A composition for anti-reflective coating material is disclosed, comprising a polymer compound having repeating units having specific structure, and optionally a melamine, guanamine, urea, phenol, naphthol or hydroxyanthracene compound substituted by at least one group selected from the group consisting of a methylol group and an alkoxymethyl group at two or more positions. The composition for anti-reflective coating material of the present invention is effective for the reduction of adverse effects of reflection by the substrate in a lithographic process using various radiations. A resist pattern formation process which comprises the use of the composition for anti-reflective coating material is also disclosed.
