Title:
COATING COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/171620
Kind Code:
A1
Abstract:
The purpose of this invention is to provide: a coating composition with outstanding storage stability, which has few limitations as to components to be added thereto, such as pigments, and which is easy to apply; and a method for producing same.
This coating composition is characterized by containing cellulose nanofibers satisfying conditions (A) to (E) below, a water-miscible organic solvent, water and a pigment, the mass ratio of pigment content to cellulose nanofiber content falling within the range of 60-500, inclusive.
(A) Number-average fiber width in the short width is from 2 nm to 500 nm, inclusive.
(B) Average aspect ratio is from 500 to 1000, inclusive.
(C) Has cellulose I-type crystalline structure.
(D) Has an anionic functional group.
(E) An organic compound having an organic value not exceeding 450 in the organic conceptual diagram is ionically bonded to an anionic functional group
