FIELD: electrography, dry toners used in combination with magnetic and stage carriers for development of latent electrostatic image on copies in positively charges electrographic layers. SUBSTANCE: novelty of proposed electrographic toner consists in usage of binder - cycloalcanonformaldehyde resin in the amount of 80-99 per cent by mass. Simplified composition of components of toner and stable technological indices make it economically profitable both for users and manufactures thanks to its low production cost from waste of caprolactam production. EFFECT: production of electrographic toner economically profitable both for users and manufacturers. |
