PURPOSE:To obviate drop-out of printing by a soft PVC and to improve environmental resistance and fixing strength by using a specific copolymer as a binder resin. CONSTITUTION:This toner contains the copolymer which contains the comp. expressed by formula I and the compd. expressed by formula II as essential monomer components and contains at least 5wt.% the component expressed by formula I and 0.05-20wt.% component expressed by formula II in the constituting components of the polymer as the binder resin. In formulas I, II, R1 denotes hydrogen or methyl group; R2 denotes an alkylene group of 1-6C or divalent org. group having an alicycle or arom. ring; R3 denotes a prescribed group; R15, R16 respectively independently denote an alkyl group of 1-6C, etc. Generation of the drop-out of printing is thereby obviated even if the printed matter is sandwiched in sheets made of the soft PVC polymer; in addition, the environmental resistance and fixing strength are improved. |
