Transfer laminate and method for manufacturing transfer laminate

Abstract

[Problem] A transfer printed laminate used for forming a circuit board and showing good stripping property even when no heat load is applied during the circuit formation process, and a method for manufacturing the transfer printed laminate are provided. [Solution] A transfer printed laminate sequentially comprises a substrate, a conductive layer, a stripping layer, and a conductive auxiliary layer. The conductive layer comprises copper; the stripping layer comprises an alloy of nickel and chromium or an alloy of nickel and copper; and the conductive auxiliary layer comprises copper. The maximum value of the oxygen concentration, determined by depth-direction compositional analysis using X-ray photoelectron spectroscopy in the thickness direction of the stripping layer, is
