Abstract
A process for the multiple coating of objects or webs which are continuously moving past a coating point, using coating apparatus according to the curtain coating process. This process is carried out such that any number of comparatively high viscosity layers is embedded between an accelerating layer which is positioned below the layers and has a viscosity range of from 1 to 20 mPas and a layer thickness of from 2 to 30 .mu.m, and a spreading layer which is positioned above the comparatively high viscosity layers and has a viscosity range of from 1 to 10 mPas and a layer thickness of from 5 to 20 .mu.m. By the curtain coating process, coating rates of 400 m/min and more may be achieved with a good coating quality.
