one oi which is very rast and will, upon beiner photorraphically exposed, developed and placed under a strong light-ray, produce a visible irnase upon the other emulsion without iurther subjecting the saine to any hind oi developing solution, and a further object oi' the invention is to provide a novel means tor combining such eleinents.
The Figure l is a cross-section oi a substantially transparent base i haviner upon one side i a negative emulsion t and upon the side t a coatine oi printing-out emulsion il covered by a waterprooa l; Fiaure 2 is a cross-section oi a substantially transparent base l' havin@ on the side fi negative material t' andon the side il' printing-out paper il covered by a waterproonng ll'; Figure 3 is a cross-section oi neuative material il" and printing-out paper t" with plastic layer l between, the outer suri'ace oi printing-out paper t having the waterprooiine 'l"; Figure t is a cross-section oi plastic base i'" having on its outer side t'" a neaative ernulsion t'" and upon its side t'" printina-out emulsion lim; Figure 5 is a perspective oi neuative material and printing-out paper marginally cemented, one to the other, one corner beine turned down; and Figure o is an end view oi negative material and printing-out paper physically distinct, one from the other.
lit is apparently. old in the art to provide comprisinp certain layers oi structure, includina a dissoluble coating removable by a hot hathV beiore subjecting the positive to a developinp solution, but the improvement about to be er.- piained provides a nini havina a base between layers of sensitized emulsion oi such distinct chters that, upon a photographic eosure ed, but has a more broad application to the art oi photography, its application beine limited only by the scope ot what hereinafter may be claimed.
Referring more particularly to the drawings, the Figure 1 illustrates a transparent or opal base i having upon its side t a hlm or negative inaterial t or having a coating oi negative emulsion upon the outer side il, the base l havingy upon its opposite side t a coating oi printing-out emulsion t the bach oi which is covered by a waterprooiina element l. The Figure Ziilustrates a transparenter opal base l having upon its side A t a nini or negative material t' or having a coatinp oi nepative emulsion upon the outer side il',
the base i' having upon its opposite side il printinu-out paper t', the baci: oi which is covered by a waterproofing element l. In usino' opal base, illustrated by the Fieures l and 2, it has -been discovered that, alter nialrina the first-er;-
posure on the negative emulsion coated side oi the iilrn and, while protecting the reverse side oi the layers, subject the erposed side to developine and tiring solutions, the printinn-out emulsion, by subjecting the exposed side ci the layers to a strong actinic light-ray, forms a positive image oi the subject already photouraphed whereby the operator or other individual may see the immediate and positive irnaee oi the sub- `lect without dissolving the negative layer as shown to be necessary in the previous art. The Fleure 3 illustrates a hlrn or negative teriai t" with a coating oi negative emulsion at il" and printing-out paper t" with a plastic layer l" therebetween, the baclr oi the printing-out paper havina the waterproofing covering ll". rii'he Fieure il illustrates a plastic base i" having upon its side t" a illm or negative material il" or having a coatingr oinegative emulsion upon the outer side ll'", the base l'" having upon its opposite side t'" printing-out emulsion or paper t'". lin using the plastic base, illustrated by the Figures Il and li, the layers may be pulled apart without ruining either layer and the prooi-print thus removed so that duplicate prints may be made from the negative. i course the wellirnown method oi optical printing system could be used with redected liebt and then the prooi emulsion would not have to be removed trom the layers in makina duplicate prints. llilaen the process or developing the negative element is by spraying the negative emulsion coated side oi. the nlm the waterproof element may be omitted in the manu-lecture oi the improved hiru as illustrated by the Figure d. illustrate a negative material tm' and printinuout paper tm adapted to be cemented one to the other. The Figure 5 iurther illustrates the niarginal cement layer i"" marginally securing the layers tm and tm one to the other along each of the iour edges. To provide a close contact between these layers within the uncemented area a vacuum may he establed therebetween in The Figures 5 and o any known manner, or the improved film may be placed upon a cylinder during the printing process, the layers 3" and 6" in conforming to the cylindrical surface conforming one to the other in relative close contact. To separate the marginally cemented layers such cemented marginal portions may be cut away, but, if the negative material be in plate form, the layers must be pulled apart. The Figure 6 illustrates two physically distinct bases 3 and 6 one of which is provided with a coating of negative emulsion upon its surface I"" and the other base is printing-out paper or is coated with printing-out emulsion as at 8, the distinct bases 3" and 6"" being adapted to be cemented/ one to the other marginally or otherwise before printing.
In using the improved quick proof process film, the film is first photographically exposed in the usual manner, the side of the film having the coating of negative emulsion having been exposed thereby to the subject the image of which subject is then developed upon the film by the usual developing and fixing process, but when, after such developing, the film is exposed to a 'strong actinic light-ray by means of which the negative image, as developed upon the film, is printed upon the printing-out paper or emulsion thereby producing a proof print without subjecting the printing-out paper or emulsion to any kind of developing solution. This improved method is especially adapted, but not limited, to be used in portrait work in connection with automatic photographic and developing apparatus so that a photographer, after taking a picture of a subject, may develop and fix the negative andthen, by merely subjectingl the improved film to a light, be enabled to show the proof within a very few minutes without destroying the negative. The improved method therefore has distinct advantages over methods disclosed by the previous art which shows that the negative is necessarily destroyed before the picture is made. In the portrait field the negatives are more important after seeing the proof; for the negatives are required in making duplicates pictures. Further advantages, other than the saving of time and preserving the negatives, are gained by the use of the improved film by reason of the fact that the subject may almost immediately see the result of his posing before the camera and thus substantially reduce the number of required sittings usually made necessary in order that, when the proofs were ready to be seen, a selection therefrom might be had; for, until my invention and discovery, the posing subject had no means of knowing the immediate result of a particular sitting, without destroying the negative.
