摘要： PROBLEM TO BE SOLVED: To provide a sizing composition that contains a water-dispersible or water-soluble blocked isocyanate having a significantly lower deblocking temperature as compared with the prior art of a curing agent.
SOLUTION: The sizing composition contains the water-dispersible and/or water-soluble alkylamine-blocked polyisocyanate, a film-forming resin, a coupling agent and a lubricant. The isocyanate is preferably synthesized from at least one polyisocyanate, at least one ionic and/or potentially ionic and/or nonionic compound and at least one blocking agent in which at least 20 mass% is an aralkyl amine.
