PROBLEM TO BE SOLVED: To provide a synthetic rubber latex for a binder for synthetic fibers, pulp fibers, etc., excellent in wet strength without using a large amount of a formalin-releasing substance. SOLUTION: The latex is prepared by polymerizing an unsaturated monomer mixture comprising (a) a methylol derivative of an ethylenically unsaturated carboxylic acid amide, (b) an ethylenically unsaturated carboxylic acid amide, and (c) an aliphatic diene monomer, provided that 3≥weight ratio (a)/(b)≥0.15 and that the sum of amounts of (a) and (b) is 1-10 wt% based on the total amount of the unsaturated monomer mixture.
