Claims (1)
고분자 형태의 색소를 얻고자 하는 목적으로서 알긴산(갈조류의 구성분)을 암모늄화 한후 고분자 형태시 아미드화하여 디아조화한 염화 알긴산 디아조늄을 사용하는 디아조 색소의 제조 방법과 알긴산 나트륨 또는 알긴산 아미드를 α할로 카르복실산 반응후 알카리 용해하여 환원제에 의한 고분자 상태의 류코형 화합물을 이루는 색소의 제조 방법.For the purpose of obtaining a pigment in the form of a polymer, a method of preparing a diazo pigment using a diazoated alginate diazonium, which is amidated by ammonization of alginic acid (components of brown algae) and then amidated in a polymer form, and sodium alginate or alginate amide A method for producing a pigment, wherein the alkali is dissolved after the α-halo carboxylic acid reaction to form a leuco-type compound in a polymer state by a reducing agent.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
