PURPOSE:To obtain the titled agent capable of improving a fixing and a dispersion properties by using a resin obtd. by cross-linking a copolymer of specific monomers with isocyanate to the titled agent. CONSTITUTION:The copolymer obtd. by copolymerizing the monomers shown by formulas I and II is cross-linked with the isocyanate compd. In the formulas, R1 is H or CH3 group, R2 is 6-20C alkyl, R3 is OH or -O(CH2)nOH [(n) is a positive integer of 1-4] or -NHCH2OH. As the polymer having the cross- linking type structure has properties of swelling and dispersing in a carrier solution, in case that said polymer is used for a toner (a particle absorbed a resin to an image forming agent), the resin is fixed on a cured image whereby the toner does not peel in the printing, and has an excellent anti-printing and anti-rubbing properties of the image in an electrostatic printer. |
