Abstract
The present invention provides green and red conversion films capable of keeping a sufficient intensity of converted light over a long period, and a multicolor emission organic EL device which exhibits light-emitting properties stably over a long period. The present invention includes a pendant-type polymeric compound characterized in that the pendant-type polymeric compound contains at least one repeating unit represented by a general formula (1) and at least one repeating unit represented by a general formula (2), (6) or (7), wherein n/(m+n)=1/100 to 100/100 provided that the molar ratio of (1):(2), (6) or (7) is m:n.
