The present invention addresses the problem of providing a surface treatment layer which uses a material that contains water, and which is suppressed in gloss change during drawing, while having excellent peel strength and ethanol resistance. A surface treatment layer which comprises a primer layer (i) and a top coat layer (ii), and which is characterized in that: the primer layer (i) is formed from a resin composition for primer layer formation, said composition containing a urethane resin (A), an olefin resin (B), a filler (C) and water (D); the gloss value of the primer layer (i) is less than 0.9; the top coat layer (ii) is formed from a resin composition for top coat layer formation, said composition containing a urethane resin (X), beads (Y) and water (Z); and the filling rate of the beads in the top coat layer (ii) is within the range of from 25% to 90%. |
