고체 표면은 (i) 51 또는 52 부피% 이하의 양으로 존재하는 가교된 아크릴 또는 불포화 폴리에스테르 수지, 및 (ii) 필러 입자에 결합되거나 부착된 불연속 기능성 입자로 개질되고 고체 표면 전체에 걸쳐 고르게 분포된, 48 또는 49 부피% 이하의 무기 필러 입자를 포함하되, (a) 필러 입자의 95~99 부피%는 0.5 내지 10 미크론 이하 범위의 장축 치수를 갖고, (b) 필러 입자의 D50은 0.5~2.5 미크론이고, (c) 필러 입자의 D90은 10 미크론 이하이고, (d) 필러 입자는 필러 입자에 결합되거나 부착된 불연속 기능성 입자로 개질되어 있다. A solid surface comprises (i) a crosslinked acrylic or unsaturated polyester resin present in an amount no greater than 51 or 52 volume fraction percent, and (ii) no greater than 48 or 49 volume fraction percent of inorganic filler particles that are modified with discrete functional particles that are bound, or adhered to the filler particles, the filler particles being distributed evenly throughout the solid surface wherein (a) 95-99 volume fraction percent of the filler particles has a major dimension in the range of from 0.5 to no greater than 10 microns, (b) the D50 of the filler particles is from 0.5-2.5 microns, (c) the D90 of the filler particles is equal to or less than 10 microns and (d) the filler particles are modified with discrete functional particles that are bound, or adhered to the filler particles.
