った。2. Description of the Related Art Conventionally, there is no suitable plate material for laser engraving printing, and it has been proposed that carbon black is mixed with polyethylene to form a sheet. However, in order to make the surface uneven, Since high energy is required and it is industrially difficult to obtain a smooth surface as a printing plate material, there has been no one that has been put to practical use so far.
【０００３】一方、感度を高めるために、ニトロセルロ

とするものである。The problem to be solved by the present invention is to provide a printing plate material that can be drawn on the surface even with low laser energy, has a smooth surface, and is less likely to cause scumming in printing.

等の架橋剤を加えることもできる。The photosensitive layer of the present invention comprises nitrocellulose, carbon black, and polyester resin. Nitrocellulose has a nitrogen content of 10 to 14% and various degrees of polymerization, but the nitrogen content is 11.5-12.2. %, Solution viscosity 1-1
/ 8 seconds are preferable, and if necessary, two or more kinds may be blended. In addition to classification by ASTM, there are various types of carbon black such as those for color, rubber, and dry battery depending on the use, and any of them can be used as long as they are stable in composition. Further, in order to facilitate dispersion, color chips and color pastes in which carbon black is previously dispersed in nitrocellulose are commercially available, and these can also be used. Although there are various polyester resins, aromatic polyester having excellent solvent resistance and abrasion resistance is preferable. Further, a crosslinking agent such as a melamine resin can be added to the photosensitive layer, if necessary.

【発明の効果】感光層の熱分解性が高いので低いレーザ
ーエネルギーで表面に凹凸を付けることが可能となる。EFFECTS OF THE INVENTION Since the photosensitive layer has a high thermal decomposability, it is possible to make unevenness on the surface with low laser energy.
【０００９】表面が平滑なため、ブレードでのインクの
掻き取りが十分行われ、印刷物の地汚れが発生し難い。Since the surface is smooth, the ink is sufficiently scraped off by the blade, and the background stain of the printed matter is hard to occur.
