The present invention provides a polyketone composition comprising a linear alternating polyketone polymer comprising carbon monoxide and at least one ethylenically unsaturated hydrocarbon, titanium dioxide and a dye of blue series. On the other hand, the polyketone composition of the present invention has the same level of mechanical properties as those of conventional polyketone materials, and at the same time, whiteness is greatly increased. Therefore, the composition can be widely used in a variety of fields such as cosmetics such as lip spring and tube which require chemical resistance, impact resistance and aesthetics, and a home appliance industry such as a water purifier head connector and a water valve. 본 발명은 일산화탄소와 적어도 1종의 에틸렌계 불포화 탄화수소로 이루어진 선상 교대 폴리케톤 폴리머, 이산화티타늄 및 청색 계열의 염료를 포함하는 폴리케톤 조성물을 제공한다. 한편, 본 발명의 폴리케톤 조성물은 기존 폴리케톤 소재 대비 기계적 물성이 동등한 수준이면서 동시에 백색도가 크게 증가되는 효과가 있다. 따라서 내화학성, 내충격성, 심미성 등이 요구되는 립 스프링(lip spring), 튜브(tube) 등의 화장용품 부품, 정수기 헤드 커넥터, 수도 밸브 등의 가전제품 산업 등 각종 분야에 폭 넓게 사용될 수 있다.
