    摘要： Process for the manufacture of foams with the aid of blowing agents containing fluoroalkanes and fluorinated ethers, and foams obtained by this process. The invention relates to a process for the manufacture of foams based on polyisocyanates by the reaction of polyisocyanates, compounds containing at least two hydrogen atoms reactive towards isocyanate groups, blowing agents and, if appropriate, other additives. The blowing agents used consist to the extent of at least 10 mol % of at least one fluoroalkane of formula (I), C.sub.a H.sub.b F.sub.c, where a=2-6, b=1-12, and c=2-13, and at least one fluorinated ether of formula (II), C.sub.a H.sub.b F.sub.c O-C.sub.d H.sub.e F.sub.f, where a=1-6, b=1-12, c=1-12, d=1-2, e=0-5 and f=0-5. The invention further relates to the foams obtained by this process.

    摘要： An electrophotographic recording material comprising an electrically conducting layer support, an optional insulating intermediate layer, a photoconductive layer comprising at least one dyestuff as charge carrier-generating compound, and a layer containing a binder and photoconductor as charge-transport compound contains, as dyestuff in the photoconductive layer, a benzo-benzimidazo[1,2a]-quinoline derivative, preferably one represented by the formula ##STR1## Use of the dyestuff, in combination with a wide variety of photoconductors and binders, yields materials with excellent electrophotographic properties.
