| titleOfInvention | White keys for keyboard instruments |
| abstract | PROBLEM TO BE SOLVED: To provide a white key for a keyboard musical instrument, which has practically sufficient water absorption, has an ivory-like touch feeling, and effectively reduces the occurrence of chipping during repeated keystrokes. SOLUTION: The styrene copolymer (I) containing an unsaturated nitrile monomer unit and an aromatic vinyl monomer unit is 60 to 99% by mass, 1 to 40% by mass of the water absorbing component (II), In such a manner that the total of (I) and (II) is 100% by mass, A white key for a keyboard instrument, which is a molded product of a thermoplastic resin composition having a plane bending fatigue strength of 300,000 times or more at a stress of 19 MPa in a 30 ° C. environment in accordance with JIS K7119.
