This invention pertains to the polyurethane composition with hydrophilicity and hydrolysis resistance. The purpose of this invention is achieved by:
1) A polyurethane molecule containing at least one acidic hydrophilic group in the molecule is neutralized with piperidine derivatives or piperazinone derivatives, or
2) A mixture containing polyurethane and compound(s) having at least one acidic hydrophilic group is neutralized with piperidine derivatives or piperazinone derivatives.
The invention polyurethane compositions which have excellent hydrolysis resistance and rupture strength are useful for adhesives, paints, and binding agents for magnetic recording media.
