PROBLEM TO BE SOLVED: To be mixed with synthetic rubber latex such as styrene / butadiene latex (SBR latex), nitrile / butadiene latex (NBR latex), methacrylic ester / butadiene latex (MBR latex), to impart flexibility and improve texture. To provide a water-soluble phenolic resin composition that can improve adhesion and is useful for impregnation and coating of various substrates such as fibrous substrates and glass rovings, and a binder containing the same. SOLUTION: The molar ratio (F / P) of phenol (P) to formaldehyde (F) is 1.0 / 1.0 to 3.0 / 1.0, and lithium hydroxide as a catalyst is 0 with respect to phenol. A water-soluble phenol resin composition obtained by reacting with 10 to 0.50 mol and the water-soluble phenol resin composition. [Selection figure] None. |
