<p>PURPOSE:To obtain the artificial keyboard material which is close in sense of touch, playing ability, and durability to natural ivory by dispersing porous particles in a polymer matrix. CONSTITUTION:An infinite number of porous particles 2... are dispersed in the polymer matrix made of acrylate resin 1, etc., which contains no hydroxyl group and exposed in an abrasive surface 3, and pores are also exposed in the surface. Keys are formed of the keyboard material itself or by forming the keyboard material on a sheet and then sticking it on key stroke part on the surface of a key base material made of timber. Thus, the porous particles 2 can be dispersed, so proper water absorptivity is obtained to absorb sweat from fingers of a player well, the weatherability is superior and close to that of ivory, and a superior feeling is obtained.</p> |
