PROBLEM TO BE SOLVED: To obtain particles which show an excellent anti-blocking property by blending them into polyolefin film, do not lower the haze, and allow little dropout of particles, and to provide a method for producing the particles. SOLUTION: These acrylic anti-blocking particles for polyolefin consist of acrylic resin particles which have a 'minimal diameter'/'maximal diameter' ratio of 0.95 or less, and contain non-spherical particles at 50% or more by number, wherein the non-spherical particles are nearly disc-shaped, and have an average maximal diameter (D1) of 1-10μm, an average minimal diameter (D2) of 0.8-10μm, an average thickness (T1) of 0.4-6.0μm, a D2/D1 ratio of 0.8-1.0, and a T1/D1 ratio of 0.4-0.7.
