Abstract

Provided are a photosensitive composition for pulse exposure including: a coloring material A; a photoradical polymerization initiator B; and a radically polymerizable compound C, in which a content of a radically polymerizable compound C1 having a weight-average molecular weight of 3000 or higher is 70 mass % or higher with respect to a total mass of the radically polymerizable compound C.

First claim

What is claimed is:

a coloring material A;
a photoradical polymerization initiator B; and
a radically polymerizable compound C,
wherein a content of a radically polymerizable compound C1 having a weight-average molecular weight of 3000 or higher is 70 mass % or higher with respect to a total mass of the radically polymerizable compound C, and
the radically polymerizable compound C1 includes a repeating unit having an ethylenically unsaturated bond group at a side chain and a repeating unit having a graft chain.

2. The photosensitive composition according to claim 1 ,
wherein the coloring material A is a pigment.

3. The photosensitive composition according to claim 1 ,
wherein a content of the coloring material A is 50 mass % or higher with respect to a total solid content of the photosensitive composition.

4. The photosensitive composition according to claim 1 ,
wherein a content of the photoradical polymerization initiator B is 2% to 10 mass % with respect to a total solid content of the photosensitive composition.

5. The photosensitive composition according to claim 1 ,
wherein a total content of the coloring material A and the radically polymerizable compound C1 is 80 mass % or higher with respect to a total solid content of the photosensitive composition.

6. The photosensitive composition according to claim 1 ,
wherein a content of the radically polymerizable compound C1 is 60 mass % or higher with respect to a total mass of compounds having a weight-average molecular weight of 3000 or higher in the photosensitive composition, the compounds excluding the coloring material A and the photoradical polymerization initiator B.

7. The photosensitive composition according to claim 1 ,
wherein the radically polymerizable compound C1 has an acid group.

8. The photosensitive composition according to claim 7 ,
wherein an acid value of the radically polymerizable compound C1 is 30 to 150 mgKOH/g.

9. The photosensitive composition according to claim 1 ,
wherein an amount of an ethylenically unsaturated bond group in the radically polymerizable compound C1 is 0.2 to 3.0 mmol/g.

10. The photosensitive composition according to claim 1 ,
wherein a weight-average molecular weight of the radically polymerizable compound C1 is 5000 to 40000.

11. The photosensitive composition according to claim 1 ,
wherein the radically polymerizable compound C1 is a dispersant.

12. The photosensitive composition according to claim 1 ,
wherein the radically polymerizable compound C includes the radically polymerizable compound C1 and a radically polymerizable compound C2 having a molecular weight of lower than 3000, and
a content of the radically polymerizable compound C1 is 93% to 99.5 mass % with respect to a total content of the radically polymerizable compound C1 and the radically polymerizable compound C2.

13. The photosensitive composition according to claim 1 , which is a photosensitive composition for pulse exposure to light having a wavelength of 300 nm or shorter.

14. The photosensitive composition according to claim 1 , which is a photosensitive composition for pulse exposure under a condition of a maximum instantaneous illuminance of 50000000 W/m 2 or higher.

15. The photosensitive composition according to claim 1 , which is a photosensitive composition for a solid-state imaging element.
