The chemistry of photography, particularly colour photography.
Like I said, that's a vast domain. You'll have better luck looking for more specific topics. Color couplers is a totally different ballgame from silver halide developers, which is yet again different from everything related to gelatin/peptides, which is different from bleaching & fixing...
Anyway, you might want to have a look here:

You'll notice Fujita was mentioned there, which is probably one of the more authoritative and recently modern texts on the subject. However, it pretty much takes a degree in chemistry to understand it.
A more accessible, pragmatic text might be
@laser / Bob Shanebrook's book.
The book you linked in your initial post (by David Rogers) sits somewhere in the middle between these two extremes of highly technical vs. highly accessible. I've had a brief look at it and I think it's as good as it gets if you're looking for something that hits the sweet spot and is comprehensive on the cluster of subjects involved. Further reading is easy to determine as your book lists references for the various topics.
I do not know how authoritative it is.
I'm not sure if that's a question of all that much concern. As an introductory text to the mechanisms and some of the main technological trajectories involved, it looks fine to me. For specific subjects, there are evidently better texts, but those will necessarily be more limited in scope, and will be a lot more challenging to read without a solid background in chemistry. On topics where you have doubts as to whether a particular topic discussed by Roger is done so in a representative way, it's a matter of pulling some academic articles on the topic to see what the various perspectives and nuances are. Qualifying the book as a whole as authoritative or not doesn't yield much of an insight; as a more broad, integrative view it'll always miss some of the nuances by necessity. I wouldn't worry about that unless you're in the business of creating color silver halide products of your own.
