Abstract

PURPOSE: To enable distinct original images to be obtained and fixed within a short time at a low temperature ane enable sufficient printing resistance power to be obtained by using nitrile-rubber modified epxoy resin for the engraving toner composed primarily of resin and coloring agents.
CONSTITUTION: The product of reaction of the resin having average more than 1 or more reactive 1.2 epoxy groups per molecule such as bisphenol A type general- purpose epoxy regin or other and the carbosylated acrylonitrile-butadiene copolymer composed of AN 15 to 43%; BD 57 to 85%; carboxylic acid 15% or under is mixed together with coloring agents and other addtives. This mixture is thermally melted and kneaded then ground and is classified of the particles of 5 to 25μ, whereby the toner is prepared. Thereby, the toner which firmly sticks in a short time and at a low temperature (softening point 70 to 80°C) even to the surface such as dry offset plate having release characteristic is obtained.
