    摘要： When laser beams with a wavelength of 9.3 nullm or 9.6 nullm are used, a pulse width t (nullsec) which is a radiation time of the laser beam and an energy density E (kw/cm2) of the laser beam on an X-ray film are set such that they meet requirements based on an area A between line segments A1 and A2. Moreover, when laser beams with a wavelength of a 10-micrometer band, such as 10.6 nullm, is used, the pulse width and the energy density are set such that they meet requirements based on an area B between line segments B1 and B2. As a result, since the pulse width t is within a range of equal to or larger than 3 nullsec and smaller than 30 nullsec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.

    摘要： By irradiating a laser beam onto an X-ray film that includes a support layer having disposed thereon an emulsion layer, the emulsion layer is melted, numerous minute air bubbles are generated in the emulsion layer, and the emulsion layer becomes convex, whereby a visible dot pattern is formed. The irradiation time and wavelength of the laser beam are selected so that separation is not generated between the support layer and the emulsion layer. By defocusing and irradiating the laser beam, the X-ray film may substantially uniformly receives energy of the laser beam. Moreover, an undersurface layer may also be formed, and the laser beam may be irradiated onto the undersurface layer to form a dot pattern on the undersurface layer. A device and a method for forming a marking pattern representing identification information on a rolled photosensitive material and cutting the photosensitive material into sheets are disclosed.

    摘要： A photosensitive material in which a fog unnecessary for a photosensitive material is not generated when irradiation of a laser beam and a character or a mark is printed by an array of optically distinguishable dot patterns is provided. When the dot patterns are arrayed by M number in column and N number in row and the character or the mark having a size of AnullB is printed, the dot pattern has irregularity of no more than Snull10 nullm, and an almost circular shape of no lower than 100 nullm and not more than the smaller diameter either A/M or B/N, when viewed from the emulsion layer side. A surface roughness is set in the range of 0.2 nullm to 1.0 nullm.
