A radiation-curable heat-peelable pressure-sensitive adhesive sheet is disclosed which has tackiness enabling adherends to withstand transportation and other steps, with which cutting can be conducted without flinging up an adhesive waste or causing chipping, and from which the cut pieces can be easily separated and recovered. The radiation-curable heat-peelable pressure-sensitive adhesive sheet comprises a substrate and, formed on at least one side thereof, a pressure-sensitive adhesive layer containing heat-expandable microspheres and a radiation-curable compound. A work to be cut is placed on the surface of the pressure-sensitive adhesive layer of the radiation-curable heat-peelable pressure-sensitive adhesive sheet, and the pressure-sensitive adhesive layer is irradiated with a radiation to cure the adhesive layer. The work is cut into pieces and the pressure-sensitive adhesive layer is then thermally foamed, before the cut pieces are separated and recovered from the adhesive sheet. Thus, cut pieces can be efficiently produced without arousing troubles in processing steps.

Uma folha adesiva pressure-sensitive do calor-peelable radiation-curable é divulgada de que tenham o tackiness permitindo adherends de suportar o transporte e as outras etapas, com de que o corte pode ser conduzido sem arremessar acima de um adesivo waste ou causar se lascar, e de qual as partes do corte podem fàcilmente ser separadas e recuperado. A folha adesiva pressure-sensitive do calor-peelable radiation-curable compreende uma carcaça e, dado forma ao menos em um lado disso, em uma camada adesiva pressure-sensitive que contem microspheres calor-expansíveis e um composto radiation-curable. Um trabalho a ser cortado é colocado na superfície da camada adesiva pressure-sensitive da folha adesiva pressure-sensitive do calor-peelable radiation-curable, e a camada adesiva pressure-sensitive irradiated com uma radiação para curar a camada adesiva. O trabalho é cortado em partes e a camada adesiva pressure-sensitive é espumada então tèrmica, antes das partes do corte são separados e recuperados da folha adesiva. Assim, as partes cortadas podem eficientemente ser produzidas sem despertar problemas em etapas processando.
