【発明の名称】ポリマー状硼酸アンモニウムおよびその製造方法
Document Type and Number:
Japanese Patent JP2898448
Kind Code:
B2
Abstract:
Polymeric ammonium borates having a molecular weight of from about 5000 to about 500,000, obtained by homopolymerisation of monomers, for example diallyldialkylammonium chloride, and by copolymerisation of mixtures of two monomers, for example diallyldimethylammonium chloride and diallylmethyloctylammonium chloride, having a molar monomer ratio of from about 0.5:0.5 to about 0.95:0.05 in the copolymer, and optionally subsequent anion exchange, and mixtures of these compounds, are suitable as colourless charge-control agents in toners and developers for electrophotographic recording processes and as charge-improving agents in powders and paints for surface coating.
