CARBON BLACK DISPERSION

摘要

The problem to be solved by the present invention is: to provide a carbon black dispersion containing well-dispersed carbon black and giving a black composition superior in thermal resistance; to provide a black composition giving a black shaped body which is colored in black of a desired density and superior in thermal resistance; and to provide a dispersion method of carbon black that allows preferable dispersion of carbon black in a short period of time, and preparation of a carbon black dispersion that gives a black composition superior in thermal resistance. In order to solve the above described problems, carbon black is dispersed in a solvent containing N,N,N',N'-tetramethyl urea, by using polyamic acid.
