PURPOSE:To obtain the title sheet excellent in coherence and disintegrability in water, useful for electromagnetic wave shielding materials, electrophotographic printing plate-making materials etc., by papermaking from pulp and carbon fiber coated with a specific copolymer. CONSTITUTION:The objective sheet can be obtained by papermaking from (A) pulp and (B) carbon fiber coated with a copolymer from (1) a diamine compound, (2) a dicarboxylic acid compound, and (3) a glycidylated polyalkylene oxide derivative of the formula (R1 is H or 1-20C alkyl; R2 is H or methyl; n is 1-40) with the content of the component (3) being 10-50wt.% in terms of monomer composition. |
