Beschreibung
Zusammenfassung:	The present invention relates to an aqueous white toning agent, which comprises: 2 to 10 parts by weight of polypropylene glycol; 2 to 6 parts by weight of an acryl type dispersant in a form of a block copolymer; 2 to 6 parts by weight of a polymer carboxylic acid type dispersant; 2 to 6 parts by weight of a modified fatty acid polymer type dispersant; 60 to 80 parts by weight of a white pigment having TiO_2 content of at least 93%; and 10 to 20 parts by weight of water. The aqueous white toning agent can adjust the concealed power by adjusting the transparency and proportioning for toning due to the high content of the pigment, thereby being very easily applied to an aqueous white basecoat paint which has generally poor concealed power and then has poor paintability. 수성 백색 조색제는 폴리프로필렌 글리콜 2 내지 10중량부, 블록 공중합체 형태의 아크릭 타입 분산제 2 내지 6 중량부, 고분자 카복실산 타입 분산제 2 내지 6중량부, 변성 지방산 폴리머 타입 분산제 2 내지 6 중량부, TiO2 함량이 93% 이상인 백색 안료 60 내지 80중량부 및 물 10 내지 20 중량부를 포함한다. 이러한 수성 백색 조색제는 안료의 함량이 높아 조색용 투명과 비율 조정으로 은폐력을 조정할 수 있기 때문에 일반적으로 은폐가 떨어져 도장 작업성이 떨어지는 수성 백색 베이스코트 도료에 매우 용이하게 적용된다.
