<p>This invention provides the following: a printed-circuit-board material wherein the top surface of a copper or other metal film is resistant to smearing, and even if smearing does occur, said smearing is easy to remove; and a printed circuit board using said printed-circuit-board material. Said printed-circuit-board material contains the following: a binder component; cellulose nanofibers having a number-average diameter between 3 and 1,000 nm, inclusive; and an acrylic-copolymer compound. Said printed-circuit-board material is suitable for use as a solder resist or as an interlayer insulation material for multilayer printed circuit boards. This printed circuit board uses said printed-circuit-board material.</p> |
