The title compound, C(19)H(34)N(+)·C(10)H(7)O(4)S(-), is a charge-control agent used for toners in electrophotography. In the crystal structure, centrosymmetric anions associate through O-H⋯O hydrogen bonds formed between the O-H group of one anion and the sulfonate O atom of a neighbor. The components of the dimer are offset with respect to each other so that the separation between the two par...

1 Short History The technology that makes laser printers work goes back to the first xerographic copiers, produced about sixty years ago. The inventor was a patent attorney named Chester Carlson. Chester collaborated with Battelle Memorial Institute in 1944 and then in 1947 with a small company named Haloid Corporation in Rochester, NY to develop the first copier. Haloid eventually changed its ...

We study how paper microstructure heterogeneity affects the electrostatic field acting on toner particles during xerographic printing. We use an efficient multigrid Poisson solver to simulate electrostatic fields. The dielectric distribution of paper is obtained either analytically or input numerically using a recently developed 3D fibre network model of paper. Simulations are used to elucidate...

The title mol-ecular salt, C(19)H(34)N(+)·C(10)H(7)O(5)S(-), is a charge-control agent used for toners in electrophotography with a high melting point of 508 K. In the crystal structure, the anions form inversion dimers, linked by pairs of O-H⋯O hydrogen bonds. Further O-H⋯O links between dimers generate anionic sheets propagating in (010). One of the n-butyl chains of the cation is disordered ...
