PRESSURE-SENSITIVE FINE COMPOSITE PARTICLES AND LABEL SHEET

摘要

PROBLEM TO BE SOLVED: To provide pressure sensitive adhesive fine composite particles without affecting environmental aspects and a label sheet using the same.

SOLUTION: The pressure-sensitive fine composite particles are prepared by coagulating fine particles of an emulsion type adhesive by using a water dispersible isocyanate compound. The label sheet is prepared by applying an adhesive layer comprising the pressure sensitive composite fine particles on a side surface of a support sheet. The pressure-sensitive fine composite particles are prepared by mixing the water dispersible isocyanate compound with a dispersion prepared by dispersing the emulsion type adhesive in water and heating the dispersion at ≤90°C.
