What is the spectral response of Brilliant Blue FCF?

[Athiril]

This chemical here - http://en.wikipedia.org/wiki/Brilliant_Blue_FCFCan anyone tell me it's spectral response?

Specifically I was interested if this dye aborbs energy in the 700nm to 1600nm range of light.I know it says it has a cut-off for 628nm, but that is for the visible spectrum, many dyes/pigments have big spikes outside their visible cut off points, for example, cobalt blue and ultramarine pigments.

There's an absorption spectrum near the bottom:

but it only goes out to 750 nm.
