Abstract: Method of producing a particle or group of particles having a coating of at least two, preferably at least three, outside each other located thin layers of interacting polymers, at which the particle or group of particles is treated in consecutive steps with solutions of the interacting polymers. Excess of the previous polymer is removed between each treatment step alternatively the respective polymer is added only in such an amount in each step that substantially all polymer is absorbed to the particle surface. It is also referred to a paper- or nonwoven product containing fibers and/or fillers containing particles or groups of particles of the mentioned kind.
