To provide a lenticular lens sheet having a fine light shielding pattern that has high color reproducibility. [MEANS FOR SOLVING PROBLEMS] The above problem can be solved by a lenticular lens sheet, in which the average primary particle diameter of carbon black contained in a light shielding layer is not less than 10 nm and not more than 50 nm and, preferably, in an image of the cross-section of the light shielding layer under scanning electron microscopic observation, the area ratio of carbon black to the whole image is not less than 60% and not more than 95%, and a process for producing the lenticular lens sheet.

A multi-layered tube composed of at least two layers, each formed from a different resin, e.g. resin (I) or resin (II). Resin (I) contains 5 to 40 mass % of a polypropylene resin and 95 to 60 mass % of at least one hydrogenated copolymer. Resin (II) contains 45 to 100 mass % of a polypropylene resin and 55 to 0 mass % of a hydrogenated copolymer. The multi-layered tubes may be used in the field of medicine and provide tubing which is excellent in transparency, flexibility and anti-kinking properties, and which is durable during sterilization procedures with high-pressure steam. The multilayer tubing may also be safely disposed of as it generates no toxic gases, such as dioxin, when incinerated. The multilayered tubing has excellent connectability and may be bonded to other tubing using hot solvent bonding or solvent adhesion. The multilayered tubing which is free from generation of any toxic gas when incinerated, and which is excellent in hot solvent bonding or solvent adhesion to other tube.

A balloon catheter and its pilot balloon system visually indicate the state of the inflation of a balloon placed in a human body. The small pilot balloon is conveniently manufactured by blow molding utilizing substantially the same material and has substantially the same structure as the main balloon. The pilot balloon is useful for a catheter with balloon or a tube with cuff where the balloon or the cuff is made of a very resilient material. The preferred material is a blend of composition having certain properties comprising styrenic thermoplastic elastomer and polyolefin.
