Abstract: A transparent pressure-sensitive adhesive product for optical use and its manufacturing method. The adhesive product has, upon affixing, stable peeling site selectivity between release sheets and both faces of a transparent pressure-sensitive adhesive product. The transparent pressure-sensitive adhesive product for optical use has an adhesive face (a) and an adhesive face (b) of dissimilar tackiness, and is formed of an addition reaction-type silicone gel. A relationship between an adhesive power (Ga) of the adhesive face (a) and an adhesive power (Gb) of the adhesive face (b) is Ga<Gb; the adhesive power (Ga) and the adhesive power (Gb) yield a ball number from 3 to 15 and a ball number difference from 2 to 12, in an inclined ball tack test (inclination angle 30 degrees) according to JIS Z0237.

Abstract: A transparent pressure-sensitive adhesive product for optical use, a transparent pressure-sensitive adhesive laminate for optical use and a manufacturing method thereof, which afford, upon affixing, stable peeling site selectivity between release sheets and both faces of a transparent pressure-sensitive adhesive product, and which accomplish, in a stable and easy manner, peeling site selectivity on both faces of the transparent pressure-sensitive adhesive product during rework involving re-affixing. The transparent pressure-sensitive adhesive product for optical use has an adhesive face (a) and an adhesive face (b) of dissimilar tackiness, and is formed of an addition reaction-type silicone gel.
