A carriage cooperates with a cable way machine with an oblique multigroove pulley and a friction drive drum, so oriented that the cable runs in straight directions off and onto circular grooves of the drum. One cable portion runs from the cable way machine through the carriage towards a fixed anchoring point, the remaining cable portion runs also through the carriage to a tension biasing anchoring point; function and configuration of a main cable and of a hauling cable are thus combined.
The present invention relates to a process for preparing dye-comprising aqueous polymer dispersions by free-radical aqueous emulsion polymerization of ethylenically unsaturated monomers in the presence of free-radical initiators, in which at least some of the monomers are employed in the form of an oil-in-water emulsion E1 whose disperse phase comprises at least one oil-soluble dye, wherein the disperse phase of E1 is formed essentially of dye-comprising monomer droplets having a diameter <500 nm. The present invention also relates to perylene dyes of the formula III as set forth in claim 35. The present invention relates in addition to dye-comprising formulations which comprise the dye-comprising polymers of the invention and to pigmented formulations which comprise a polymer of the invention comprising optical brightener.
