Abstract
Abstract A resin composition comprising (I) a granular or powdery resin which is a condensation product of a phenol, an aldehyde and optionally a nitrogen-containing compound having at least two active hydrogens and is characterized by (A) containing spherical primary particles and their secondary agglomerated particles each having a particle diameter of 0.1 to 150 microns, (B) having such a size that at least 50% by weight thereof can pass through a 100 Tyler mesh sieve, and (C) having a free phenol content, determined by liquid chromatography, of not more than 500 ppm, and (II) at least one member selected from the group consisting of (1) a rubbery elastic material, (2) a thermoplastic resin and (3) a curable reisn other than said granular or powdery resin (I) and/or a filler material other than said granular or powdery resin (I).
