Document Type and Number:
Japanese Patent JP3552065
Kind Code:
B2
Abstract:
PURPOSE:To provide the subject material comprising a (meth)acryloyl group- containing copolymerizable compound, a specific reaction type antistatic agent and a specific oligomer, excellent in antistaticity, and capable of sufficiently preventing the staining of recording media. CONSTITUTION:This material comprises (A) a (meth)acryloyl group-containing copolymerizable compound, (B) a reaction type antistatic agent having a quaternary ammonium salt group (quaternary NH4 salt group), alkylene glycol chains (AG chains), a >=4C hydrocarbon group and a copolymerizable group (preferably a compound of formula I), and (C) an oligomer having a quaternary NH4 salt group, AG chains and a >=4C hydrocarbon group, and not containing a polymerizable group. The component C is obtained e.g. by copolymerizing a quaternary NH4 salt group-containing monomer of formula II (R11 is H, CH3; R12-R14 are H, alkyl, etc.; A is alkylene, hydroxyalkyl; X<-> is anion), an AG chain-containing monomer of formula III (R., is alkylene; R16 is H, aryl, etc.; m 1-15), and a >=4C hydrocarbon groupcontaining monomer of formula IV [R12 is H, (meth)acryloyl; n is 4-30].
