PURPOSE:To obtain the titled composition having excellent nonstaining property, heat-resistance and weather-resistance and suitable for a pressure-sensitive adhesive product such as pressure-sensitive adhesive tape, label, etc., by compounding a polyether having hydrolyzable silicon group with a specific amount of a petroleum hydrocarbon. CONSTITUTION:The objective composition can be produced by compounding (A) 100pts.wt. of a polyether containing at least one hydrolyzable silicon group and having a main chain composed of the recurring unit of formula -R-O- (R is bivalent alkylene) with (B) 10-150pts.wt. of a petroleum hydrocarbon having an aromatic-aliphatic copolymerized structure having decreased amount of double bond in the molecule.
