A primer composition, and a method for its use to improve adhesion between a silicone substrate and a subsequently applied paint film, is disclosed. The primer composition consists essentially of a mixture of an alkoxysilane, an organotitanate and a tin salt of a carboxylic acid, each component being present in a specific critical molar proportion.

A fiber comprising a polymer filled with a material that imparts cut resistance to the fiber, is provided. The polymer may be a liquid crystalline polymer. Also provided is protective apparel containing the fiber, such as cut-resistant, safety gloves.

A device (Fig. 2) is revealed as well as a method for recording signals on a record carrier (1) with the aid of a radiation beam (15). The signals are recorded in the form of optically detectable marks (30, 31) in parallel tracks (4) which have a substantially constant track pitch. The recording intensity of the radiation beam (15) is set in such a way that with a "minimum" recording intensity, in...
