Abstract: A collection of resin particles is provided, wherein the resin particles comprise one or more polymers; wherein the polymer comprises methylene bridge groups between aromatic rings; wherein the polymer comprises a total amount of amino groups bonded to the resin particles of 0.1 to 1.4 equivalents per liter of the collection of resin particles; wherein quaternary ammonium groups bonded to the polymer are either absent or else are present in an amount of 0.05 equivalents or less per liter of the collection of resin particles; wherein the resin particles have water retention capacity of 40% to 50% by weight of water based on the weight of the collection of resin particles; and wherein the resin particles have surface area of 100 m 2 /g or less.
