COMPLETE SPECIFICATION.
Improvements in the Production of Green and Blueish-green
Colouring Matters.
1, OLIVER IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the
County of London, Chartered Patent Agent, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to the production of green and blueish-green colouring
matters belonging to the class of such colouring matters described in the
Specification to Patent No. 12,796 of 1888, and consisting of the sulphonic
acids of:

may be condensed with meta-oxy-benzaldehyde in manner described in the
process I B of the Specification No. 12796 of 1888, the leuco sulphonic acids thus
produced being sulphonised in manner described in process III to leuco sulphonic
acids of solid blue colouring matters and these colouring matters being oxidised as
described in process IV of the Specification No. 12,796 of 1888.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The herein described process for the production of colouring matters by
(1) Producing, instead of the oxy-leuco bases enumerated in Claim 1 of the
Specification No 12 796 of 1888

leuco bases by substituting for the bases enumerated in Claim 1 (b) of the
said Specification.

or producing the sulphonic acids of these oxy-leuco bases employing in place
of the bases enumerated in the Claim (1) 6 of the said Specification the
sulphonic acids of mono-benzyl-aniline, mono-benzyl-orthotoluide or dibenzyl
aniline.
(2) Converting these leuco bases or these sulphonic acids in manner described
in Claim 3 of the Specification No. 12796 of 1888 into the leuco sulphonic
acids of fast acid colouring matters and
(3) Oxydising these leuco-sulphonic acids in manner described in Claim 4 of
the Specification No. 12,796 of 1888.
The colouring matters produced as above set forth.
