Abstract
Articles include a substrate, and a layer disposed on the substrate, the layer being at least one hot melt processable pressure sensitive adhesive that has been coated and photocrosslinked. The adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture of a first (meth)acrylate monomer containing an alkyl, alkenyl, or aryl group with 4-20 carbon atoms, a second (meth)acrylate monomer containing an alkylene oxide group that is capped with an alkyl group, a co-polymerizable reinforcing monomer, a co-polymerizable photocrosslinker, and an initiator.

An article comprising:
- a substrate;
- and
- a layer disposed on at least a portion of the substrate, the layer comprising at least one hot melt processable pressure sensitive adhesive that has been coated and photocrosslinked, the at least one hot melt processable pressure sensitive adhesive comprising a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture comprising:
- at least one first (meth)acrylate monomer of general formula I:
- wherein R1 is hydrogen or a methyl group;
- and
- R2 is an alkyl, alkenyl, or aryl group comprising 4-20 carbon atoms;
- and
- at least one second (meth)acrylate monomer of general Formula II:
- wherein R1 is hydrogen or a methyl group;
- and
- R3 is an alkylene oxide group that is capped with an alkyl group;
- at least one co-polymerizable reinforcing monomer;
- at least one co-polymerizable photocrosslinker;
- and
- at least one initiator.
