PROBLEM TO BE SOLVED: To provide an impregnated paper free from formaldehyde being the cause of sick building syndrome, exhibiting excellent dimensional stability when absorbing water, and having excellent impact resistance and interlaminar strength.SOLUTION: The impregnated paper for a floor material, formed by coating or impregnating a coating liquid at least containing a thermoplastic resin on or into an impregnation base paper is obtained by adding 5-30 mass% of an inorganic filler based on a raw material pulp, and 0.1-5 mass% of a silane coupling agent based on the inorganic filler to the inside of the impregnation base paper, and using a butadiene-based latex resin or an acrylic latex resin as the thermoplastic resin. |
