摘要： The invention relates to an arrangement for color detection when evaluating printed materials, maps or the like in that a color pattern under investigation is arranged substantially in the plane of a reference color pattern and both being cyclicly detected by an opto-electronic detection unit. The detector, itself consists of only one opto-electronic transducer comprising a plurality of detecting faces which receive the color informations from an illumination source reflected at both color patterns. The opto-electronic transducer is followed by an evaluation electronic means which compares the reference color pattern and the investigated color pattern and associates the respective patterns.

摘要： Epoxidized polybutadienes with an average molecular weight of 500 to 100,000 and a certain content of epoxide oxygen were prepared from the corresponding polybutadienes with use of perpropionic acid in a benzene solution. The solution can also be employed in unpurified form with maximum contents of 1.5 weight percent hydrogen peroxide 1.5 weight percent of water, and about 800 ppm of mineral acid.
