摘要： A spool for a photographic film comprising 50 to 99.8 wt. % of polystyrene resin, 0.05 to 2.2 wt. % of dimethylpolysiloxane and/or modified dimethylpolysiloxane of which a part of methyl groups are substituted by carboxyalkyl groups, 0.5 to 6 wt. % of rubber and 0.05 to 3 wt. % of carbon black having a pH of 5 to 9 and a mean particle size of 10 to 120 m.mu., and the outer surface of the flange of the spool is made rough so that the reflectance of the incident light at an incident angle of 75 degrees is less than 40% in the direction of regular reflection at an angle of 75 degrees.Static frictional coefficient of this spool against metal is small, and thereby photographic film can be drawn out of a photographic film cartridge smoothly to the last. Breakage of the perforations of photographic film does not occur. The outer surface of the flange of the spool is not glossy and its reflectance is low. Accordingly, the light passed through the space between end cap of cartridge and boss of spool does not reach the photographic film in the cartridge.
摘要翻译：一种用于照相胶片的卷轴，包括50至99.8wt。聚苯乙烯树脂的％，0.05〜2.2重量％％的二甲基聚硅氧烷和/或其一部分甲基被羧基烷基取代的改性二甲基聚硅氧烷，0.5〜6重量％％的橡胶和0.05〜3wt。％的炭黑的pH为5〜9，平均粒径为10〜120μm，并且使卷轴的凸缘的外表面粗糙，入射角为75°的入射光的反射率度在75度的角度下的规则反射方向小于40％。该卷轴对金属的静摩擦系数很小，从而摄影胶片可以平滑地从摄影胶片盒中抽出到最后。摄影胶片穿孔不会发生破裂。阀芯法兰的外表面不光滑，反射率低。因此，通过墨盒的端盖和阀芯的凸台之间的空间的光不会到达墨盒中的照相胶片。

摘要： A magazine for a roll of a photosensitive strip material which comprises a core rotatably supporting the roll and a light-shielding container body admitting the core and having an opening for drawing out the photosensitive strip material and light-shielding teremp cloth piece(s) provided at the above opening, and which is characterized in that the wall of the container body is formed by paper board and a multilayer film superposed thereon containing a metal foil layer or a metallized flexible sheet layer being visible from the outside and that the ground fabric structure of the above teremp cloth is knit structure.This magazine is superior in moistureproofness, gas barrier, dustproofness, thermal-shielding, water proofness and antistatic property. Deformation of the opening for drawing out hardly occurs, and leakage of light and moisture do not occur. Even though this magazine is left in the sunlight for a long time, inner temperature of the magazine is not so raised. Quality of the photosensitive strip material packaged by this magazine is kept for a long period irrespective of outside conditions. The magazine of the invention is inexpensive, and its waste treatment is easy.
摘要翻译：一种用于感光条材料卷的盒子，其包括可旋转地支撑该卷筒的芯体和一个允许该芯部的遮光容器主体，并具有用于拉出感光条带材料的开口和设置有遮光的特布姆布片在上述开口处，其特征在于，容器主体的壁由纸板和叠置在其上的多层膜形成，其中包含从外部可见的金属箔层或金属化柔性片层，并且底布结构的上述特布布是针织结构。本杂志具有防潮，防气，防尘，防热，防水，防静电等优点。几乎不发生用于拉出的开口的变形，并且不会发生光和水分的泄漏。即使这本杂志长时间在阳光下，杂志的内部温度也不会升高。该杂志包装的感光条材料的质量保持长时间，不管外部条件如何。本发明的杂志廉价，废物处理容易。

摘要： A packaging material for photosensitive materials for photographic purposes which is a laminated film having light-shielding property and comprising,(a) a perforated film layer of a thermoplastic resin having a thickness of 7 to 150 .mu.m,(b) a spunbonded nonwoven fabric layer laminated on an adhesive layer which penetrates holes of said perforated film, and(c) a low-pressure linear low-density polyethylene film layer containing more than 50 weight % of a low-pressure linear low-density polyethylene resin and being located as the inner surface layer.The packaging material of the invention is superior in the small difference in tear strength between longitudinal direction and lateral direction, in physical strength, in heat sealing properties and in light-shielding property. As a result, its thickness can appreciably be made thinner than the conventional packaging material, and its cost is lowered. This packaging material is usable for a weight photosensitive material and for a roll having a sharp edge.

摘要： A laminated sheet is described, which comprises a porous sheet, and a uniaxially molecularly-orientated thermoplastic resin film bonded onto at least one side of the porous sheet through an adhesive layer. This laminated sheet has excellent physical strength and cushioning characteristics. Incorporation of a light-shielding substance into the laminated sheet makes it suitable for use as a wrapping material for light-sensitive materials.
