    摘要： The invention relates to a surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt or a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active materiaI from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

    摘要： The application relates to a method for controlling contact area of a paper or board substrate (13) by depositing a trace amount of particles (11) on the surface of said substrate, and to a paper or board substrate treated in this way. The use of electrostatic deposition of coating materials, e.g. calcium stearate, alkyl ketene dimer (AKD) gives improved control on contact and surface characteristics. The particles are deposited in an amount ranging form 10 -5 - 10° g/m 2.
