Beschreibung
Zusammenfassung:	The invention relates to a stripping agent containing an alkylamide mixture. The stripping agent containing an alkylamide mixture comprises 50-70wt% of N-methylformamide, 30-50wt% of N,N-dimethylacetamide, and the balance water. The stripping agent containing an alkylamide mixture has water intersolubility, no corrosivity to copper or a copper alloy, and no toxicity to human and the environment. Because the stripping agent containing an alkylamide mixture only comprises the two main ingredients, the used stripping agent can be easily recovered by fractionation and is restructured into an original formula for recycle in the manufacturing process, thus the effects of reducing a cost and protecting the environment are achieved. The invention further provides a method for removing light resistance by the stripping agent containing an alkylamide mixture.
