Abstract
Provided herein is a photosensitive resin composition which is patternable and exhibits adhesion even after being crosslinked. The photosensitive resin composition includes a (meth)acryl-based polymer having a carboxyl group and a reactive double bond on a side chain and having a specific acid value and a specific content of reactive double bond, and a photopolymerization initiator.
Claims15
A photosensitive resin composition comprising:
- about 100 parts by weight of a (meth)acryl polymer comprising
- a carboxyl group, and
- a reactive double bond on a side chain,
- wherein the (meth)acryl polymer has an acid value of about 65 to about 180 KOH milligrams per gram, and a content of a monomer unit comprising the reactive double bond of about 0.5 to about 18 mole percent, based on a total content of monomer units in the (meth)acryl polymer;
- and
- about 0.5 to about 10 parts by weight of a photopolymerization initiator,
- wherein the content of the (meth)acryl polymer and the content of the photopolymerization initiator are based on weight of the (meth)acryl polymer.

A method of preparing a photosensitive resin composition comprising:
- contacting
- a monomer comprising a carboxyl group, and
- a monomer comprising a reactive functional group, to provide a copolymer;
- contacting the copolymer with a compound comprising a reactive double bond and a group capable of reacting with a reactive functional group, to provide a (meth)acryl polymer, wherein the (meth)acryl polymer has an acid value of about 65 to about 180 KOH milligrams per gram, and a content of a monomer unit comprising the reactive double bond of about 0.5 to about 18 mole percent, based on a total content of monomer units in the (meth)acryl polymer;
- and
- contacting 100 parts by weight of the (meth)acryl polymer with about 0.5 to about 10 parts by weight of a photopolymerization initiator, based on the weight of the (meth)acryl polymer, to prepare the photosensitive resin composition.
