    摘要: Polymeric particles comprising a polymeric matrix that has been formed from a blend of monomers comprising a first monomer which is an ethylenically unsaturated ionic monomer and a second monomer which is an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C., wherein secondary particles are distributed throughout the matrix, in which the secondary particles comprise a hydrophobic polymer that has been formed from an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C. and optionally other monomers, which hydrophobic polymer is different from the polymeric matrix. Also claimed is a process for preparing particles. The particles have improved shatter resistance. Preferably the polymeric particles comprise an active ingredient, especially a colorant. Such particles combine improved shatter resistance with the ability to retain the active ingredient. The particles of the invention can be used in a variety of industrial applications, for instance in the manufacture of inks, paper and cosmetics.
