較べ、簡便さ・及び迅速性という利点を有している。(B) Prior art and its problems A lithographic printing material using the DTR method, specifically, a method in which at least one photosensitive layer is provided on a support, and an image photosensitively recorded on the photosensitive layer is reversed and transferred onto the support. By imagewise exposing a material consisting of a layer of physical development nuclei to light and subjecting it to a silver diffusion transfer development process to form a metallic silver image on the external surface of the material (the lithographic printing material to be produced is directly produced) - Compared to the conventional lithographic printing material (PS plate), which is called a plate-making method and is characterized by the use of lithographic film as an intermediate process, it has the advantage of simplicity and speed.

ラーなどの像反転機構を内蔵した専用の製版カメラで、
囮影から製版処理まで自動的に行われている。Lithographic printing materials using the TR method are manufactured using a special plate-making camera equipped with a built-in image reversal mechanism such as a prism or reflective mirror to prevent the original image from becoming a left-right reversed image.
Everything from decoy shadowing to plate-making processing is done automatically.
この様な製版カメラは、高価であるだ（プでなく、像反
転機構により像の解像性・鮮鋭度を低下させるという欠
点がある。Such a plate-making camera is not only expensive, but also has the disadvantage that the image reversal mechanism reduces image resolution and sharpness.

書に於ては、この露光方法を裏焼きという。In order to obtain a lithographic printing plate with a normal image using a plate-making camera that does not have an image reversal mechanism, as described in Japanese Patent Application Laid-Open No. 48-89007, it is necessary to Methods for imagewise exposure of original documents are known. In this specification, this exposure method is referred to as reverse printing.

増強せしめる事が要求され、各種改良がされてきた。On the other hand, lithographic printing materials using the DTR method have insufficient resistance to mechanical abrasion, resulting in the loss of hydrophobic areas that carry ink images or gradual loss of ink receptivity. It has the disadvantage of a decrease in printing durability. Hydrophilic areas gradually become hydrophobic due to mechanical abrasion, and non-printing areas become smeared with ink, and hydrophobic areas become uniformly receptive to oily inks. defects, which cause variations in ink receptivity in the image area;
This prevents the area being printed from receiving a uniform amount of ink. As with other planographic printing plates, it is necessary to increase the printing durability of planographic printing materials using the DTR method by adjusting the composition of the plate material, the composition of the processing liquid, printing conditions, etc. Various improvements have been made.

6548 etc., the printability has been significantly improved. In particular, the addition of 2 to 10 μm of a matting agent such as silica, clay, talc, gicrite, or rice starch to the lower te as taught in JP-A-55-100554 and JP-A-58-196548,
It improves the water retention of the plate surface and significantly improves printing durability, and is therefore important in lithographic printing materials using the DTR method.

鮮鋭度を低下させるものである。However, during back printing, the undercoat layer containing a matting agent exists in the optical path on the plate-making camera from the original to the photosensitive layer, and there are differences in the refractive index between the binder and the matting agent, etc. It strongly diffuses light and improves resolution and
This reduces sharpness.

イラジェーション防止剤と呼ぶ。Various antihalation agents and antiirradiation agents are known to improve resolution and sharpness when exposure is performed from the surface (emulsion surface). Usually, it is called an antihalation agent when used in an undercoat layer or an undercoat layer, or an anti-irradiation agent when used in an emulsion layer.

た。Japanese Patent Publication No. 60-25777 discloses a graphic art photographic material for reverse printing using the DTR method. This specification shows that high resolution and high sharpness can be obtained by using the undercoat layer as an antihalation layer having an optical density of 0°9 or less. However, when the undercoat layer containing the above-mentioned matting agent is used as an antihalation layer, the photographic properties become softer in reverse printing, and sufficient resolution and sharpness cannot be obtained in reverse printing. Ta.

（主に前方散乱）が起こる事が原因と推測される。This softening of photographic properties during back-printing is unlikely to occur in the absence of a matting agent, and may be due to some interaction between the matting agent and the antihalation agent (usually carbon black), for example, the surface of the matting agent. The cause is presumed to be that aggregates are formed due to the aggregation of the antihalation agent, and light scattering (mainly forward scattering) occurs there.

を大きく低下させるものである。The softening of the photographic properties of lithographic printing plates using the DTR method not only reduces the resolution and sharpness mentioned above, but also reduces the printing durability of fine lines and halftone dots, and also makes it difficult to use them in pasted manuscripts. In this case, the pasting marks are recorded on the printing plate, which is a serious problem and greatly reduces the performance of the lithographic printing plate.
