n,?-Conjugation in N-methylvinylamine. A photoelectron spectroscopic study

The unstable species N-methylvinylamine was prepared by the thermal decomposition of gaseous 2-methylaziridine in a flow system its UV photoelectron spectrum was recorded.The first two bands were observed at 8.00 and 11.00 eV.The methyl substituent shows the effect of reducing the degree of conjugation between the nN and ?CC orbitals, as revealed by a comparison with the spectrum of the parent compound vinylamine.

Water-soluble fast polymeric black colorant, its preparation and use in dyes and inks

A family of polymeric black colorants is disclosed. The subject colorants are composed of an organic polymer backbone comprised of a plurality of aromatic rings from which depend via azo groups a plurality of chromophore units having the structure STR1 wherein M is hydrogen or preferably a cation. These polymeric colorants are water-soluble, and noncrystalline and form dyes and inks that are fast to paper stock.

Polymeric aminoanthrapyridine orange colors

Polymeric orange colors are disclosed having a noncrosslinked organic polymer backbone to which is covalently bonded a plurality of chromophores having a particular anthrapyridine structure. The colors are represented structurally as STR1 wherein R1 and R2 are independently selected from among hydrogen, halos, lower alkyls, lower alkoxies, nitros, and sulfonates; R3 is selected from hydrogen, alkyls and alkylsulfonates; R5 is a lower alkyl or lower alkyl sulfonate and R4 is a noncrosslinked organic polymer linking a plurality (k) of said anthrapyridines into a polymeric colorant. The polymeric colorants are especially useful as nonabsorbable orange colorants for edibles.
