Abstract
An adhesive composition includes an acryl copolymer having a carboxyl group, and a silane compound represented by Formula 1 or 2, thereby it is possible to exhibit excellent initial adhesiveness and adhesive durability under severe conditions, and prevent the substrate from being torn due to a decrease in adhesiveness by water applied thereto, and the adhesive from remaining on the substrate during peeling-off the adhesive layer, as well as after drying, the adhesive layer may exhibit favorable adhesiveness again, thus being used for re-bonding.
Claims9
An adhesive composition, comprising:
- an acryl copolymer having a carboxyl group;
- and
- a silane compound represented by Formula 1 or 2 below:
- wherein R1 and R2 are each independently an alkyl group having 1 to 12 carbon atoms or an aryl group having 6 to 14 carbon atoms, wherein at least one of R1 and R2 is disconnected by O, S, CO or COO, and the alkyl group or the aryl group optionally includes unsaturated bonds;
- R3 is an alkylene group having 1 to 12 carbon atoms which is optionally disconnected by O, S, CO or COO;
- R4 and R5 are each independently an alkyl group having 1 to 6 carbon atoms;
- and
- n is an integer ranging from 0 to 2;
- wherein R1 is an alkanylidene group having 1 to 10 carbon atoms;
- R2 is an alkylene group having 1 to 12 carbon atoms;
- at least one of R1 and R2 is disconnected by S, CO or COO;
- R3 and R4 are each independently an alkyl group having 1 to 6 carbon atoms;
- and
- n is an integer ranging from 0 to 2.
