Title:
LAMINATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/039990
Kind Code:
A1
Abstract:
Provided is a laminate manufacturing method comprising at least a step of using a slot die to simultaneously apply a plurality of coating liquids, including a first coating liquid and a second coating liquid, onto a continuously conveyed substrate, wherein: the first coating liquid is applied in a contacting manner on the substrate; the second coating liquid is applied adjacent to the first coating liquid; a ratio A/B of a solid content A of the first coating liquid and a solid content B of the second coating liquid is 0.1 or less; a difference (d1 – d2), in a slot that applies the second coating liquid, between a minimum distance d1 between the substrate and a downstream lip surface with respect to the substrate conveyance direction and a minimum distance d2 between the substrate and an upstream lip surface with respect to the substrate conveyance direction is 10 μm or greater; and the relationship between the minimum distance d2 and a thickness h of the coating formed by the second coating liquid is such that d2 > 3 × h.
