PURPOSE:To obtain always stable pictures in the stage of continuous and discontinuous repetitive copying by using an unsatd. polyester resin contg, 40- 70wt% a vinyl monomer as a binder resin. CONSTITUTION:A binder resin for dispersing and containing a photoconductive material consists of an unsatd. polyester resin contg. 40-70wt% a vinyl monomer. The vinyl monomer is examplified by styrene, vinyl toluene, vinyl acetate, methyl methacrylate, triallyl cyanurate, diallylphthalate, etc. |
