Abstract
1310780 Electro-photographp GAF CORP 14 Sept 1971 [23 Sept 1970] 42867/71 Heading G2H A positively charged developer composition comprises pigment dispersed in an insulating liquid in which is dissolved zirconium octoate or naphthenate (as charge control agent) and a C 15-22 alpha-olefin-alkylated poly-N-vinyl pyrrolidone (as dispersing agent), the mole ratio of the oleflnderived alkyl groups to the N-vinyl pyrrolidone residues being 0À1-5À0 to 1À0 and the proportions of zinc and of polymer to pigment being 0À15-0À3
