ABSTRACT:
The invention relates to the discovery that pre-treating mineral oxide particles with a silylated polymeric coupling agent prior to suspending the particles in a binder polymer increases the crack resistance and adhesion of particles to a inkjet printing substrate such as paper sheets. Such pretreatment also reduces the amount of binder needed to achieve acceptable performance, leading to improvements in production speed and image quality.
