Well, the complicated part is that I'm trying to set it up so that it deflagrates spontaneously, ideally after being exposed to light and air for a
brief period. Perhaps soaking the middle of one sheet with potassium permanganate solution or adding a tiny drop of red fuming nitric acid? I was
under the impression that there was a method for producing time-delayed ignition of paper using nitric acid, but I never learned how to control it...

Make a small patch on the book made of potassium chlorate and sugar and touch it with a drop of sulfuric acid.

Wow - Your mention of a scroll just made it all possible in a reusable manner - And all the ignition parts are abailable at radioshack for under
$10...
The central rod of your scroll has a 555 in one-shot mode, the trigger being a phototransistor and the delay being 30 seconds or so - The load is
connected to a model-rocket style ignitor and the battery is an SOCl2 cell - If you've got a lathe or can handle a drill like a jedi you can fit the
entire circuit in a 1/2" (or maybe smaller) dowel... One corner of the scroll is tapered out in such a way that the light sensor is exposed and trips
the timer as soon as it is unraveled...
As for the paper, I would go for a fine, tight-knit but thin cloth and dope it heavily in NC lacquer - You'd have a continuous sheet with some
stability to it, which would easily catch flame on ignition - As a plus, the virgin fabric should smolder in a random for some time and give it that
extra hellish vibe.
...Just a thought... You could have a LOT of fun with something like that if you know the right people...
If you see me running, try to keep up.

In the USA there were many of the Super Fund clean-ups of various polluter and paper mills were one of the notorious ones. TTBoMK there are a great
deal of additives in common linen, bond, and pulp paper. I don't have the facts at my finger-tips however the level of additives are fairly
significant. I can find some of the chemicals used to make paper "adhere as a fibrous flat material" but in all likelihood it's would vary with the
type. Some background on Monroe's experiments with NC lead me to believe that in order to get a nitration to 12+ % one must have a fairly pure
precursor.
As an overall concept of "energetic paper" using the "type face" as the energetic (let's say NG) one also has the complication of how to apply the
energetic ink. Common plate printing, an "ink-jet" style or a laser style would be a risk that would exceed the boundaries of any safety level even IF
some form of "pure" cellulose-form paper could be developed. Just as an intellectual exercise, this is no small task.

I tried it yesterday. Immersed a piece of nitrocellulose paper in a few ml of the water that is used to keep the trinitrophenol wet during storage,
which should therefore be saturated at room temp.
The nitrocellulose paper turned bright yellow as it was wetted by the TNP solution. (it doesn't soak up large quantities, however, as it does not
appear to be very fibrous like regular paper). When I took it out after half an hour, I could not observe any differences except for the color. It was
still flexible, perhaps a bit more than in a dry state. Upon drying, the yellow color turned much fainter. When completely dry, the paper was still
noticeably yellow, but a lot less than before. I lit it and it burned at pretty much the same rate as before (which is pretty quick), leaving no
residue or smoke.

Interesting. Most interesting.
Enthusiastic thanks for your contribution!
