Definitions
- the present invention relates to an im- 5,
- the sensitive layers themselves are colored with an-inactive coloring material which can be eliminated when washing the proof, this coloring'm'aterial being ored screens being applied on each of the emulsions to permit of their exposure and printing with light.
- the film forming the subject matter of the invention is composed of two layers of positive emulsion b--c separated from each-other by a thin transparent layer a.
- These layers b0- present this essential particularity that it will be impregnated with an inactinic colouring material.
- the colcuring materials for that purpose may be derivatives of anilin, they must-have a high dyeing power for gelatin, have no action onthe sensitiveness of the silver salt and they must be automatically eliminated by simple washing in pure water, such for instance as tartrazine. H
- the two elements of the double sensitive layer can be dyed in two diflerent iilactinic colours, one of the elements in yellow for instance, the other inorange or in reen.
- the photographic images are obtained on the double sensitive layer by a single de velopment.
- the duration of the development will vary according at it is desired to obtain a proof visible by reflection or a proof adapted to be projected or examined by transparency.
- the development will be stopped as soon as the black image will appear by reflection in all its details, on the contrary it will be carried out to the fullest extent in the second case.
- the proo obtained may be caused to adhere on any support, wood, ivory, metal, porcelain, etc.
