Abstract
There is provided a photosensitive resin composition for microlenses. A photosensitive resin composition for microlenses including a component (A), a component (B) and a solvent. The component (A): a copolymer having a maleimide structural unit of Formula (1) and a repeating structural unit of Formula (2). The component (B): a photosensitizer (in Formula (2), R0 is a hydrogen atom or a methyl group; R1 is a single bond or a C1-5 alkylene group; R2 is a thermally cross-linkable monovalent organic group; and in the repeating structural unit of Formula (2), R0s are optionally different from each other).
Claims8
A photosensitive resin composition for a microlens, comprising:
- a component (A);
- a component (B), which is a photosensitizer;
- and
- a solvent;
- wherein:
- the component (A) is a copolymer comprising:
- a maleimide structural unit of Formula (1);
- a repeating structural unit of Formula (2);
- and
- at least one repeating structural unit represented by Formula (3) and Formula (5), wherein the copolymer does not comprise a repeating structural unit of Formula (4):
- where:
- each R0 is independently a hydrogen atom or a methyl group;
- each R1 is independently a single bond or a C1-C5 alkylene group;
- R2 is a thermally cross-linkable monovalent organic group comprising a blocked isocyanate group;
- X is a C1-C5 alkyl group, a C5-C6 cycloalkyl group, a phenyl group, or a benzyl group;
- and in the alkyl group, the cycloalkyl group, the phenyl group, and the benzyl group, some or all hydrogen atoms are optionally substituted by a halogen atom, a carboxy group, a hydroxyl group, an amino group, or a nitro group;
- and
- Y is a biphenylyl group or a C1-C8 alkoxy group;
- and in the biphenylyl group, some or all hydrogen atoms are optionally substituted by a C1-C10 alkyl group, a halogen atom, a carboxy group, a hydroxyl group, an amino group, or a nitro group.
