Abstract

410,224. Signs. BULMAN, W. J., McDermitt Street, Winnipeg, Canada. Aug. 23, 1933, No. 33651/32. Drawings to Specification. [Class 3 (ii).] A non-photographic negative or diapositive of sharp outline is produced by making an original design, in water colour, asphaltum or printing ink, upon a sheet of celluloid or transparent material coated with collodion or celluloid, drying, covering the whole surface with a medium comprising amyl acetate and a suitable aniline dye cut in methyl alcohol, and finally washing in water or other liquid capable of removing the original design and the overlying colour. The negative of the original design so obtained may be used as a transparency or a screen for illuminated signs &c.
