Document Type and Number:
WIPO Patent Application WO/2022/137914
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an organic solvent-based composition which can be adhered to a base material and from which it is possible to form a coating that is detachable from the base material when being treated with warm water or an alkaline solution; a laminate having a coating formed using the organic solvent-based composition; and a method for producing a recycled base material obtained through detaching of the coating. Said problem can be solved by an organic solvent-based composition in which an acid value of a solid content thereof is 1-150 mgKOH/g. The organic solvent-based composition preferably contains an acidic additive. The acid value of said acidic additive is preferably 3-900 mgKOH/g.
