of component (d) was the value shown in Table 1, it was carried out in the same manner as in Example 1. The composition for holographic recording media and the sample for evaluation of the composition for holographic recording media were produced.

Embodiment 5～8

[0597] Use 5-HO-AZADO instead of 3-HO-ABNO, and make the 5-HO-AZADO masterbatch so that the content molar ratio of 5-HO-AZADO and the photopolymerization initiator of component (d) is the value shown in Table 1. The composition for holographic recording media and the sample for evaluation of the composition for holographic recording media were produced similarly to Example 1 except having mixed it.

Abstract

A composition for a hologram recording medium is provided, the composition containing a compound (e) having an isocyanate group or an isocyanate reactive functional group, and a nitroxyl radical group, the composition for a hologram recording medium being characterized in that component (e) contains component (e-1). Component (e-1): a compound having a complex bicyclo ring structure or a complex tricyclo ring structure in which the carbon atoms of the bicyclo ring structure or the tricyclo ring structure are replaced with a nitroxyl radical group.

Description

technical field [0001] The present invention relates to a composition for holographic recording media, a cured product for holographic recording media obtained by curing the composition for holographic recording media, and a holographic recording medium using the composition for holographic recording media. Background technique [0002] In order to further increase the capacity and density of optical recording media, holographic optical recording has been developed that records information in the form of holograms by changing the refractive index of the recording layer according to the light intensity distribution caused by light interference. medium. [0003] In recent years, studies have been conducted on the application of holographic recording media developed for memory applications to optical elements of AR glass light guide plates (for example, Patent Document 1). [0004] The higher the performance index M / # of the holographic recording medium is, the more preferable...
