    摘要: A transparent liquid container bottle features a label with a tinted backside which imparts a tinted appearance to the contained liquid. The bottle has a cylindrical body, a hemispherical top and a base cup. The base cup may be tinted to match the backside of the label. The label covers only part of the cylindrical body, leaving an unlabeled section with a dimension 0.1 to 2.0 times, or 0.5 to 1.2 times preferably, the diameter of the body.

    摘要: Provided is a presensitized planographic printing plate requiring no dampening water for use in negative work which comprises a base substrate, a photosensitive layer secured to and overlying the base substrate, and containing an orthoquinonediazide compound and having a content of ethanol-soluble component not higher than 20% by weight, and a silicone rubber layer overlying the photosensitive layer through bonding component. When the printing plate is exposed through a negative film and then treated with a developer, the photosensitive layer in the exposed image areas is dissolved and the corresponding portion of the silicone rubber layer is also removed easily and is obtained image as an exact reproduction of the negative film. Dampening water is not required when printing is carried out.
