Pressure-Sensitive Adhesive Sheet for Laser Processing and Method for Laser Processing |
摘要 |
<p>The present invention provides a pressure-sensitive adhesive sheet for laser processing, which includes a base and a pressure-sensitive adhesive layer provided on one surface of the base, the pressure-sensitive adhesive layer having an absorption coefficient at a wavelength of 355 nm of from 50 cm -1 to 900 cm -1 , the pressure-sensitive adhesive layer containing a light-absorbing agent in which an absorbance of the light-absorbing agent in a 0.01% by weight acetonitrile solution at a wavelength of 355 nm is from 0.01 to 1.20, and in which the pressure-sensitive adhesive sheet is to be used at the time when a workpiece is laser-processed by a laser light having a wavelength of an ultraviolet region or a laser light enabling light absorption via multiphoton absorption process.</p> |
