The Mass Spectra profile of 1-Amino-2-naphthol shows three major peaks at 159 m/z (which is the molecular weight of the compound having 100% intensity), 130 m/z (70% intensity), and at 103 m/z (15% intensity). What is the mechanism of fragmentation of the compound? What are the compounds that are being formed after fragmentation at 130 and 103 m/z? 

Kindly elucidate the fragmentation mechanism so that I can correlate with other naphthalene derivatives.

Thank You
