Adhesive composition for skin and adhesive tape or sheet for skin comprising the composition

An adhesive composition for application to skin comprising an acrylic copolymer obtainable (100 parts by weight) of a monomer mixture comprising an alkyl ester monomer of (meth) acrylic acid (40-80 wt%), a monomer ethylenically unsaturated group containing an alkoxy (10-60 wt%) and ethylenically unsaturated monomer containing a carboxy group (1- 10 wt%) and a glycerine ester of saturated acid (20- 120 parts by weight) , which is liquid or paste at room temperature, wherein the acrylic copolymer has a gel fraction of 20-80% by weight, wherein the gel fraction is measured by weighing the adhesive [weight (W1)], immersing the adhesive in toluene at normal temperature for 7 days and extracting soluble components, filtering insoluble matter through a polytetrafluoroethylene membrane having an average pore size of 0, 2 m, drying and weighing said insoluble matter [weight (W2) ]; and calculating the gel fraction from the formula: Gel fraction (%) = [W2 / (W1 x A / B)] x 100, wherein A = weight (g) of (acrylic copolymer + crosslinking agent) B = weight (g) of (acrylic copolymer + cross linking agent + glycerine ester of saturated fatty acid + other additive)
