Title:
COPPER ELECTROLYSIS SOLUTION CONTAINING COMPOUND HAVING SPECIFIC SKELETON AS ADDITIVE, AND ELECTROLYTIC COPPER FOIL PRODUCED THEREFROM
Document Type and Number:
WIPO Patent Application WO/2006/080148
Kind Code:
A1
Abstract:
This invention provides a low profile electrolytic copper foil having a small surface roughness on the rough surface side (side remote from gloss surface) in the production of an electrolytic copper foil using a cathode drum, particularly an electrolytic copper foil which can realize fine patterning and has excellent elongation and tensile strength. There is also provided a copper electrolysis solution which can realize even copper plating on a two-layer flexible substrate without pinholes. The copper electrolysis solution contains, as an additive, a compound having a specific skeleton represented by general formula (1) produced by an addition reaction of a compound having one or more epoxy groups per molecule with water. (1) wherein A represents an epoxy compound residue; and n is an integer of 1 or more.
