Abstract
A (meth)acrylate ester includes a (meth)acrylate moiety having an ester oxygen, an anthraquinone moiety having a transmittance spectrum producing blue light, and a linking group covalently bound to the ester oxygen and to a ring of the anthraquinone moiety, the linking group including, as a first component: phenyl, naphthyl, a linear alkyl group having from 1 to about 6 carbons, a branched alkyl group having from 3 to about 6 carbons, a cycloalkyl group having from about 3 to about 20 carbons, or a substituted aromatic group.
Claims16
A (meth)acrylate ester, comprising:
- a (meth)acrylate moiety having an ester oxygen;
- an anthraquinone moiety having a transmittance spectrum producing blue light;
- and
- a linking group covalently bound to the ester oxygen and to a ring of the anthraquinone moiety, the linking group including, as a first component:
- a ring-containing moiety selected from the group of phenyl, naphthyl, a cycloalkyl group having from about 3 to about 20 carbons, or a substituted aromatic group, wherein a ring of the ring-containing moiety is directly bonded to the ester oxygen.
A method of synthesizing a (meth)acrylate ester, the method comprising:
- providing an anthraquinone compound having an anthraquinone moiety and having a reactive group attached to a ring of the anthraquinone moiety, the anthraquinone moiety having a transmittance spectrum producing blue light;
- reacting a linking group compound with the reactive group such that the linking group compound becomes covalently bound to the ring of the anthraquinone moiety, the linking group compound including, as a first component:
- a ring-containing moiety selected from the group of phenyl, naphthyl, a cycloalkyl group having from about 3 to about 20 carbons, or a substituted aromatic group;
- and
- reacting a (meth)acrylic acid-derived compound with the linking group compound such that a ring of the ring-containing moiety becomes directly covalently bound to an ester oxygen of the (meth)acrylate ester.
A method of manufacturing a camera, the method comprising:
- providing a sensor array;
- and
- mounting a color filter proximate to a sensor array, the color filter including a blue filter region therein, wherein:
- the blue filter region includes a pattern of blue color photoresist, and
- the blue color photoresist includes a polymer having a backbone at least a portion of which corresponds to a (meth)acrylate, the (meth)acrylate including:
- a (meth)acrylate moiety having an ester oxygen;
- an anthraquinone moiety having a transmittance spectrum producing blue light;
- and
- a linking group covalently bound to a ring of the anthraquinone moiety, the linking group including, as a first component:
- a ring-containing moiety selected from the group of phenyl, naphthyl, a cycloalkyl group having from about 3 to about 20 carbons, or a substituted aromatic group, wherein a ring of the ring-containing moiety is directly bonded to the ester oxygen.
A camera, comprising:
- a sensor array;
- and
- a color filter proximate to the sensor array, the color filter including a blue filter region, wherein:
- the blue filter region includes a pattern of blue color photoresist, and
- the blue color photoresist includes a polymer having a backbone, at least a portion of the backbone corresponding to a (meth)acrylate that includes:
- a (meth)acrylate moiety having an ester oxygen;
- an anthraquinone moiety having a transmittance spectrum producing blue light;
- and
- a linking group covalently bound to a ring of the anthraquinone moiety, the linking group including, as a first component:
- a ring-containing moiety selected from the group of phenyl, naphthyl, a cycloalkyl group having from about 3 to about 20 carbons, or a substituted aromatic group, wherein a ring of the ring-containing moiety is directly bonded to the ester oxygen.
