TACKY ADHESIVE CURABLE BY ULTRAVIOLET RAY AND CONTAINING DISPERSED HOT-MELT ADHESIVE

摘要

PROBLEM TO BE SOLVED: To provide a tacky adhesive usable as a substitute for a double-coated adhesive tape, preventing the generation of gas caused by the evaporation of solvent while keeping high tacky adhesivity and enabling easy formation of a pattern with ultraviolet rays. SOLUTION: The ultraviolet-curable tacky adhesive containing dispersed hot-melt adhesive is produced by using an ultraviolet-curable tacky adhesive as a main material and mixing the material with at least one kind of a particulate hot-melt adhesive having a maximum particle-to-particle distance of 10-300μm measured by projecting the particles on a two-dimensional plane.
