Abstract
Abstract Crosslinked polymer microparticles having a mean grain diameter of 0.01 to 10µ the polymer of which carries urea, urethane or amide groups. The invention also provides a coating composition containing said crosslinked polymer microparticles, which has excellent application characteristics and storage stability and is capable of giving a coating with excellent film properties.
