Abstract
A soft resin pellet is provided comprising at least one liquid (B) having a kinematic viscosity at 25° C. ranging from 0.5 to 100,000 cSt (centistokes) and a surface tension at 25° C. ranging from 10 to 50 dyn/cm, and at least one fine powder (C) of an average particle diameter of not more than 50 μm, which fine powder adheres to the surface of pellets of at least one soft resin having a tensile modulus determined according to ASTM D-658 not higher than 1600 Mpa.
