THE PRESENT INVENTION PROVIDES AN ACRYLIC RELEASE AGENT PRECURSOR, WHICH MAKES IT POSSIBLE TO PREPARE AN ACRYLIC RELEASE AGENT EFFICIENTLY AS MUCH AS POSSIBLE IN A COMPARATIVELY SMALL ULTRAVIOLET DOSE, REGARDLESS OF THE COMPONENT. AN ACRYLIC RELEASE AGENT PRECURSOR WHICH CONTAINS A POLY(METH)ACRYLATE ESTER HAVING A GROUP CAPABLE OF BEING ACTIVATED BY ULTRAVIOLET RADIATION AND HAS A STORAGE ELASTIC MODULUS OF 1X10² TO 3X106 PA AT 20°C AND A FREQUENCY OF 1 HZ, WHEREIN SAID PRECURSOR, AFTER IRRIDIATION WITH ULTRAVIOLET RADIATION, HAS A CONTACT ANGLE OF 15° OR MORE TO A MIXED SOLUTION OF METHANOL AND WATER (VOLUME RATIO OF 90/10) HAVING A WETTING TENSION OF 25.4 N/M. |
