For the infra-red transmission (to 12/x) and reflection powers of a number of aniline dyes, see Johnson and Spence, 

 Phys. Rev. 5, p. 349, 1915. 



Scientific Paper 440 of the Bureau of Standards, 1922, gives spectrum transmission curves (0.24 to 1.36 /ii) for the 

 following dyes. Napthol Yellow S, Orange I, Amaranth, Erythrosine, Indigo Disulpho Acid, Ponceau 3R, and Light 

 Green S F Yellowish.
