Definitions
- This invention relates to matrix film for the production of colored copies.
- the matrix films which are destined for the I production of printing reliefs are generally .exposed through the emulsion carrier, developed with a hardening developer and washed out in warm water, so that after the washing process a relief'remains on those places only, where silver was present.
- the relief may be also obtained by developing with an ordinary developer and after treating with bichromate. However, without special precautions the relief becomes too high and the gradation consequently too steep. In order to prevent this, there is ordinarily added to the emulsion layer a yellow or red dyestufi' ..vide a method for the preparation of colored reproductions with the aid of matrix films.
- the matrix films hitherto known were destined to be exposed under black and white originals and consequently they were not specially sensitized.
- the new material on the other hand is designed for obtaining the three. separation pictures from the colored originals directly on the matrix film.
- the emulsion is dyed with a black dyestuff in a suitable density.
- the emulsion carrier also is tinged with a neutral gray dyestufi in such a manner, that it possesses a transparency of about 70%. In this way one avoids the halation by reflection which always happens, when a film is exposed through the emulsion carrier.
- the film is sensitized for green and red light, while insuring that the sensitizing maxima in the green and in the red correspond as much as possible to the absorption maxima of the purremoved either by the treating baths or by a special bath.
- colloidal silver may be added to the emulsion in place of the black dyestufi. This, however, is not possible, when films are afterwards hardened with the aid of bichromate, sinceunder these circumstances the silver added to the emulsion would harden the entire emulsion layer.
- Red separation picture --Emulsion red sensitized and'dyed with a red absorbing dyestuil, for instance blue-green.
- Antihalation layer which must be located between the emulsion layer and the original, for instance, between the carrier and the emulsion or nn'the non-emulsified side of the film.
- the copying must be done with a point-light source, in order to insure sharpness in spite of the distance between original and copying material. Another possibility is to copy (enlarge) optically.
- dyestuffs are to be used which are easily dissolved or destroyed in the treating baths. Naturally also such dyestuffs can be. employed which have tobe destroyed by a special bath.
- trix films each comprising an emulsion carrier I and a single photographic emulsion layer thereon which is panchromatically sensitized and contains a readily removable from gray to black fllter dyestufl to the different primary color lights 1 proceeding directly from three-color separation originals and processing the-exposed films in the manner usual with matrix film.
- each matrix film contains as an antihalation agent a neutral gray dy estun.
