1. A photo-curing and strippable adhesive composition comprising:
a polyurethane acrylate oligomer (A); a compound having an ethylenically unsaturated group (B); a photoinitiator (C); and a polyolefin wax (D); wherein said polyurethane acrylate oligomer (A) comprises an aliphatic polyurethane acrylate oligomer (A-1) and/or aromatic polyurethane acrylate oligomer (A-2); the compound having an ethylenically unsaturated group (B) comprises a compound (B-1) selected from the group consisting of Formulae (1), (2) and (3), in Formulae (1) to (3), R1 independently represents —(CH2CH2O)— or —(CH2CH(CH3)O)—; R2 independently represents an acryloyl group, a methacryloyl group or a hydrogen atom; R3 independently represents a hydrogen atom, a C1 to C6 alkyl group or an aryl group; in Formula (1), a total number of the acryloyl group and methacryloyl group is 5 or 6; in Formula (2), a total number of the acryloyl group and methacryloyl group is 3 or 4; in Formula (3), a total number of the acryloyl group and methacryloyl group is 3; n independently represents an integer of 0 to 6, and a total number of n is 3 to 24; m independently represents an integer of 0 to 6, and a total number of m is 2 to 16; l independently represents an integer of 0 to 10, and a total number of 1 is 3 to 30; and x represents an integer of 0 to 3. |
