Complete Specification for the invention entitled: COMPOSITE PHOTOGRAPHIC P~APE MnTERI L The following statement is a full description of this invention, including the best method of performing it known to me/us:-

44 0 0 0 a 0.0 o 0 4 o 00 04 o 0 o opo 0 0 0000o This invention relates to a composite photographic paper in rolls and a method of producing same. In particular it relates to the manufacture of photographic postcards.

In the past people have tried to develop methods of sending personalised postcards and this usually involves a costly and time consuming process of setting a printing plate and printing the postcard. The demand has developed for a postcard which is produced by normal photographic processes to allow ordinary photos to be developed as a normal postcard.

The back of ordinary photographic paper is not really suited to being a writing surface and any writing thereon is subject to fading and smudging.

At present, both in Japan and under the "KISS" system in Australia, Western Europe and a postcard may be created by way of rtamping a developed photograph with a rubber stamp or by hand cutting and pasting a postcard type label to the back of a developed photograph. This invention seeks to overcome the inefficiencies of labour and costs involved in these processes.

20 It is an object of the present invention to produce a composite photographic paper roll suitable for photographic development on one side and adapted to receive written indicia on the opposite side.

Accordingly, in one aspect the invention consists in a 25 composite photographic material comprising: a backing layer having a bond surface and a printing surface, the backing layer having indicia printed thereon and being suitable for writing thereon on at least the printing surface; and 30 a roll of unexposed photographic material having a photographic surface and a back surface, wherein the bond surface of the backing layer is bonded to the back surface of the photograph paper to form the composite photographic material and the strength of the bond is substantially unaffected by normal photographic development processes.

Preferably, the backing layer is of plastics material, metalised paper material or wood pulp paper material.

0000 a 00 a t 00 0 00 I I 3809S/JM 2 lA i Preferably, the bond is formed by the application of pressure.

Preferably, the backing layer is adapted to receive l printed indicia on both surfaces.

Preferably, the backing layer is translucent and the printed indicia is applied to the bond surface, protecting the printing from chemical attack during development of the photographic paper.

Preferably, the printed indicia is in the form of postcard markings.

In one form of the invention the baking layer may be coloured.

According to another aspect, the invention consists in a method of producing a composite photographic material comprising the steps of; printing indicia on a backing layer having a bond surface o and a printing surface suitable for writing thereon; o placing the back of a sheet of unexposed photographic 0Q material in contact with the bond surface of the backing layer under darkroom conditions and forming a bond therebetween, the o oo strength of the bond formed being substantially unaffected by o oo normal photographic development processes.

Preferably, the bond is formed between the backing layer and the photographic paper by applying pressure thereto.

25 One preferred embodiment of the invention will now be 0040 "o described by way of example only with reference to the o° accompanying drawings in which: o e Figure 1 shows a roll of the composite photographic paper S°in accordance with the present invention; 30 Figure 2 illustrates an example of postcard indicia Sprinted on the backing layer of the composite photographic 7, paper; Figure 3 shows a cross-sectional view through the composite photographic paper; Figure 4 is a digramatic illustration of the manufacture of the composite photographic paper; 3809S/JM 3 lr.4 1_ l i--i-U I i i aI r 9 IC It o t 00 0 o 0 o o o r 00 t1 9,9 Ir 6 P P Figure 5 shows a cross-sectional view through the backing layer of the composite photographic paper; and Figure 6 shows diagramatically apparatus for producing photographic postcards or the like using composite photographic material in accordance with the present invention.

Figure 1 shows a roll of the composite photographic paper A as would be delivered to a photo-developer for use in theirprinting process to produce personalised postcards from standard photographic films currently in use.

Figure 2 illustrates a type of printing 3 likely to appear on the backing layer 2 of the composite photographic paper. The print indicia is typical of postcards world wide and may contain variations as normally found in the trade or to comply with the protocol of various countries or companies.

The composite photographic paper A as shown in cross-section in Figure 3 comprises a layer of normal photographic paper 1 mounted to a backing layer 2. The process of mounting the photographic paper to the backing layer may be produced by either of the following methods.

In the first method, a pressure sensitive adhesive is applied to one side, the bond surface, of the backing layer and a protective film is applied over it. The other side, the printing surface, is then printed with a fast drying ink with the required postcard markings. The backing layer is then passed through a laminating machine which removes the protective layer and applies the backing layer to the back of standard non-exposed colour photographic paper under dark room conditions to form the composite photographic material.

In a second method, the backing layer is first printed 30 with the required postcard markings with fast drying ink on either the bond or the printing surface. Then, under strict dark room conditions the pressure sensitive adhesive is applied to the bond surface of the backing layer and the standard photographic paper is laminated to the backing layer in a one line operation to produce the composite photographic paper.

A roll of photographic paper 1 and a roll of backing layer 2 is fed between pinchrollers 4 and 5 such that the bond surface of the backing layer is adjacent the 5 back of the photographic paper i. The pressure applied to the two layers as they pass between rollers 4 and 5 bond the two together to form the composite photographic paper A which is then formed into a roll for storage and transportation. The operation of bonding the backing layer to the photographic paper must be carried out under dark room conditions to avoid exposure of the photographic paper.

The backing layer of the first method as illustrated in Figure 5 comprises the backing layer 2, a layer of pressure sensititve adhesive 6 and a protective film 7 which is removed before the backing layer is bonded to the photographic paper.

The roll of composite photographic paper A is used in a standard photo developing machine and illustrated in Figure 6. The composite photographic paper is fed into the printing section 8 wherein the individual photos are developed on the 20 composite paper. After development, the developed photos still attached in a continuous length are fed to a cutting facility 9 wherein the paper is automatically cut into individual personalised postcards in a one step process, without requiring hand processing or printing after being cut.

The rolls of composite paper A would normally be any size required to comply with non-exposed photographic paper roll lengths. The use of the composite photographic paper would enable the production of individual postcards for all photos at the time of developing or as many postcards as are required 30 from any individual negative either at initial processing or at some later stage. The customer can choose to have his negatives processed in either the normal way or with the composite photographic paper or a combination of both. There is no additional procedure required at the developing/processing stage.

An instant personalised postcard is produced which only requires a message and a postage stamp to be mailed anywhere in the world.
