摘要:
Novel epoxy acrylates and carboxyl group-containing epoxy acrylates of formulae II and III of the claims that are relatively highmolecular and are chemically crosslinkable can be used in photoresist formulations with the additional use of highly polymerised polymer binders. Such resist formulations are used in particular in the field of printed circuit boards and printing plates, are applicable from aqueous medium, are almost tack-free and have very good edge coverage, especially on conductors.
摘要:
A process for ensuring a neutral vehicle handling during cornering and a simultaneous load change is provided by the operation of a vehicle system having at least one driven axle, an axle differential gear, wheel brakes for the selective deceleration of an individual wheel, a device for recognizing a cornering and a device for recognizing a coasting operation and for generating a signal corresponding to the intensity of the coasting operation. The problem of rear-wheel driven and front-wheel driven vehicles is the vehicle handling during cornering in the coasting operation. As a result, depending on the method of operation, an oversteering or understeering of the vehicle is caused. The process avoids these problems in that, during a cornering, a wheel of the driven axle is decelerated at least as a function of the coasting operation signal such that the moment generated thereby, such as a counter-yawing moment, compensates the yawing moment caused by the cornering during the coasting operation.

摘要:
Titanocenes with .pi.-cyclopentadienyl ligands, in which one or two carbocyclic or heterocyclic aromatic rings are bonded to the metal, the aromatic rings being substituted in at least one of the two ortho-positions relative to the metal-carbon bonds by CF.sub.2 Z (Z=F or substituted or unsubstituted alkyl), are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds. They are distinguished by a high radiation sensitivity, stability to air and thermal effects, and high effectiveness in the range from UV light to visible light.
