Abstract
The support board for perforation processing 1 of the present invention having a lubrication layer 3 formed on at least one surface of an aluminum substrate 2 is characterized in that the lubrication layer 3 is made of a mixture containing crystalline water-soluble resin and crystal nucleation agent. This structure provides a support board for perforation processing having a lubrication layer excellent in adherence to an aluminum substrate, free from stickiness, and excellent in blocking prevention, and capable of easily being washed after processing.
