| 摘要 |
The invention is a flexible plate, suitable for use as a flexographic printing plate, comprising a flexible substrate primed with an aziridine functional material, and, contacting a primed surface of said substrate, a photosensitive layer which comprises a substantially polar acrylate compound, an elastomeric block copolymer, and a photoinitiator. The adhesion between the substrate and the photosensitive layer is strengthened by use of the aziridine functional primer in combination with a substantially polar acrylate compound. In contrast, when acrylate compounds with large nonpolar portions are used, the adhesion tends to be poor. The adhesion is further improved by exposure of the plate to radiation.
