Title:

COPOLYMER AND METHOD FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2019/208111

Kind Code:

A1

Abstract:

Provided is a polymer having an excellent ability to inhibit dye transfer. The copolymer according to the present invention, which has structural unit (a) derived from an N-vinyllactam monomer (A) and structural unit (b) derived from a monomer (B) represented by any of formulae (1), (1') and (1''), is characterized in that the content of structural unit (b) is 1-99 mass% relative to 100 mass% of the total structural units.
