Comparative example 1
The invention can improve the bonding strength of the base layer and the aluminum foil by pretreating the aluminum foil. This comparative example omits step a of the example and directly cures the base layer on the surface of the aluminum foil according to step B. Then, the aluminum foil with a base layer prepared in this comparative example and the above examples was subjected to a polishing test (the base layer was polished with 500-mesh sandpaper for 30 seconds at a polishing pressure of 2kg), and the average thickness of the base layer before and after polishing was measured:
| before grinding (mu m) | After grinding (mum) | |
| Examples | 78 | 51 |
